摘要

为探究摆线轮磨齿机立柱振动特性,以磨齿机立柱组件为研究对象,建立其三维实体模型,并基于有限元仿真软件ANSYS进行了预应力下的模态分析,获得了组件的各阶固有频率及对应振型。为研究磨削加工下立柱的真实振动特性,搭建了振动实验平台,对采集的数据进行了时频特性分析,探究了立柱振动的机理。实验结果表明,立柱在低阶频率特性较好,同方向下磨削工况相比自由工况,同频率附近对应峰值处的最大振幅不超过4.7%。最后从振动角度对立柱的设计及优化提出了合理化的建议。

Abstract

In order to study the vibration characteristic of vertical column of cycloid gear grinder,the three-dimensional solid model is established based on the vertical column component of cycloid gear grinder,and the pre-stress modal analysis is carried out based on the finite elements software ANSYS simulation. The natural frequency and corresponding vibration mode of the component are obtained. To study the real vibration characteristic of the vertical column,the vibration test platform is set up. Then the time-frequency characteristic of the collected data are analyzed,and the vibration mechanism of the vertical column is explored. The experimental results show that the vertical column is better in the low order frequency characteristic,and compared with the free working conditions under the same direction,the maximum vibration amplitude of the corresponding peak at the same frequency is not more than 4. 7%. Finally,the rationalization proposal for design and optimization of the vertical column are put forward from the vibration.
