摘要
为客观准确地评价液力变矩器流场仿真模型的可信度,对某型液力变矩器进行了300次性能试验,并按照与试验完全相同的输入量对流场仿真模型进行300次仿真计算,将仿真结果和试验结果进行了对比。基于复杂性测度理论,建立了仿真与试验两组数据系统单变量、两变量和多变量等3个层次的可信度评估体系,并提出复杂性、关联性和稳健性3种仿真模型可信度量化指标。结果显示,该流场仿真模型的整体可信度为72%。
In order to objectively and accurately evaluate the credibility of hydrodynamic torque converter＇s flow field simulation model,300 performance tests of one hydrodynamic torque converter were conducted,and a same number of simulation using the same input variables with the tests was also carried out.Results of both the tests and simulation were compared.Based on theory of complexity measurement,a credibility evaluation system covering three levels,including single-variable,dual-variables and multi-variables was set up,and corresponding quantitative credibility indexes based on complexity,relevance and robustness were put forward.The results showed that overall credibility of the simulation model was 72%.
