Simulation of Vibration Isolation Performance and Optimization of Engine’s Mounting System
摘要
Abstract
To solve the problem of engine’s excessive vibration in idle condition, the mounting system of an inline four-cylinder diesel engine was studied. By means of the dynamic simulation software GT-CRANK for diesel engines, a virtual prototype model of the mounting system was set up. Its vibration isolation performance was simulated for different stiffness of the mount system. The influences of variation of the mount stiffness in different directions on the vibration isolation performance of the mounting system were analyzed. Under the constraint conditions of reasonable matching between system’s natural frequency and mount spacing requirements, the optimization design of the mount system was given. After the optimization, the average vibration isolation rate was raised from 82.34 % to 88.74 % and the isolation performance of the mounting system was obviously improved.关键词
