Research on Simulation Technology of Virtual Rig for Commercial Vehicle
With a heavy duty truck as research object,we use the interactive method of Abaqus explicit/implicit solution technology to establish a vehicle flexible & nonlinear dynamics simulation model,which considers many nonlinear factors like leaf spring,tires and rubber bushings.Compared with the bench test under the same conditions,the established model has higher precision.Based on this,we make simulation of the 6-channel road simulator test on the vehicle with finite element model.The test results show that stress error of main structure is less than 25％,pseudo-damage value from simulation is similar with measured value.
