摘　　要：设计2种配方(炭黑用量为50份和40份)和3种结构(矩形、梯形和圆弧形)的履带销胶环,研究配方和结构对其疲劳寿命的影响。结果表明:炭黑用量小的配方履带销胶环的疲劳寿命比炭黑用量大的配方履带销胶环长;圆弧形结构履带销胶环的两侧应力小于矩形结构履带销胶环,且圆弧形结构履带销胶环的应力分布相对均匀,根部应力小于梯形结构履带销胶环。配方炭黑用量小和圆弧形结构履带销胶环的疲劳寿命长。The track pin rubber rings with two formulas(40 and 50 phr of carbon black) and three types of structure(rectangle,trapezoid and circular arc) were designed to study the influence of formulas and structures on their fatigue life. The results showed that,the fatigue life of the track pin rubber ring with small amount of carbon black was longer than that with large amount of carbon black. The stress on both sides of the rubber ring with circular arc structure was lower than that of the rubber ring with rectangular structure,and the stress distribution of arc rubber ring with the circular arc structure was relatively uniform. Moreover,the root stress of the rubber ring with the circular arc structure was lower than that of the rubber ring with trapezoidal structure. In general,the fatigue life of the track pin rubber ring with small amount of carbon black for formula and circular arc structure was long.
