Abstract: In view of the fact that vehicle modeling does not reflect
the high frequency vibration completely, the classical vibration theory
and impact wave theory are applied to simulate the helical spring
suspension vehicle vibration and analyse its response. The theoretical
support of impact wave mechanics to analyse the vehicle vibration is put
forwoard. And the expression equation of the wave resistance of helical
spring stress wave is developed. Wave resistance force and deformed
force vibration models of vehicle are setup. Helical spring inertia
force and deformed force vibration models of vehicle are setup based on
the effect of the impact wave on the helical spring length and
corresponding mass. The wave theory modeling of vehicle vibration of
helical spring suspension is setup under considering many factors. And
the solutions to model are also discussed and compared with all the
models in theory and solution. Simulation and test prove consistency of
impact wave theory model and classical vibration theory model in low
frequency domain and satisfying the shortcomings of the latter which can
not express high frequency vibration. It is concluded with the
application method of helical spring parameters and the simulation
method of high frequency response of suspension in wave theory.
