摘要/Abstract

摘要： 以双级锤式破碎机为研究对象,考虑销轴所受载荷的加载次序和载荷之间相互作用对销轴疲劳损伤的影响,对Manson-Halford(M-H)非线性疲劳损伤模型进行了修正,并通过试验数据验证了修正后模型的准确性和可靠性;考虑到破碎过程中锤头与销轴之间存在的非线性碰撞接触和物料颗粒对销轴受力的影响,利用MFBD-DEM双向耦合的方法获取了销轴的动态载荷;最后基于修正后M-H模型对销轴进行了疲劳分析。结果表明,与现有模型相比修正后的M-H模型寿命预测的误差最小;基于修正后M-H模型计算得到销轴的最小疲劳寿命为9.918×10⁶次(165 h);利用MFBD-DEM双向耦合方法对双级锤式破碎机等大型破碎设备进行疲劳分析是合理可行的。

Abstract: Taking the double-stage hammer crusher as the research object,considering the load sequence effect and the load interaction effect on pin shaft fatigue damage,the Manson-Halford (M-H) nonlinear fatigue damage model was modified,and the accuracy of the modified model was verified through experimental data. The dynamic load of the pin shaft was obtained through MFBD-DEM bidirectional coupling method,which takes into account the nonlinear collision contact between the hammer head and the pin shaft and the influence of material particles on the force of the pin shaft. Finally,the modified M-H model was used for fatigue analysis of the pin shaft.The results show that compared with the existing model,the modified M-H model has the smallest relative error in the validation of examples. Based on the modified M-H model,the minimum fatigue life of the pin shaft is calculated to be 9.918×10⁶ cycles (165 h). It is reasonable and feasible to use the MFBD-DEM bidirectional coupling method for fatigue analysis of large crushing equipment such as double-stage hammer crushers.
