Research of Test Method for the natural vibration frequency of bogie

摘要

In order to determine the,a test bench for the natural vibration characteristics of the bogie suspension was put forward.Firstly the natural vibration characteristics structure composition and the testing principle was introduced,the sine sweep incentive was simulated,and the inverse kinematics solution model and the real-time solution model were developed.The Comparison of the simulation result and the geometric theory results was carried out,proving the accuracy of the inverse kinematics solution model and the simulation model.
