摘要
针对目前桥壳分析中采用的简支梁力学模型不能反映钢板弹簧刚度特性对桥壳受力的影响的问题,对基于钢板弹簧约束的某款新开发的驱动桥壳进行了研究。通过驱动桥壳台架试验来验证模拟台架试验的简支梁约束桥壳有限元模型的正确性。在该桥壳有限元模型中装配钢板弹簧来模拟实际工况进行分析,并对引入板簧前后的有限元结果进行比较分析。结果表明,模拟台架试验的有限元分析与台架试验结果误差在10%以内,其有限元模型可信度高;引入板簧前后得到的桥壳应力分布有明显差别;该桥壳的强度和刚度在模拟的实际工况中满足设计要求,为实际工况的桥壳验证提供了参考依据。
To make up the shortcoming that driving axle housing analysis based on simply supported beam theory did not fully reflect the actual working conditions, a newly developed driving axle housing considering leaf spring stiffness characteristics was analyzed with finite element analysis, to check whether its strength and stiffness demanded design requirements. A 3D model and a finite element model of the driving axle housing were established and verified by comparing the results from the bench testing and computing. Based on the model verified, the driving axle housing assembling leaf spring was analyzed with ABAQUS, taking nonlinear stiffness affect of leaf spring into consideration. The results demonstrate that the error rate of the results compared the bench testing with computing is less than 10%, so the model constructed is credible. Distribution of stress ,with comparisons between analysis of driving axle housing assembling leaf spring and that without leaf spring, is distinctly different. Its strength and stiffness meet the design requirements in the actual working conditions simulated. A reference is provided to check driving axle housing in the real vehicle environment.
