| Abstract: | This paper discusses the simulation method of vehicle ride comfort under pulse input by using visual prototyping technology. The multibody system model of one electric tractor developed by Beijing Institution of Technology including suspensions, vehicle body and person-chair system are built. The tire-terrain interaction is calculated using UA analytical tire model and three-dimensional road model. After simulation, the tractor ride comfort is evaluated, and the effects of suspension and chair parameters are analyzed at the tractor's design stage. |
