STEADY STATE RESPONSE
ANALYSIS ON HELICAL SPRING
IMPACTED BY SHORT WAVE
Abstract:
The wave transmission character of helical spring is applied to establish 2-DOF model of impacted vehicle on the wave impact theory. Considering the concrete structure of helical spring, corresponding responses under different impact frequency of the vehicle are imitated. The reason why the vehicle floor overresponds in some special frequency fields is explored based on analyzing the responses. When the impactions are in low frequency, the change of the spring has not been considered, but this does not affect the results. Because the transmission characters of velocity and acceleration are unanimous in helical spring, the responses characters of velocity and acceleration are also unanimous, the only difference is the magnitude, which can make use of acceleration responses to analyse velocity responses.
