目的 研究在理论条件下,推烟机构推手装置中曲柄滑块机构的动态运动情况。 方法 借助动力学分析软件 ADAMS 对曲柄滑块机构进行研究,分析其运动学曲线和动力学曲线。 结果 直观形象地仿真出了曲柄滑块的运动情况。 结论 通过对相同速度下推手中曲柄滑块的研究,获得了其位移、速度、加速度的曲线图,并研究了当曲柄受到临界载荷 F = 80 kN 的阻力时,其驱动力矩的大小和方向的变化情况,最终获知当阻力改变方向时驱动力矩恰为 0 。

Objective To study dynamic movement of the slider-crank mechanism in the driver equipment of push smoke mechanism under theoretical conditions. Methods With the help of the dynamics software ADAMS, the motion curve and dynamic curve were obtained for the slider-crank mechanism. Results Using this method, intuitive simulation of the movement of the driving force mechanism was achieved. Conclusion Through studying the crank slider in the push hand at the same speed,curves of displacement, velocity and acceleration were obtained, and the size of the drive moment and the change of direction were studied when the sliding block suffered from the resistance from an exercise load of F = 80 kN, and finally it was found that the driving moment was 0 N·mm when the resistance direction changed.
