摘要
车辆平顺性是车辆在行驶过程中对振动的适应度的性能,对其的影响因素较多。应用三维建模软件Soldworks和机械系统动力学仿真分析软件ADAMS,建立矿用汽车在随机路面和波形路面输入条件下的平顺性仿真模型,并进行各种工况的仿真。分别改变车速、悬架刚度、簧载质量、簧载质量质心位置、路面不平度等影响整车平顺性的因素,分析这些因素对平顺性的影响程度。仿真结果表明,矿用汽车满载比空载工况行驶平顺性更好;满载时,将油气悬架的刚度等效为线性刚度来分析汽车的振动情况,误差较小;分析结果为进一步设计分析提供参考。
Vehicle ride comfort is the performance of the vehicle's adaptability to the vibration in the process of driving,and the influence factors are more. The dynamic simulation model of the ride comfort of the mining dump truck in the random road and the waveform of the input condition has been established with software ADAMS and Soldworks. The model is simulated,while the factors affecting riding quality such as velocity,stiffness of suspensions,location of the mass center of the truck body upon the suspensions and road surface roughness has been changed individually. The simulation results have shown that the body vibration is more intense while no load than full load. The error is smaller when suspension equivalent stiffness as linearity to analyze truck vibration under full load conditions. The analysis results provide references for the further design and analysis.
