基于ADAMS的曲柄滑块机构运动仿真研究

应用ADAMS软件建立曲柄滑块机构的虚拟样机,对曲柄滑块中做往复运动的滑块进行运动学分析。运动仿真表明,曲柄转速一定,曲柄大小的改变对滑块的速度和加速度有较显著影响,对连杆影响较小;此外,滑块加速度在近半个运动周期时间内基本保持稳定。这些结果对以曲柄滑块机构为原型的设备设计开发具有参考价值。

Motion Simulation of Slider Crank Based on ADAMS

The ADAMS software was applied to establish the virtual prototype of crank slider mechanism, and the slider of crank slider to do reciprocating motion kinematics analysis was carried out.The motion simulation shows that,under the rotational speed of the crank,the change of the lider crank size had a sig-nificant effect on its velocity and acceleration and the linkage effects is small;in addition,the slider accel-eration in half a cycle time maintained the basic stability.These results are helpful f for the design and de-velopment of the devices using the crank slider mechanism as the prototype.
