| 摘 要： | 集材机轮胎静载试验值用最小二乘法拟合,显示其载荷-变形关系为一多项式,由此可计算出不同载荷下轮胎的静刚度和有效结构刚度。轮胎的载荷-变形特性与充气压力,载荷的大小及频率,轮胎的种类、尺寸,结构、使用年限及磨损等因素有关。

| Abstract: | Curve fitting with the static testing data of logskidder tires by using the least square method shows that the load-deflection relation is a polynomial, from which the static stiffness and effective stiftness of the tire structure can be calculated. The load-deflection performance depends on type, size, structure, age and wearing value of tires with varying filling presure, as well as the vulue and frequence of load etc |
