应用SolidWorks软件建立了压下减速器壳体的实体模型,在Simulation环境下对其进行了模态分析,得到前6阶固有频率及振型。结果表明该壳体在工作过程中不会产生共振,但各阶振动的振幅较大。为此对压下减速器壳体进行了结构动力修改,与改进前相比较,各阶最大振幅下降明显,说明结构改进措施合理,可有效抑制压下减速器壳体的振动,改善压下减速器的动态特性。
SolidWorks software was used to establish a solid model of reducer housing, and modal analysis was carried out under the condition of Simulation, the first 6 natural frequencies and mode shapes were obtained. The results show that the shell does not resonate during operation, but the vibration amplitude of each step is larger. For this reason, the reducer housing was subjected to the structural dynamic modification. Compared with the pre-modification, the maximum amplitude of each step decreased significantly, indicating that the structural improvement measures are reasonable, which can effectively suppress the vibration of the reducer housing and improve the reduction and deceleration Dynamic characteristics of the device.
