根据光电设备机箱模块锁体的载荷和约束条件要求, 按照锁体最小质量原则和实际使用工况, 对锁体的相关参数进行优化仿真, 通过 UG NX7.0有限元软件对锁体给出相关参数设置, 软件多次对质量和草图驱动尺寸进行迭代计算, 计算结果趋于收敛, 得出锁体在满足强度和刚度的条件下质量最小, 经分析计算和试验验证, 满足了设备减重要求, 为整机其他零件进行优化设计提供了参考。

Based on the requirements of photoelectric equipment chassis module lock body loads and boundary conditions, according to the minimum weight principle on the lock body and the actual operation conditions, relative parameters of the lock body are optimum simulated. The relevant parameters setting of the block body is given by UG NX7.0 finite element software. The weights and the driving dimension of sketch drawings are iteratively calculated by the software. The results trend to convergence. And the minimum weight of a block body is got on the condition of certain strength and stiffness. The requirement of equipment weight loss is met through analysis and calculation and the optimized design reference are provided to system and other parts.
