应用ADAMS软件，建立了包含人体、前后悬架、车架、转向系在内的某全地域四轮车的多刚体动力学模型。利用谐波叠加法模拟了符合国家标准的B级路面不平度，并生成路面文件。分析了发动机激励，在ADAMS中施加了发动机激振力和力矩。在考虑发动机激励的情况下，对该车在随机路面输入下进行了平顺性仿真，并用MATLAB编制了全地域车客观评价方法对其座位处和手把处的振动进行了评价，为进一步设计分析打下良好基础。

A multirigidbody dynamic model of an allterrain vehicle (ATV) is established in MSC.ADAMS. The model takes into consideration the body, suspension, frame and the steering system. According to the method of superposition of harmonic wave, a Grade B road file is created in ADAMS for the riding comfort test. The engine excitation is analyzed. The infliction for engine excitation to ADAMS is achieved. The ATV ride comfort simulation is carried out with the excitation of the engine, and the seat vibration is evaluated using an evaluation method programmed via MATLAB. It has laid a good foundation for further analysis.
