为提高救生舱壳结构的抗冲击能力,设计了一种拱形救生舱,并对该舱体壳结构进行0.3 MPa压力下的静力分析;然后在Workbench中使用MOGA方法对影响舱体强度的主要参数进行目标驱动优化分析,得到各参数的敏感度曲线和响应图及候选优化设计点。结果表明最优点在舱体质量改变最小情况下,应力水平降低25.64%,为救生舱生产厂家设计舱体提供理论支持。
In order to improve the impact resistance of the living shell structure, an arched rescue capsule was designed and the static analysis of the shell structure was carried out under the pressure of 0.3 MPa. Then the MOGA method was used in the workbench to determine the impact strength The main parameters of the target-driven optimization analysis, the sensitivity of each parameter curve and response maps and candidate optimization design points. The result shows that the optimum point reduces the stress level by 25.64% with the minimum change in the mass of the cabin, providing theoretical support for the design of the cabin of the rescue crew.
