The results show that the acting planes of the bending moments which cause such a stress field that the maximum stress appears in the crack damage area of the case have an angle range of 0o to 20o against the longitudinal symmetric plane of the car.

• 研究结果表明，最大应力出现在离合器壳体裂纹萌发区域的弯矩载荷，其作用平面相对于汽车纵向垂直平面朝左倾斜约为0o至20o。
