基于ANSYS的航空装备产品专用夹具设计分析

Design and Analysis of Special Fixture for Aviation Equipment Product Based on ANSYS

为了减少涡轮后盖组件加工时因夹具不稳定而引起的加工误差,根据后盖组件的结构特点和企业的工艺水平,设计了一种在加工中心上对后盖组件进行精确定位和装夹的专用夹具。详细阐述了该夹具的结构特点,并采用ANSYS对其进行静力学和模态分析。仿真结果表明该专用夹具的设计符合加工技术要求,安全可靠,达到了企业加工质量的要求。该研究方法与结果可为后续专用夹具的优化提供依据。

During the machining of the turbine rear coverassy, to reduce the machining error caused by the instability of fixture, a special fixture is designed. According to the structure characteristics of the rear coverassy and the technological level of the enterprise, it can precisely locate and clamp the back cover assembly in the machining center. The structure characteristics of the fixture are described in detail, and the static and modal analysis is carried out by ANSYS. The simulation results show that the design of special fixture meets the requirements of processing technology, safe and reliable, and achieves the requirement of processing quality of the enterprise. The research method and results can provide the basis for the optimization of the following special fixture.
