Tsikot.ph PHUV Prototype

[dprox]

I agree with that...kung ang exterior ay pangit... wala talagang market potential yan, no matter how good the technology is.
x x x
For me I will go for FORM OVER FUNCTION... simple compromise for function is an inevitable sacrifice for form.

DESIGN should not be reduced to "form" (aka styling - whether exterior or interior). Maraming issues.



It's not simply "form vs function" anymore. The design process is a series of decisions, and in every decision - no matter how small - you have to answer FOUR basic questions:

1. > AESTHETICS - Is it pleasant to the senses of the beholders?
2. > UTILITIES - How useful is it, really?
3. > ENGINEERING - Is it doable and safe?
4. > ECONOMICS - Is it affordable to the target market?

These are the four balls a designer must continuously juggle in the design process. On rare occasions, economics is not an object. At other times, aesthetics is the priority over the other three. For military and construction vehicles, it's utility and engineering over aesthetics and economics.

As you can see, priorities can vary among these four criteria, depending on the project. The lower ranking criteria should consistently serve the requirements of the highter priorities.

As with most UVs, for the Tsikot PhUV, the order of priorities would be :

1) Economics
2) Utility
3) Engineering
4) Aesthetics

By no means does this imply that it's OK to have a lousy look. Rather it says that we should strive to have the coolest look and feel possible, without sacrificing the first three criteria. The challenge is to come up with the "coolest" (aesthetic) vehicle possible which serves the higher priority criteria.

To all of you who have an ME background, my next contribution would be to get my hands on a CFD (Computational Fluid Dynamics) Simulation Software and share it with you guys to make the task of engine design easier for those who are interested. Software simulators nowadays are so darn accurate that you can model practically everything in the virtual world and know to a certain extent that it will function as designed in the real world. We can bypass the "nuts and bolts" not to mention the huge budgets of doing it the old way. [/SIZE]

* TAMBAY..

thanks man.

can you FEA?

do you know of any sites that offer free 3D models of car parts? in 3DS, DWG, or DXF formats

[TambayBlues]

You're welcome bro, To answer your question If I do FEA or Finite Element Analysis, No I'm not at that level yet. But I do believe that there are talented Mechanical or Structural Engineers from the rosters of DLSU or any good engineering school for that matter who are capable of undertaking this task. AFAIK its basically used for Stress Analysis and also has broad applications in the automotive engineering field especially with regards to safety of the elements or parts of a car. I'm still just a newbie in this whole car design thingy and basically am still at the research stage which I'm quite good at. If you want free 3ds car models follow these steps..

1). Go to u*******.com
2). Download their client software then install it.
3). Run the u******* client (you will notice it's green u icon with a circle at the lower right hand corner of your desktop).
4). Go to Btjunkie.org and at the search bar type 3ds models the press the search button and you will get a list in the results panel. Double click the ones with a green bar at the meter found on the right side of the panel. Those ones are the active files and the ones with red bar are basically inactive and cannot be downloaded. Just confirm the ******* download instructions with the Ok button. When you switch over to u******* client you will find its already downloading. Right click the file being downloaded to give you more menu options like priority and speed etc. When its finished you can just double click the file to open it or you can open its containing folder. In case you're wondering, I'm an Industrial Engineer so my forte is more on the production side of things but I've also had some 3d AutoCAD modelling background. Hope this helps.

Thanks Tambay,

Actually, what I want are exact 3D models of car parts. Yung galing dun sa manufacturer. This way, I can easily build a complete, exact model...with real existing parts.

[safeorigin]

did i just heard someone say engine design??? wow, that's my queue!!!

Although not impossible, looking for 3D models of car parts on the internet would be a difficult task given that most manufacturers regard it as a trade secret and as a matter of confidentiality would probably only share it with companies that they have collaborations with. You can also try searching for machinist plans but if the source is quite dubious the accuracy of the measurements might be doubtful and even then they might not necessarily be free. At this point, I would suggest downloading some reverse engineering books and or software like geomagic, rapidform etc. which would be an easier task and buy/build a 3D scanner so you can just digitize the actual parts themselves to create the 3d models. Still, you might have to tweak the digitized data a bit depending on how accurate your scanner is.

I just found a whole catalog of 3D car models / parts etc. just don't know if it came from manufacturers or just the work of modelers. There's a free option but you have to register and upload some models to get some credit for free download. You can try downloading the ones you found at Btjunkie then upload it to this site to get the credits. Here's the link;

If that does'nt suit you I just found Geomagic at Btjunkie and you can also learn from these other sites;

This one looks more legit and seems like it's free. You need to download Viewpoint media player to view, rotate, zoom the models etc. Here's the link;

yup, i know rapidform. I am actually trying to revive a 3D scanner at work. medyo pinabayaan kasi bulky. Its made with 2(yes, 2 for speed) minolta vivid 900 3D scanners. it has a turntable to automatically rotate the object. right now im using a trial software, pati yung rapidform trial.

i have actually tried downloading 3D parts..sa thomas.net, kaya lang pang utility vehicle bodies e. you're suggestion to download and then upload is a good idea. i'll probably try it when i find the time.

DIY 3D scanner! hmmm interesting

nasubukan ko na yan. di ko nagustuhan.

[TambayBlues]

Found this CFD simulation software that most OEMs use for auto parts and systems development especially the engine, aircon, cooling and exhaust etc. Read nyo na lang literature, ganda ng features nya kasi me sarili na syang library of automotive components that you can just drag and drop into your design. I'm also downloading Ricardo Wave v7.1 kaso di pa lang tapos search nyo na lang either emule or btjunkie.

http://www.flowmaster.com/V7_automotive.html

Anyways, I found Flowmaster sa emule parang u******* din sya me sariling
client software. You can try downloading it from there. I don't know if it's the same software maybe an earlier version but just the same it would add another set of tools for those aspiring auto parts designers.

Here's another book about making your own pistons and rebuilding old ones.

If there is a better time to catch up with the west in terms of technology it is now, considering that most of their research is available or accessible via the internet. Most of the cutting edge research and software to speed up development time can be downloaded / obtained for free or at a fraction of the cost in most cases that I'm sometimes amazed at how powerful all this information is. Here's another software tool that they actually use to test the safety of their cars. Take note from the attached image of how close the actual car performed in the crash test as opposed to the virtual model. If you have a software this accurate then you only need to make minor modifications to your digital model if ever. It can be daunting at first but it sure beats actual physical prototyping and crash testing precisely because it costs practically nothing except of course one's time. Here's a little info and the download link. Try to download it in the soonest opportune time coz they might remove it if you know what I mean.


PAM-CRASH 2G 2005

PAM-CRASH 2G advanced features encompass:

First predictive rupture model available in the industry that provides accurate answers to the deformation of materials such as composites, high strength steels and aluminum. Car manufacturers currently resort to materials which sustain high crash test performance, but their narrower plasticity ranges increase rupture probability. By integrating predictive rupture model PAM-CRASH 2G perfectly matches the physics of these materials.

Fast and easy input/output procedures in combination with new editor for data checking and user-friendly graphic environment help reduce modeling time.

Up to 50% performance increase in memory saving based on scalable contact structure and dynamic memory allocation within the streamlined solver architecture. PLM concept compliance which allows collaborative engineering and mission critical decision-making.

Withstanding accidental collisions has become a primary design criterion for the occupants of vehicles. With the shortening of design cycles, crash test simulation is a crucial competitive issue for car manufacturers. PAM-CRASH 2G capabilities answers the industry's needs for a wide range of specific applications. Here's the download link;

Sir Dprox,

saan na po yung PHUV version ng Chokaran?

[TambayBlues]

Its a pity we are look upon by foreigners as mere consumers, and inferior to them--in fact in America, a guy from a radio station, denounced Filipinos in America as pretenders who think they are at par with the Asians (Chinese, Koreans and Japanese) by having the same fancy cars, which they think Filipinos, our race cannot afford. We are perceived as a pathetic bunch of wannabees who cannot even produce a decent vehicle unlike our Asian/ASEAN neighbors.

If you're referring to the Filipino hate letter supposedly from Art Bell, I think you should read this link so you can get the real score;

[knight23]

meron ba kayong mga 2d cad design diyan? i can do aerodynamic simulations on FLUENT.

[donbuggy]

It seems that aerodynamics were not a high priority in the design of the PHUV. We could therefore conclude with scientific certainty that the PHUV's coefficient of drag is equivalent to that of a brick.

correct!

maybe he can do air flow efficiency for AC systems.

Hello everyone, my name is John Carlos. I've been following this thread for a long time now. Just recently a British supercar was launched- the Keating SKR. They say that the body styling was created by a Filipino. I think if we can tap this pinoy designer, the PHUV project can benefit specially with the styling.
Here's some links to their website.

Guess what? A simple research shows the Keating SKR was designed by Lagangan Automobile Designs, which is based right here in Manila.

Since the email addy used is cadcollaboration.com, my guess is that Lagangan Automobile Designs is also based in Taguig.

*dprox - possible for you to initiate the contact?

*carrora - thanks for the info!
