内燃叉车振动仿真及动力总成悬置优化
Vibration simulation of internal combustion forklift truck and optimization of powertrain mount
摘要
Abstract
In order to solve the problem about strong vibration of frame and obvious discomfort of human body while a inter-nal combustion forklift truck at 2650 r/min speed condition,the vibration transmission path of the internal combustion fork-lift is tested and analyzed.It is found that the main reason for the vibration of the frame is the poor vibration of the power-train.A forklift rigid-flexible coupling dynamics model is built on ADAMS by means of multi-body dynamic method and the model is verified by measured data.Under the premise of the dynamic coupling model of internal combustion forklift is basi-cally consistent with the actual vehicle model,the test design optimization method of ADAMS is used to match stiffness and damping of the forklift truck powertrain mount.The optimization results show that the total effective value of acceleration of the internal combustion forklift frame is reduced by 18% and the vibration performance of the frame is improved.关键词
