基于Pro/E、ADAMS、ANSYS及MATLAB多款软件联合仿真,建立了新型平行轴齿轮传动的采煤机截割部刚柔耦合模型,应用ADAMS/Vibration模块对其进行振动分析,通过观察系统的主要振型获知截割部的各激励源不会激发截割部系统发生共振,但观察系统第33阶振型,发现在截割部质心附近,出现了较大的扭转振动,为了提高该采煤机截割部的稳定性,对其传动系统进行了优化,结果表明:优化后截割部质心处x、y、z3个方向上的加速度响应幅值分别降低了74.2%、64.83%、7.02%,扭转振动明显减小,其他测试点振动幅值也都明显减少,此外壳体的自由模态和约束模态的变形幅值也得到明显改善,分别减少了95.9%和93.98%,优化效果显著。
Based on the co-simulation of Pro / E, ADAMS, ANSYS and MATLAB, a new rigid-flexible coupling model of shearer cutting section with parallel shaft gear drive was established. Vibration analysis was carried out by ADAMS / Vibration module. The main vibration mode is that the excitation source of the cutting part will not stimulate the resonance of the cutting part system. However, observing the 33rd vibration mode of the system, it is found that there is a large torsional vibration near the centroid of the cutting part. The results show that the amplitude of acceleration response in the x, y and z centroid of the cutting part is reduced by 74.2%, 64.83% and 7.02 respectively %, The torsional vibration is obviously reduced, the amplitude of vibration of other test points is also obviously reduced. In addition, the deformation amplitude of the free mode and constrained mode of the housing is also significantly improved, reducing by 95.9% and 93.98% respectively, and the optimization effect Significant.
