For now the user is constrained to place the ramp in the yellow and green positions to make the problem simpler

With the single sensor I first measure the surface, then I measure the ramp. So when the sensor is on the ramp I already measured the surface angle. I'm thinking I could just add or subtract the angle measured when the sensor was on the surface? This would negate the surface's affect on the ramp...

I'm hoping someone here could help me with a problem I am having. I have an electronic sensor that measures tilt, and I put this sensor on a 10 degree ramp. The problem is that this portable ramp is put on surfaces that the levelness is unknown. It can vary up to +/- six degrees. The bottom of...

I was wondering how I can estimate the damping coefficient of my car by doing the hand bouncing the car body and watching the motion of the car? Mechanics usually bounce the car by applying hand force and watching how the car moves in harmonic motion. Is there a way to estimate the damping...

If I count every time the car goes above the ride height that is a half sine (half of a cycle) ??

Confused :/ any help thank you AlephZero

Thank you! For the damping, the half-cycles would be the peak to peak every time it comes "up" correct? If I video tape it I will just need to know the FPS of the camera to get a time scale like they do on myth busters?

So you mark a reference point, jack the car up until the tire barely lifts off the ground, that distance from the reference is the displacement, and I use the car weight as the force as listed in the owners manual? Or would I use 1/4 of the weight since its one tire?

I'm working on a project, I just need ballpark estimates for the spring constant and damping coefficient for my 1994 Nissan Pathfinder SUV. I was thinking of using Hookes law to estimate the spring constant, can I just measure the ride height of the car with nothing in it, then add 200 pounds...

I've done transfer functions for electronics, mechanical is kinda new to me, trying to figure it out haha

Thanks, if I run into trouble could you help me? First I want to do this on a remote control car that has a spring suspension, adding small weight to it, would it scale to a real car as an estimate using the same method just bigger weights?

Yeah I want to estimate it, I'm not sure how though. I just need a simple approximation , I was just brainstorming fender ride height and loading increasingly heavier weights into the car and measuring the displacement, but I'm not sure if that's correct way to do it

I like this idea, from the data how would I deduce the transfer function? One accelerometer on each wheel then the accelerometer in the cab of the car. The one in the cab would be the affects of all four, but I think the front and rear of the car have different suspension, how would it all tie...

I need to estimate the overall damping property of the suspension to tie all the theory together and have complete information, can you point me to methods or equations. It doesn't have to be exact just a ball park estimation to compare real world results to.

AH well my idea is to put the accelerometer on the frame itself between the two wheels past the back axle. However, I'm very curious on how to estimate the "spring constant" or damping coeffient of the suspension, I was thinking of adding weight and measuring displacement of how much the frame...
