【摘要】 用有限元法对服役状态的摩托车铝合金轮毂进行了应力分析。结果表明:轮毂服役应力集中主要出现在轮辐与轮圈的过渡圆角区域,且该区域所承受的是非对称循环应力。在此基础上对最大交变应力值进行疲劳强度校核,表明轮毂在摩托车规定的正常服役期内是安全可靠的。更多还原

【Abstract】 Stress of Al motorcycle wheel under the service condition was analyzed with finite element method (FEM). Wheel service stress concentration mainly occurred in the transition areas of rim and spoke, where the presenting stress was nonsymmetrical circulation one. The maximum alternation stress was checked according to fatigue strength criterion, which indicated the structural wheel was secure in the period of natural service of wheel.更多还原
