Make this man youtube famous, his videos are extremely accurate and very well explained. Thank you for making this content, and please continue to do so!
Thank you for your very clear video again ! Could you make a video on how to calculate the right spring stiffness ? Like you did with the ideal brake curve ?
I guess the wheel and its associated components would be considered sprung mass in relation to the tire tread's "unsprung mass" on the pavement. I speculate this is why a good tire at certain inflation pressures can have a major impact on ride quality for high frequency bumps. The tread on the pavement may be only 0.3 kg and the rest of the wheel dynamic components may be 30 kg giving a 100:1 sprung to unsprung ratio for the modeling of the wheel components. It would be interesting to see what impact this has on overall comfort and performance and what are good ratios for this subsection of the suspension?
That is correct but the impact is small. In reality, the unsprung mass of most vehicles is in the 50-65 Kg range, so your ratio is more like 200:1. Also, the spring rate of a tire is usually on the order of 300-350 N/mm which is about 10x the spring rate of the suspension. There is also relatively little damping in a tire to go along with this high spring rate. Having said all that, there is a school of thought that says that high unsprung mass is not necessarily a bad thing because it forces the tire to do more work over those small high frequency bumps. But it's really not the right way to do it. There are better ways to absorb that high frequency energy in the mounting system of the springs and dampers. Tires are a wear-out item and you don't want the ride comfort of your car to suddenly drastically change when the customer needs to replace their tires.
hello sir can you post a series on DESIGNING A SUSPENSION GEOMETRY FOR A FSAE CAR - DOUBLE WISHBONE, DAMPER TO LOWER ARM TO BODY or PUSH ROD SUSPENSION, I will be waiting sir i request you sir

This is the best video on this topic on yt. Subscribed.
What a find! Straight to the point and a fantastic explanation. Immediately subscribed

Love your videos!

You might get more responses if you stop typing in all-caps like you’re yelling.
@@TranceFur also stop posting the exact same text on several videos... looks like a bot.
Cool
WOWWWWWWWWWWWWWWWWWWWWWWWWWWWWW look at the Ford GT extrusion on the shelf. There are only a few of those in the world!
You should look in to voice acting/voice over jobs
