Abstract

Abstract: Based on the H-point machine (HPM), a detailed simulation model of body pressure distribution on seat is established in this paper. The material parameters of foam and fabric closely related to the simulation analysis of body pressure distribution on seat are obtained through tensile and compression tests. The reliability of the model is validated by comparing the maximum pressure, average pressure, contact area and weight ratio in different regions. The results show that the established model can not only accurately reflect the general rule of body pressure distribution, but also can accurately reflect the body pressure distribution indexes of shoulder, waist and thigh of the H-point machine. The error between the simulation and test is less than 10%, and the seat simulation model is effective.

Key words: seat, body pressure distribution, test , foam, simulation, comfort
