Commercial Vehicles Thrust Rod Static and Dynamic Characteristics Analysis 2016-01-2345

In order to study the static and dynamic characteristics of the thrust rod. Based on the multi-body dynamics theory, the dynamic model of the thrust rod and the vehicle system is established by using ADAMS software. The limit braking condition is simulated, and the limit braking load of the thrust rod is obtained. Thrust rod finite element model is established, the load calculation value and rubber test data as a finite element analysis of input conditions, using ABAQUS software to carry on the stiffness and strength analysis, analysis results show that the strength meets the requirement, and the stiffness and strength calculation result is in good agreement with the sample test, accurately describes the finite element model. The analytical method used can be used to predict the stiffness of the thrust rod. Thrust rod finite element modal analysis were carried out to obtain the thrust rod as a whole and local low order vibration mode and natural frequency, contrast the calculated values and experimental modal value error is small, in the project within the allowable range, indicating that finite element modal analysis result is accurate. The obtained results provide theoretical guidance for the optimization of the thrust rod structure.
