摘　　要：基于道路模拟试验激励和约束方式,建立了摩托车五自由度人-车多体动力学模型,应用拉格朗日方程建立了系统运动微分方程和状态方程。通过对海南试验场采集的道路载荷谱进行室内模拟迭代,得到了某摩托车道路模拟激励信号。以该激励信号为输入,编制MATLAB程序对摩托车进行了动力学仿真,并借助道路模拟试验机进行了试验验证。结果表明,结合道路模拟和计算机仿真能对摩托车动力学性能进行准确分析和预测。A 5--DOF multi--body dynamics model of motorcycle was derived based on the inputs and constraints of road simulation tests, and the differential equation of motion and state--space formulation were developed according to Lagrange equation. By iterating the load spectra, which was sampled on Hainan proving ground, the driving signals of motorcycle road simulation were obtained, with the driving signals as inputs, the motorcycle dynamics was simulated using MATLAB program, then the simulations and experiments were compared. The results show that motorcycle dynamics can be analyzed and estimated precisely by combining road simulation with computer simulation.
