The dynamic performance and the theory and basic law ofthe constant speed control are theoretical and experimental results are construction and working principles ofapower-trans mission test bench and amechanical dynamometer analyzed .Control policy about the mechanical dynamometer is described,then the matching method ofthe control system and the pivotal parameter are gained. Dynamic analysis ofthis model isfinally demonstrated indetail 。This paper analyses and discusses position ofthe multifunction test and operating principle,and presents test, method ofcont toand structures bining test .Adesign idea ofmultifunction test bed isput forward which issuitable for different driving form and test test results show that system runs steadily,saves energy remarkably,loads conveniently, andsatisfies 充值下载即送 CAD 图纸, QQ 36396305 req
