| 摘 要： | 随着轨道车辆运行速度的提高、车辆载荷的增加及其焊接结构形式的复杂化,车辆的承载状况变得十分复杂.热点应力方法作为一种结构疲劳强度评定方法,其计算结果更接近于焊件实际应力,但尚未在轨道车辆结构疲劳评定中广泛应用.本文以热点应力方法为理论基础,分析、比较不同有限元模型与外推公式对热点应力计算结果的影响,计算不同载荷形式下的...

| Abstract: | Along with raising of train speeds,increasing of car loads and complicating of welded structures,the car-load-bearing conditions are becoming more and more complex.As a kind of structure fatigue strength evaluation method,the hot spot stress(HSS) method can get good calculation results that are more closer to real stresses of weldments though the method hasn't been widely applied in the fatigue strength evaluation of railway cars.In this paper,the hot spot stresses are calculated with different finite eleme... |
