驱动桥壳在实际行驶过程中由于长期受到交变循环载荷的作用,
发生疲劳破坏的可能性较大。为了判断某商用车轮边电机电驱动桥的驱动桥壳在设计时是否满足疲劳寿命的要求,建立了驱动桥的三维模型和有限元模型。首先,对其进行惯性释放分析,得出其静强度、刚度满足要求。其次,基于nCode DesignLife软件,使用名义应力法,结合材料的

曲线和疲劳加载曲线,采用新的汽车行业标准对其在垂直弯曲疲劳、制动疲劳和横向疲劳多工况下的疲劳寿命进行了预测。结果发现,驱动桥壳在制动疲劳和横向疲劳工况下的疲劳寿命不满足标准中的要求,须对其进行结构优化。最后,对驱动桥壳进行了加筋优化处理。结果表明,优化后的驱动桥壳在最大冲击工况下最大应力减小了95.8 MPa,最大变形减小了1.064 mm,且在3种疲劳工况下的最低疲劳寿命分别提升了107.6、28.9、49.7万次,均超出了标准中的要求,证明了驱动桥壳结构优化的可行性,有效缩短了研发周期,并降低了研发成本。
In the course of real operation
the drive axle housing is likely to undergo fatigue failure due to prolonged exposure to cyclic alternating loads.To determine whether the drive axle housing of a commercial vehicle’s wheel-side electric motor complying with fatigue life requirements at the design stage
a three-dimensional model and finite element model of the drive axle were established. Firstly
an initial inertia release analysis was performed,indicating that its static strength and stiffness met the requirements.Secondly
based on this foundation,utilizing nCode DesignLife software
using the nominal stress method in conjunction with the material’s
S

N
curve and fatigue loading curve
a new automotive industry standard was employed to predict the fatigue life of the housing under multiple conditions,such as vertical bending fatigue
braking fatigue and lateral fatigue.The results revealed that the fatigue life of the drive axle housing under braking fatigue and lateral fatigue conditions did not meet the requirements set out in the standard
necessitating structural optimization. Finally
reinforcement optimization was performed on the drive axle housing. The results show that
through optimization,the maximum stress of the drive axle housing is reduced by 95.8 MPa and the maximum deformation is decreased by 1.064 mm under the maximum impact conditions.Additionally
the minimum fatigue life under three different fatigue conditions is improved respectively by 1.076 million cycles
289 000 cycles
and
497 000 cycles
exceeding the requirements stated in the standards.This validates the feasibility of optimizing the drive axle housing structure
effectively shortening and reducing the research and development cycles and associated costs.
