摘　　要：针对凸轮机构的驱动力矩计算问题,提出了相应的向量键合图方法。基于凸轮机构的运动约束条件,阐述了建立平面凸轮机构向量键合图模型的一般方法,揭示了其所包含的动力学原理。在混合因果关系的情况下,推导出系统驱动力矩(驱动力)的统一公式,特别适用于计算机自动计算。通过实例说明该方法的有效性。For the driving moment calculation problem of cam mechanism,the corresponding vector bond graph method was proposed.Based on the kinematics constraint condition of cam mechanism,the general procedure for modeling planar cam mechanism by vector bond graph was described,and its dynamic principle was presented.Under the condition of mixed causality,the unified formula of system driving moment or driving force has been derived,which was very suitable for automatic calculation on a computer.The validity of proposed method is illustrated by a practical example.
