Abstract EN
In accordance with dropping shock dimensionless cubic nonlinear dynamic equation of suspension spring system, by variational iteration method, a first-order approximate solution of the system was obtained.
The nondimensional peak of displacement, the nondimensional peak of acceleration, and the dropping shock extended period were compared with the results of the Runge-Kutta method, at which relative errors were less than 4%.
The influence of suspension angle on peaks of response were discussed.
It shows that the maximum response nondimensional acceleration decreases with decrease of the suspension angle under condition of the same nondimensional dropping shock velocity.
Conditions for resonance were obtained by applying the variational iteration method, which should be avoided in the packaging design.
The results provide reference for suspension spring system design.
