Effect of Increasing Door on Vehicle Body’s Vertical Bending Stiffness
摘要
Abstract
The research was conducted on certain high-speed pure vehicle body which had different doors. The first order vertical bending modal was obtained by the test method. Then, the first order vertical bending stiffness was calculat-ed by using modal test consequence in the case of the cross section geometric dimensions and the distribution of quality of vehicle body was unknown. Finally, the curve fitting by using piecewise cubic Hermite interpolation was done. The study has shown that vertical displacement and the first order vertical stiffness of vehicle body were"W"type distribution. The result has certain significance in the design of vehicle body's cross section stiffness .关键词
