Example 1: The point moving back and forward, what does it map to on the car, and what is the dampening?
Submitted by: haomiao Submitted on: October 4, 2004 Identifier: L2.1 The point moving back and forth corresponds to the bottom of the tire. The input forcing is the ground, so when the ground goes up and down it also forces the tire up and down. Obviously this is a very simplified model which wouldn’t take into account gravity. The damping would represent the fluid in the suspension shock absorber. [Back to Top] • In the mass-spring system modelling the car, one of the springs is fixed to a wall. How does that model the car when that “spring” on the car is connected to the chassis? Submitted by: waydo Submitted on: October 4, 2004 Identifier: L2.1 If the weight of the car is very large compared to the effects of the driving force on the suspension, then modelling the car as a fixed wall with springs is not a bad approximation. However if it is not the case, the boundary conditions you would have in order to model a suspension system in a car may be diffrent. You may leave out the wall
