摘要

摘要: 为使车载稳定平台在动态载荷状态下满足系统精度要求,对车载光电稳定平台外框架进行了优化设计。介绍了外框架材料的选择原则与外框架的结构形式;运用UG软件对外框架进行三维建模;采用理论分析与有限元计算相结合的手段,对外框架结构进行了分析与设计;并基于MSC软件进行了仿真校核。结果表明:本文设计的外框架能在满足刚度强度的前提下实现较小的转动惯量,静力状态下的最大变形量为2.6 m,满足使用要求。

Abstract: An external borner for the vehicle opto-electronic stabilized platform was optimized to improve its system accuracy under a dynamic loading mode. The material choice principle and structure mode of the external bordon were introduced. Then, the external border was molded by using UG software, and its structure was analyzed and designed with the finite element method combined with a theoretical analysis. Based on the MSC software, the model was checked and verified. Experimental results demonstrate that the designed border can achieve a smaller rotation inertia with better rigidity and strength and its maximum distortion is 2.6 m in a static state. The result means that this structure can satisfy the operating request.
