Abstract
Pressure distribution of the human-machine interface is a key factor which affects the comfort. Because every part of the human body has different tolerance to pressure, high or low pressure will make the driver feel uncomfortable. Through the virtual simulation method combining 3D modeling and finite element analysis, the human body and seat finite element model is established to simulate the interaction of the contact interface, the human-seat coupling model was constructed and finally imported into ANSYS for finite element analysis and compared with the actual measured pressure distribution. The pressure distribution obtained by this method was proved to be feasible for evaluating driver comfort. When apply on seat back comfort study, the changes in the pressure distribution under various conditions can be observed by changing parameters such as seat inclination. The model can be used as a scientific basis for seat comfort assessment and optimization, and the researchers can understand the pressure on the driver’s various parts to guide the seat comfort design.
