Modeling, dynamic analysis and optimization of Budsan truck engine mount

Abstract

This research presents dynamic and vibrating analysis of Budsan truck engine mount. First the system equations are presented and solved by MATLAB. After that, the dynamic forces exerted on the system are obtained and used for the harmonic analysis. Then the FEM results are compared with analytical model results to verify analytical model. Finally, the optimum stiffness as well as the damping of the system are presented and discussed to reduce the system vibration and avoid the resonance phenomena. The results show that an increase in the stiffness of the system from 2943 to 5500 kN would reduce the displacement from 7 to 3.5 mm and an increase of the stiffness to 5500 kN and a hystersis from 0.285 to 0.5 could reduce the displacement from 7 to 2 mm. © 2008 Asian Network for Scientific Information.
