【摘要】 依据 GB4970-85 汽车平顺性随机输入行驶试验方法对 SY6480 轻型客车进行室外道路试验。测得了座椅、地板和车桥的振动加速度。结果表明:随着车速的增加,座椅和地板振动加速度功率谱的幅值有所增加;在车速相同驶时,沙石路面的振动的幅值比沥青路大。最后用综合振动舒适度评价法对 SY6480 轻型客车的平顺性进行评价。更多还原

【Abstract】 In this paper, an experiment of light bus SY6480 is carried out on a road according to the national criterion GB4970-85 called the testing method of automobile ride comfort with random input. The accelerations of seats, floor and axles are obtained. The result shows that the vertical accelerations of seat and floor increase with the increase in speed; and the vibration on the rough road is great than on the pavement road. Finally, an evaluation on the ride comfort of light bus SY6480 is conducted.更多还原
