摘要

针对使用铰链连接结构的曲柄连杆可动机构,分别建立其刚性多体系统和刚-柔耦合多体系统模型,并在同一运动控制规律下分析柔性构件弹性变形存在与否对运动机构动态响应和约束载荷的影响。对可调机构建立刚-柔耦合模型,对不同速度的系统运动规律下研究构件惯性项和杆件所受约束的载荷-时间关系,分析在同位移关系下惯性项与外力项的变化关系。最后利用多体动力学商业分析软件将多体动力学计算结果作为输入,使用有限元软件实现全运动过程中强度计算分析。
        In this essay,establishing the rigid multi-body system and rigid-flexible coupling system coupling multi-body system model for hinge structure,which is commonly used in connection structures of mechanism. By analyzing dynamic response of same motion control rule analysis in rigid model and rigid-flexible coupling mode of crank-link mechanism,evaluate the influence of flexible elastic deformation. Then analyses the inflation of different motion rule to dynamic response in rigid-flexible coupling model. The results of multi-body dynamic calculation were used as input using in finite element software to calculate the strength of the whole movement process.
