摘　　要：发动机的活塞-连杆-曲柄机构的惯性力和惯性力矩是摩托车振动的主要振源之一,准确计算其惯性力和惯性力矩对整车性能分析具有重要的意义.将活塞-连杆-曲柄机构简化为三质点模型,根据质系动量定理,推导得出了机构的惯性力和惯性力矩计算公式,并对某200CC摩托车发动机的惯性力和惯性力矩进行了计算.The inertial force and moment brought by piston, link and crank running are one of primary prompting sources for vibration of motorcycles. Calculating the inertial force and moment is needed to analyze the quality of motorcycles. In this paper, a three-particle model is presented, which simplifies the piston-link-crank system. Based on the momentum theorem, the function to calculate inertial force and moment is educed and is used to calculate a 200CC motorcycle engine.
