Abstract

Cylindrical grid shells made of modern composite materials by automated continuous winding that have a high degree of weight perfection and are widely used in aerospace engineering are considered. The problem of using such structures as deep-submergence vehicle bodies operating not under external pressure is discussed. The problem of optimal design of cylindrical grid shells based on the criterion of minimum mass under constraints imposed on strength and stability is considered. By minimizing the safety factors for possible forms of destruction, an analytical solution that determines the optimal design parameters of the composite grid shell is obtained.

外力作用下复合圆柱网格壳的优化设计

摘要

考虑了由现代复合材料通过自动连续缠绕制成的圆柱状栅格壳，该栅格栅格壳具有很高的重量完美度，并广泛用于航空航天工程中。讨论了使用诸如在深水车身中而不在外部压力下运行的结构的问题。考虑了在强度和稳定性的约束下，基于最小质量准则的圆柱格栅壳的优化设计问题。通过最小化可能破坏形式的安全系数，可以获得确定复合网格壳体最佳设计参数的分析解决方案。
