Abstract: 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.
