【Abstract】 In the establishment of motorcycle multi-body dynamic model based on virtual mocking technology ,the virtual dynamic model of the entire motorcycle more close to reality is built by transmission of finite element & flexible motorcycle frame .The vibration emulation results of rigid and flexible motorcycle frame model under the input of the spectrum of road surface roughness are compared ;it indicates that the virtual mocking of motorcycle based on flexible motorcycle frame is closely in accord with the reality.更多还原
