摘要
提出了在用车工况法尾气排放测试系统中底盘测功机转动惯量的汽车等效质量的可溯源的测试方法。同美国BAR 97提供的测试方法进行了对比测试和分析,指出了BAR 97方法的不足,提高了底盘测功机加载滑行测试的准确度。
A traceable measuring method for dynamometer inertia weight is firstly presented,which is used in chassis dynamometer for the loaded-mode emission test of in-use vehicles. This method is compared with the one used in BAR 97 ( US standards) ,and the test results are analyzed. Some of shortcomings of BAR 97 are listed. The new test method can improve the accuracies of the loaded coast-down test of chassis dynamometer.
