基于OpenFresco平台混合试验时长研究

OpenFresco平台是实现混合试验的重要途径,试验时长是混合试验中的关键因素。混合试验时长可以分为数值子结构计算时长,系统交互时长,加载时长三部分。本文以单层单跨框架模型为分析对象,取钢柱构件为试验子结构,根据时长试验结果系统研究影响混合试验时长的因素。通过对试验数据系统分析,得出积分方法、模型复杂程度、加载步长是影响混合试验时长的主要因素。根据不同积分方法、模型复杂程度、加载时长等工况的试验结果,通过比较得出试验时长与试验精度的关系。

Study on Test Duration of Hybrid Simulation Based on OpenFresco Platform

OpenFresco platform is an important way to realize the hybrid simulation process, and the test duration is a key factor for hybrid simulation. The duration of the hybrid simulation is divided into three parts: the calculation duration, the communication duration, and the loading duration. In this paper, a one-story one-bay frame is selected as the prototype structure. A steel column specimen designed for multiple tests is adopted as the experimental substructure. Furthermore, the factors affecting the hybrid simulation duration are studied in detail from experiment results. It can be concluded that the integration method, the model complexity, and the ramptime are the main factors affecting the hybrid simulation duration. According to the test results of different integration methods, model complexity, and ramptime, the relationship between test duration and test accuracy is obtained through comparison.
