Everything checks out, to my eyes. That's the traditional generalization about suspensions... all masses are point masses, all forces are 1D, all spring rates are constant.
If you want to trick it up, you can do:
- progressive spring rate = f(x-x_0)
- linear damping = k * (x-x_0)'
- digressive damping = f((x-x_0)')
- damper hysteresis = nasty equations)
- pressure-sensitive tire rate = k_sidewall + k_air * pressure (absolute)
- temperature-sensitive tire rate = k_sidewall + k_air * n*R/V * temperature (absolute)
- tire temperature estimation = T_atm + k * log (T_tread - T_air_in_tire)
- tire tread temperature = T_atm + k * (heat generated - heat dissipated)
... lots of ways to complicate the problem.
