A new type of vibration platform was presented and its dynamic characteristics was studied. A virtual prototype model of vibration platform was built by using software SoldWorks and ADAMS.The flexible body model of spring was built based on ADAMS flexible module,rigidflexible coupled dynamic of vibration platform were analyzed by using simulation, the natural frequency, model of vibration and frequency response were further analyzed. The stiffness of spring and flexible cable were optimized according to the analysis results.The postoptimality simulation results show that the stability and frequency response of vibration platform are improved.
