A comparison between the results obtained by the finite element method and by measurements is then carried out,considering the size of tire contour,the curve of load-deflection,the contact patch.

Marc軟件對(duì)子午胎進(jìn)行了三維非線性有限元分析,分析中考慮了輪胎的材料特性、結(jié)構(gòu)特點(diǎn)、胎圈部與輪輞的摩擦接觸以及輪胎與地面的摩擦接觸等,比較了輪胎的外緣尺寸、負(fù)荷-下沉量曲線以及輪胎接地印痕大小、接地壓力分布等,有限元計(jì)算結(jié)果與實(shí)測(cè)結(jié)果相當(dāng)吻合。
