摘要:
针对列车吊挂螺栓的理论计算结果存在较大误差,难以满足吊挂螺栓服役时间分析需要的问题,开展吊挂螺栓加速疲劳仿真模拟和试验研究,结合研究结果建立了疲劳寿命线性回归模型。首先,开展吊挂螺栓疲劳仿真试验,对吊挂螺栓进行静力学分析和疲劳分析; 然后,设计试验夹具以验证夹具性能,并开展疲劳试验,获取不同交变轴向力下的循环次数; 继而,基于Goodman修正理论方程计算不同交变轴向力下的循环应力; 最后,根据循环应力-循环次数双对数线性回归模型对疲劳寿命模型进行求解。结果表明,在动载荷为65 kN、70 kN、75 kN、80 kN、85 kN的情况下,吊挂螺栓加速疲劳试验的平均循环次数分别为86 703、77 190、68 414、62 084、56 105; 求解的疲劳寿命模型为NS1.632=2.538×1018。提出的模型和方法可为吊挂设备螺栓的疲劳试验和吊挂螺栓修程优化提供参考。
Abstract:
In response to the problem that the theoretical calculation results of train suspension bolts have significant errors and are difficult to meet the needs of service life analysis, accelerated fatigue simulation and experimental research were conducted on suspension bolts. Combined with the research findings, a linear regression model for fatigue life was established. Firstly, fatigue simulation experiments were carried out on suspension bolts, performing static analysis and fatigue analysis. Then, an experimental fixture was designed to verify its performance, and fatigue tests were conducted to obtain the number of cycle times under different alternating axial forces. Subsequently, the cyclic stresses under different alternating axial forces were calculated based on the Goodman correction theoretical equation. Finally, the fatigue life model was solved according to the double logarithmic linear regression model of cyclic stress versus the number of cycles. The results indicate that under dynamic loads of 65 kN, 70 kN, 75 kN, 80 kN, and 85 kN, the average numbers of cycles in the accelerated fatigue tests for suspension bolts are 86 703, 77 190, 68 414, 62 084, and 56 105, respectively. The derived fatigue life model is NS1.632=2.538×1018. The model and method proposed can provide a reference for fatigue testing of suspension equipment bolts and offer guidance for optimizing the maintenance procedures of suspension bolts.
