摘要
为在室内比较全面考核摩托车车架在实际道路行驶载荷作用下的疲劳可靠性,结合车架有限元分析建立了摩托车车架道路载荷谱采集方法,并对道路载荷谱进行了采集和分析。在分析摩托车车架实际行驶受力情况基础上,基于远程参数控制技术,结合美国MTS液压伺服作动器和控制系统,设计并搭建了一套多轴向多激励摩托车车架道路模拟试验平台,并提出了力-位移混合控制的道路载荷谱模拟迭代方法。结合所采集的摩托车车架道路载荷谱,采用力加载控制和惯性加载控制混合加载控制方式,在室内对摩托车车架道路载荷谱进行了高效准确的模拟,并建立了摩托车车架多轴向多激励道路模拟试验方法,为在室内考核摩托车车架的疲劳可靠性提供了一种行之有效的方法。
To achieve comprehensive indoor assessment of motorcycle frame fatigue reliability under impact of moving load on real roads,an acquisition method of road load spectrum based on a finite element analysis of a frame was established,and the collection and analysis of road load spectra were then completed.A multi-axial and multi-channel road simulation tests platform for motorcycle frame test was designed and built,based on the analysis of practical driving load of motorcycle frames,combining with the remote parametric control （RPC ） technology and the American MTS hydraulic servo actuator and control system.An iterative method of simulating road load spectrum with force-displacement mixed control was put forward.Applying the collected road load spectra of motorcycle frames and adopting a loading control mode,mixing the force loading control and inertial loading control,the road load spectrum of motorcycle frames was efficiently and accurately simulated indoor.A multi-axial and multi-channel road simulation test method for motorcycle frames was established,an effective indoor method for fatigue reliability assessment of motorcycle frames was provided.
