摘要
作动器输出机构的变形可以看作是输出轴体扭转变形与摇臂变截面悬臂梁变形的综合。从材料力学的角度出发,详细推导了作动器输出机构机械刚度的理论计算方法,并以此理论为依据对作动器输出机构的结构进行优化设计。通过仿真对比确定优化设计的正确性,为工程应用提供了有力的理论支撑。
The deformation of the actuator output mechanism can be regarded as the synthesis of the torsion deformation of the output shaft and variable cross-section cantilever beam deformation of rocker arm.Proceeding from mechanics of materials,the theoretical calculation method of actuator output mechanism stiffness is deduced in detail and the optimization design of actuator output mechanism is finished according to the theory.The correctness of the optimization design is validated by simulation,which provides great theoretical support for the engineering application.
