中文摘要:
      目的 应用图解法对金属成形加工机械执行机构进行设计, 并基于ADAMS和Pro/E软件对机构进行建模仿真及分析。方法 根据测量出各铰链受力情况选取典型构件作为柔性构件, 在ADAMS柔性模块中对相应刚性构件进行柔性替换, 并比较冲头的位移、 速度、 加速度、 曲柄力矩等曲线。结果 当机构高速运转时, 原动件速度为360 (°)/s, 柔性构件对冲头的位移、 速度、 加速度都造成了影响, 其中对位移曲线影响不大, 对速度、 加速度曲线影响明显, 对机构的稳定性造成了一定影响。结论 当设计高速机构时, 必须考虑构件的柔性因素对机构运动特性的影响。
英文摘要:
      Metal forming machinery actuator was designed using the graphic method, and simulation modeling and analysis were conducted for the actuator based on ADAMS and Pro/E. According to the force measurement of each hinge, typical components were selected as the flexible components. Flexible replacement of rigid components was conducted in the flexible module of ADAMS, and the punch displacement, velocity, acceleration, crank torque curves were compared. The results showed: during the high-speed operation, the driver speed was 360 (° )/s, the displacement, velocity and acceleration of the punch were affected by the flexible components. There was obvious influence on the velocity and acceleration curves, while relatively insignificant influence on the displacement curve. And the stability of the actuator was also affected. When designing high-speed mechanism, the influence of flexible factors on the motion characteristics of the mechanism should be considered.
