Abstract

In this study, parametric sensitivity was assessed based on a theoretical model of a composite cylinder under internal pressure. By varying the fiber volume content, number of layers, wound angle, internal pressure, and thickness of prepreg, the response objects of stresses and displacement were achieved. Besides, a global and local sensitivity analysis of objectives was conducted under different stacking sequences. The results show that the input variables exhibit different levels of influence with the change in targets. Moreover, a stronger response of objectives is caused by some variables selected in a special range.

内压下多层绕丝圆柱体的多参数灵敏度分析

摘要

在这项研究中，参数灵敏度是基于内部压力下的复合圆柱体的理论模型进行评估的。通过改变预浸料的纤维体积含量、层数、缠绕角度、内压和厚度，实现应力和位移的响应目标。此外，在不同的堆叠顺序下对目标进行了全局和局部敏感性分析。结果表明，随着目标的变化，输入变量表现出不同程度的影响。此外，在特定范围内选择的一些变量会引起目标的更强反应。
