| 摘 要： | 摩托车曲轴箱体的壁厚与加强筋直接影响其结构强度.用有限元法建立了镁合金材料的曲轴箱体静力学模型,用I-DEAS软件对箱体结构进行了分析,指出了箱体开裂的原因,改造了箱体结构,其强度有了显著的提高,制造成本有较大的降低,并验证了原有材料-铝合金的性能.

| Abstract: | The wall thickness and strengthen muscle of motorcycle crankcase box influences its structure intensity directly. The static model of crankcase box of a magnesium alloy material is established by finite element method. The structure is analyzed with I-DEAS, the reason the crankcase box is crazed is pointed out. The structure is rebuilt, the intensity is increased remarkablely, the cost of manufacture is reduced largely. And the capability of a originally material, i.e. aluminium alloy is validated. |
