带有非轴对称球锥过渡环壳的球面舱壁优化设计

Optimization design of domed bulkhead with nonaxisymmetry sphere-conical transitional annulated shell

系统分析了带有非轴对称球锥过渡环壳的球面舱壁的结构组成、受力工况、强度与稳定性要求,用有限元方法对各参数进行了强度优化与稳定性优化。最后用某中型艇的非轴对称球锥过渡环壳的球面舱壁进行实例分析,对比优化前后球面舱壁的重量值及强度与稳定性性能。

In the article we analyse the structure compose,the endure force status,the request of strength and stability on the domed bulkhead with nonaxisymmetry sphere-conical transitional annulated shell.The various parameters of the strength and the stability have been optimized by the method of the finite element.Finally,the weight,the strength and the stability of the domed bulkhead with nonaxisymmetry sphere-conical transitional annulated shell of some middle-size submarine before and after optimization have been contrasted with examples.
