欲在某型三轴机床基座上安装电磁式振动能量采集器,基于折形悬臂梁弹簧能量采集器中平面弹簧的形式,提出其它几种平面弹簧的基本构型,并用CATIA软件绘制出三维实体模型。导入到ANSYS软件中建立了几种平面弹簧的三维有限元模型,通过对其进行动力学模态分析,分别求出几种弹簧的前几阶固有频率和振型,作为在结构设计过程中使得机床基座的激励响应尽量靠近弹簧系统固有频率的理论参考,以获得具有较高采集性能的能量采集器。最后对选出的结构进行谐响应分析,进一步验证选择合理性。 In order to install the electromagnetic vibration energy harvester on the base of a type of three-axis machine tool, the basic configuration of several other plane springs is proposed based on the plane spring in the cantilever spring energy harvester. The three-dimensional Solid model. The software ANSYS was used to establish three-dimensional finite element models of plane springs. Through the dynamic modal analysis, several natural frequencies and mode shapes of the springs were obtained respectively. As a result, The excitation response of the machine base is as close as possible to the theoretical reference of the natural frequency of the spring system to obtain an energy harvester with high acquisition performance. Finally, the selected structure of harmonic response analysis to further verify the choice of rationality.
