摘　　要：为了从整体上掌握摩托车的振动特性,提高其乘骑舒适性,采用面向整车系统的数字化功能样机技术,对某国产摩托车使用三维建模软件UG建立了车架、手把、前后悬架、后平叉的数字化三维模型,进行装配后整体导入多体动力学软件AD- AMS,并施加与实际摩托车相同的约束、力和运动,构成了六自由度的摩托车整车数字化功能仿真模型。根据试验的等级路面的功率谱密度函数,编写了相应的路面文件,并通过ADAMS对该车在所编写的路面上进行了平顺性虚拟试验。研究结果表明,对于摩托车这一复杂的系统,建立详细的数字化功能样机,可以有效地分析其平顺性。This paper employs the Functional Digital Prototyping and 3D modeling software UG to establish a digital 3 D model for frame, handle, front and rear suspension, and rear fork. After assembling , these parts are entirely inducted to multiplex dynamics software ADAMS. The same restraint, force and motion of the real motorcycle are ex- erted on them to form a 6 DOF digital function simulation model of the entire motorcycle . In addition, based on the PSD of certain road, this paper establishes corresponding documents about the road and makes a virtual test of ride comfort on the established road via ADAMS. From this study, it can be concluded that it is effective to analyze the ride comfort of motorcycle by establishing the detailed Functional Digital Prototyping.
