Coilover Shock absorber | Coil spring designing | Damper calculations | Mounting points of coilover

Coilover shock absorber is a suspension device in which coil is mounted over the damper/shock absorber. It allows to adjust the Ride height , camber & damping of the vehicle. While designing the coilovers , many factors are considered such as, wheel rate, spring rate, installation ratio/motion ratio ,ride rate , tire rate etc. In this video i will be covering each of these parameters for designing coil springs and calculations for dampers.
In this video you will learn:-
1)What is coilover shock absorber?
2)Damping calculations & Designing of coil spring
3)How to determine mounting points of coilovers?
4) Spring rate, wheel rate , Ride rate ?
5) What is installation / Motion ratio ?

You are a life saver... Literally! I've been dreading of suspension calculations for long... But this!!! This video just made things as easy as it gets!!! Plus, now I understand these stuff from machine design... Thankyou so much! And great work!!!way to go!!!!

[@thevatsaljain]

Glad it helped!

[@sudeepv5338]

The concept and procedure to be followed in designing a suspension system is clearly explained n well understood. But I'm having problem in considering right values and units, so it would be really great help if you could explain it considering an example with values.

[@jayakumars1336]

Hi, the effort u put in easy to understand is amazing. thank you so much for such video's. Can you make one more video for Hydro-Gas suspension systems used for off-highway dumpers, where the spring rate is non-linear and how to decide on the required damping in such case. Thanks.

[@TheSilverSmitih]

Bruh, I just wanna lower my car. I have gone down one hell of a deep rabbit hole. Thank you so much for the great information!

[@shubhamkumar7100]

your videos are too helpful thank you so much, can you please make a design calculation video for pushrod suspension? and steering calculation. Please keeping working and updating your videos.

[@orangehead484]

Excellent!! 👍🏻👍🏻

[@TheSilverSmitih]

Question: When calculating for spring rate, how do you account for wheel travel? I want to ensure that my wheels are able maintain a clearance with the fender well during full compression. Since I am modifying my own car and NOT creating a car, I am unable to adjust the top mounting point.

[@diegobula4597]

Very cool videos! I have a question, if i had to calculate the IR for a push rod or pull rod suspension how can I calculate it?

[@solankidigvijaysinh287]

Your videos are Very help full in study of V.D,,, thanks for making this great videos. 👍

[@thevatsaljain]

[@prajaygaonkar5991]

Hi, Do we need to consider anything of Pre-load while designing susp. springs? or it has to be considered only during assembly as per requirement?

[@tanaygupta_]

Amazing Boss 👌🏻

[@thevatsaljain]

Thanks 🤗

[@EpicFailPL]

Hey, your videos are a massive help to understanding some of the concepts that I'm now trying to study now. I have a question regarding your presentations. Are you making all diagrams by yourself? What software do you use to create them and animate them? It looks sooooo professional and I would love to learn the softwares as well to use them for presentations at my company. Greetigs from Poland :)

[@thevatsaljain]

Hello , Thank you. For editing and animation i use :- Adobe Photoshop and adobe premiere pro

[@golfish8589]

I wantvto build a tubevframe golf cart/off road buggy. Electric. Not gas. I want the smoothest riding buggy possible. What type of front and rear suspension do you recommend

[@thevatsaljain]

For the smoothest ride on your electric off-road buggy, consider an independent suspension system for both the front and rear. Double wishbone or A-arm setup for front suspension, providing better control and stability. For the rear, an independent rear suspension (IRS) or a well-designed trailing arm system can enhance ride comfort.

[@pedromelro4257]

hello i have a doubt. what do u mean with tire rate? it is the tire ratio, isn't it? because i didn't found nothing about that.

[@afteroffice_yt]

👍

How to find the tyre rate and how to fing the angle deta ?

[@RajendraYadav-bh3nk]

Can you please provide us video on semi Trailing arm rear suspension geometry ..

[@thevatsaljain]

I am working on it also.

How I get a tyre rate value

[@shubhojeet24]

btw what is tire rate ??

[@jaygurjar8532]

are all your formulaes from rcvd...???

[@thevatsaljain]

Yes i referred rcvd for some formulas !

[@kalyaninadipalli1]

I am going to design a spring damper for atv. for that one we need specifications of spring and damper . So that firstly what specifications we consider spring or damper. Specifications like diameter , length no of coils like that. How should I consider for design? If any one know please comment here.

[@se_a_34_tejasgami14]

What is Kt

[@ganeshmadne3828]

i can't get tire rate!!! from where i can found it??

[@bendoherty7721]

If your in the uk and interested. Can you help me build a national hotrod

[@amithulsure5199]

Were you a part of FS or FSAE team?

[@thevatsaljain]

Nope.

[@dielauwen]

Mauw!

[@dhanushkumar4798]

How to find the tyre rate from the tyre specifications

[@thevatsaljain]

You can calculate Static tire rate using tire specification sheet, which basically gives you unloaded diameter of tire, static load diameter and maximum load rating. Using these values you can calculate tire rate.

[@raghav7200]

Thanks for this video bro but how to find the tire rate bro

[@thevatsaljain]

Tire rate can be found from tire data. Tire manufacturers gives :- Static loaded and unloaded radius or diameter with maximum load rating. So static tire rate can be calculated as K(t) = Load/deflection. Also note that tire rate is effected mostly by tire air pressure inside.

[@raghav7200]

@@thevatsaljain thanks bro

[@RbNetEngr]

@@thevatsaljain I have not seen this tire data on a manufacturer’s specification sheet. They provide the load rating, as well as the tire diameter (unloaded, I believe), but not the loaded tire diameter at the load rating. Also, if this information WAS obtained, and the tire load is a percentage of the total load rating, is it a linear change in tire rating for an applied weight that is less than the total load rating? For example, a tire I’m looking at (235/40R17) shows the following specs: LOAD I.D. SL UTQG RATING 300/AA/A UNIT WEIGHT (LBS.) 23.5 RIM WIDTH (MEAS.) 8.5 RIM WIDTH (APPR.) 8.0-9.5 OVERALL WIDTH (INCHES) 9.5 OVERALL DIAMETER (INCHES) 24.4 TREAD WIDTH (INCHES) 8.2 TREAD DEPTH 10 STATIC RADIUS (INCHES) 11.4 REV/MILE 852 MAX LOAD AT COLD INFLATION PRESSURE (LBS. @PSI) SINGLE 1323@51 TYPE BW So, is 11.4” the loaded radius?

[@jiayyi8045]

Hey, how to obtain tire rate from datasheet?

[@thevatsaljain]

You can calculate Static tire rate using tire specification sheet, which basically gives you unloaded diameter of tire, static load diameter and maximum load rating. Using these values you can calculate tire rate.

[@prishachakravorty6627]

how can I get the tire data?

[@thevatsaljain]

You can get tire maximum load capacity and the value of loaded radius from your tire manufacturer. Using those you can calculate tire rate.
