Hi you can provide me your email. I will share on it

​@@ASquareCD Where I provide my E mail id?

Hi. I will check for it. You provide your email. I will share there

Thank you.

Hi. You cam rear vertical members or rear mid cross member to provide mounting for your control link. Moreover try to watch my video on H-Arm - kzbin.info/www/bejne/gWO8nYJod6uUgMUsi=pdziC8VaJYDqjcgI

Learn Solidworks. Its user interface is easy and there are tons of video on youtube to help you. Also, use wesites like get into my pc . com to get the solidworks software.

Hi Tell me

Sir actually I see all of your videos but I need a complete playlist of design of a suspension geometry of both front and rear in solidwork works with proper assumption and then import these points in Lotus and find the optimum values of the hard point how to approach towards it​@@ASquareCD

@SameerAli-dq4zd hi. Refer this video for suspension and roll cage creation - kzbin.info/www/bejne/gaa2gqGLrN-cY8Usi=KL73aj_-KK1YSgzt

@@ASquareCD but sir it is according to the 3D sketch , actually I want to to draw suspension geometry in 2D sketch ,as it is given in book vehicle dynamics by l.milliken

You can provide your email id. I can share over their the zip file.

@@ASquareCD thanks

@@Heizenberg. can you share that to me

​@@ASquareCDHey buddy how can I get lotus software

Hi. You need link for which thing? Solidworks or the CAD files, i have used.

Noted sir, Your suggestions are welcome

Okay I will share in some time

@@ASquareCD do you need my mail?

Please share the file, you are only source of it now, don't let it die

You Get into pc .com

Will look into it

No need to insert. We can model it with the Tyre surface.

Use mass properties option.

What seats onto the rim is considered here. Tire height will be lost or gain according to pressure inside the Tyre.

You can start the calculations for deciding outer diameter and thickness of rollcage pipe. You have adhere to the minimum requirement asked in the Baja rulebook. Then after that you can create custom template as per given outer diameter and thickness and assign as per the rulebook.

Hard points are suspension crucial parameter points like [upper ball joint, lower ball joint, wheel center, wheel spindle point, shock body mount, shock suspension mount, etc.] Points which represent suspension components and linkages.

You can assume the dimension. If you are asking for knuckle length, then take 5 inches. Otherwise there is no need to give dimensions to reference lines.

Thank you. Glad you are liking the content

Hi you need the CAD file for suspension geometry?

Okay, will share

did you get it

Glad you like it.

In this suspension, I have taken the steering geometry as Anti-ackerman. So on basis of that when you view from top view, steering rack will come ahead of the line joining the both front wheel centers. And also I placed at a height so that we have space for creating mounting for it and I left clearance for the roll cage Fram pipes.

Can you share an image or something at [email protected] so that I can have a proper look.

@@ASquareCD sure

Okay, Will definitely make it.

Thanks for watching. And yeah that's a great idea. I will definitely work on that video and I will produce it soon.

@@ASquareCD it would be awesome! Have a nice day friend

No, There is no brand which gives CAD file of tyre. However you can search in Grabcad library for the CAD of the tyre you are looking for. You can also download my tyre CAD and customize it as per your dimesnions. Link is in the description. In case you dont know about the dimensions of your tyre, let me decode for you. 180/55-ZR17= 1. Rim size - R17 = 17 inches= 431.8 mm (This is rim diameter) 2. tyre width=180 mm 3. aspect ratio = 55 4. tyre profile height= 99 mm 5. Tyre overall diamter = rim diameter + 2 X tyre profile height => 431.8 + 2 x 99 = 629.8 mm 6. Z is permissible speed limit rating. Check the speed rating index for the speed. Thats it. I hope i solved your query.

@@ASquareCD thank you for replying. What I mean by dimensions is the curves and thickness of the tyre which you have set while modelling.

@@ashishac7913 yes, nice question. I previously had done a project on Tyre making, so that's how I know it. I suggest for making the inner cross-sectional profile, you need to read on Tyre construction, thickness of plies, safer groove depth, tread height, Tyre carcass thickness, sidewall height, etc. These are some terms if you Google them you can get lot of references and idea about thickness. And regarding dimensions of curves, there is no defined dimensions for them. It can be arbitrary provided you do the structural and thermal analysis of the Tyre. Based on the results of analysis, you can modify those curves as per your design boundaries.

@@ASquareCD ok will try it and thank you for helping me out.🙏

Within 2 days. Working on it currently. In that I will show how to assign the extracted coordinates to the suspension system. And thanks for watching this video😊

Hi, the second part of the Lotus suspension video is uploaded now. Check out the video- kzbin.info/www/bejne/fHnOdoxupJupfMk

@@ASquareCD Sure

You are asking for which software.? SolidWorks or Lotus?

@@ASquareCD Lotus,

Yeah. In previous years, it was present on some websites. Now i dont see it anywhere. and Every possible link available now is fake. But i can share it with you. If you can comment your email id here, i can share through Googledrive or Wetransfer.

@@tarikr5853 Here. Already uploaded it. Check if you can download it or not. Its already installed. Just unzip the file and use the software. Link- we.tl/t-qQZ8CJsmX6 Let me know if it doesn't work.

@@ASquareCD Am downloading it right now. Thank you so much, this is huge help from you. Deep thank you my friend.

Yes. Middle to Middle of both tyres.

@@ASquareCD Wow ! you are so fast to reply! thank you so much!

@@daveeeeeed9201 Yes, I try to get back asap to all the doubts and questions and I am glad I was able to solve your query. Thanks for watching the video.

Thank you 😊

You can leave those values as they are. They dont affect your analysis. I can understand you are relating it with CG, but we can define CG height and CG position by defining the weight distribution at the front and rear axles. So dont worry about them.

Thank you sir.

Yes. You see every line has 2 points in SolidWorks. And those points have x y z coordinates. Just note down coordinates of points like, Upper ball joint Lower ball joint Wheel centre Spindle end. Upper arm front pivot and rear pivot Lower arm front pivot and rear pivot Damper Upper point and lower point. Note all of them and then transfer to Lotus. Note- you need to adapt with the axis system of Lotus analyzer with SolidWorks.

@@ASquareCD yes sir, I will try it out. Thank you.

@@arnabadhikary828 thank you for watching. 👍

Hi Arnab, I have now uploaded the video on how to extract the hardpoints from a suspension geometry made in Solidworks and also how to import those extracted hardpoints in Lotus software. Check out my 2 latest videos. I have made them in 2 parts.

@@ASquareCD okay sir , thanks a lot. Will definitely check them out .

It's so simple. Click on the point where the A arm pivots on the chassis member. Click on that point and note x y z coordinate. Though I will make a short video for it.

Hi Sahil, I have now uploaded the video on how to extract the hardpoints from a suspension geometry made in Solidworks and also how to import those extracted hardpoints in Lotus software. Check out my 2 latest videos. I have made them in 2 parts.

Basically, here I have shown how to create the architecture or say 3d wireframe of a suspension/steering geometry. I have not shown the calculation part of any parameter. It is just the designing. Now, to calculate length of tie rod, you need to analyze the steering rack length and it's height + steering arm angle + steering arm length in some suspension software like LOTUS. Also, turning radius and Ackerman/ anti-ackerman percentage is also considered while evaluating tie rod length. So, that can be done as a separate video.

@@ASquareCD can you make a video on those calculations?? I would really appreciate it

@@AbdulBasit-hm4mq okay. I have noted it. I will work on that video and try to publish soon.

@@ASquareCD Thank you!

For Roll center, you need to create instantaneous center's for both front and rear suspension and from there roll center can be determined. I am bringing up the video for rear suspension geometry soon, after that I can make a video for that. For Motion ratio, you need to know your suspension travel and wheel travel. the formula is suspension travel divided by wheel travel. It can be determined from geometry as well. I will put up a video for that as well.

@@ASquareCD thanks bro

Thank you. I am glad you like it
