Measure and Appraise Rideability of Truck Vibration

In the paper,a vehicle vibration model was set up by using simulink software,and the simulation analysis of truck vibration was made under different vehicle speeds and road surface conditions.According to the National Standard GB/T 4970-1996,the variety tendency of rideability under different road conditions was analyzed.And also,the road tests were conducted with three different type of trucks.The results show that the rideability and ridecomfort of the trucks become worse with the increase of vehicle speed and road unsmoothness.So the rideability of truck needs improved.
