摘要
基于实验数据的灵敏度分析是一种可靠有效的分析方法,详细阐述了ANSYS中基于实验数据的灵敏度分析基本原理,为基于ANSYS的结构灵敏度分析提供参考;应用ANSYS对一个Schw-edler型单层球面网壳进行了灵敏度分析,得出了几种结构响应对于杆件的灵敏度值,将不同位置的杆件对于几种结构响应的影响程度进行了量化,可为该类型单层网壳的设计及响应控制提供参考,通过对计算结果的分析验证了基于实验数据灵敏度分析的高效性和可靠性。
The sensitivity analysis （SA） based on experimental data is a reliable and effective method, the basic SA theory based on the experimental data in ANSYS is presented in detail, which can be a reference of structural SA using ANSYS. A Schwedler single-layer dome is analyzed by using ANSYS, and the sensitivity values of several structural responses to dome members are calculated, which quantify the influence degree of members to the structural responses, so the result can be for a reference of the design and response control of the single-layer dome. The analysis of the calculated results verifies the reliability and effectiveness of SA based on experimental data
