【摘要】 本文应用配气机构有限元动力模型对顶置气阀下置凸轮轴配气机构进行了动力计算,计算结果与实测数据相符,并用此模型对6102Q柴油机配气机构在各种转速工况下进行了动力分析,求出了该机构运动规律、接触应力、振型、自振频率及气阀弹簧各圈的运动和振动。更多还原

【Abstract】 The valve gear in an overhead valve engine was calculated with the dynamic model of finite element method in the paper. The calculated results were closely agree with the experimental data. Using this method, the dynamic analysis for the valve gear was made in various operating conditions for 6102Q diesel engine, to get the kinematics, contact stress, vibration modes, natural frequency and the vibration of each circle of valve spring .更多还原
