Use of CAE Tool to Evaluate the Body Pressure Distribution Plot on Automotive Seating 2019-01-0402

Body Pressure Distribution (BPD) plot plays a vital role during designing the seating system. The seating system provides support and comfort to the occupants while they are operating the vehicle. The traditional way to produce Body Pressure Distribution (BPD) plot for a seating system is to use actual human subject with pressure sensor mat. But this is only possible when the seat has been manufactured. The purpose of this paper is to demonstrate the capability of CAE analytical tool to find the BPD plot at the early phase of the seating system design. BPD plot created by using SAE standard manikin is not very realistic as that dummy back and butt is not deformable compared to human manikin dummy. Human manikin back and butt is made of deformable finite element tissue which gives more realistic direction of body pressure distribution. With the help of CAE analytical tool, the traditional process is streamlined, and a seat design could be achieved in a shorter period with greater accuracy. We will show the correlation between actual BPD and CAE result.
