轿车座椅R点预测及体压分布研究
Research on R Point Forecast and Body Pressure Distribution of Car Seat
摘要
Abstract
Taking a car seat as the research object,the R point is predicted and body pressure distribution is evaluated in this paper based on MADYMO software.By consulting the R point measurement of the national standard GB11551-2003 Ride Position H Points and the Actual Angle of the Back Angle of the Program,the R point of the prediction method is obtained based on this standard.Based on the ideal body pressure distribution map,the comfort of body pressure distribution is evaluated by using the characteristics of the ideal body pressure distribution,the maximum pressure Pm and the symmetry.The calculation results show that,the results of the two prediction only differ by 0.001,and R point prediction method is accurate and has the value of practical application;the seat cushion foam stiffness in the range of 0.8 ～ 0.9 times,makes the best comfort of different shape of occupants.关键词
