【Abstract】 Based on the analysis of human exposure to whole body vibration in recumbent position in a highway sleeper bus,a seven freedom model is established.With random input of road surface irregularity of the front and rear wheels,the frequency responses on the recumbent person’s head,buttock and legs are simulated.The calculation results are compared with the results of road tests.更多还原
