摘要
在载荷校准试验方案设计中,规划加载工况是主要内容。加载工况设计的目标是既能使载荷方程有足够高的精度,又不至于有太多冗余工况。为了提高试验效率,保证载荷方程精度,本文基于载荷校准虚拟试验,研究了载荷方程建模工况数量以及建模工况选取对载荷方程精度的影响,提出了载荷校准试验加载方案优化设计方法。
In the design of the load calibration test plan,the planned loading conditions are the main content.The goal of the load case design is to enable the load equation to be of sufficient accuracy without too many redundant conditions.In order to improve the efficiency of the test and ensure the accuracy of the load equation,this paper studies the influence of the number of load equation modeling conditions and the selection of the modeling conditions on the accuracy of the load equation based on the load calibration virtual test.The optimization design method of the load calibration test loading scheme is proposed.
