以某发射装置为研究对象,为减轻发射装置的重量、方便拆装并改善其静动态性能,对发射装置进行拓扑优化,以得到更优的发射装置结构。在对装置进行受力分析的基础上计算出其工作时的受力大小,利用SIMP插值方法建立了拓扑优化数学模型,使用solidThinking Inspire软件对发射装置分别进行以静态刚度最大和以静态刚度、动态平均频率最大为目标的多目标拓扑优化,得到发射装置拓扑优化结果。结合实际情况,在Pro/E软件中重构发射装置三维模型,将模型导入ANSYS分析其应力和模态。经过检验,新的发射装置与原来的相比重量减轻了近一半,其静动态性能更优,说明优化结果合理。
Taking a launching device as the research object, in order to reduce the weight of the launching device, facilitate disassembly and improve its static and dynamic performance, the launching device is topologically optimized to obtain a better launcher structure. Based on the force analysis of the device, the force magnitude of the device is calculated, and the topology optimization mathematical model is established by SIMP interpolation method. The solidThinking Inspire software is used to simulate the launch device with the maximum static stiffness and the static stiffness, The maximum average frequency of the target multi-objective topology optimization, the transmitter topology optimization results. According to the actual situation, the three-dimensional model of launch device was reconstructed in Pro / E software, and the model was imported into ANSYS to analyze the stress and mode. After testing, the new launcher reduces the weight by nearly half compared with the original one, and has better static and dynamic performance, which shows that the optimization result is reasonable.
