摘要:
通过试验分析,研究了钢吊车梁在滚动吊车轮压作用下腹板上部区域的局部扭转应力、局部挤压应力、最大剪应力等的变化规律,提出了相应的计算公式。根据实际冶金厂房中钢吊车梁破坏的现场资料,验证了水平的最大剪应力循环是导致吊车梁上部区域早期疲劳破坏的主要原因,提出了重级工作制钢吊车梁上部区域疲劳强度的验算公式。
Abstract:
Through experimental analysis, this paper researches the regularities of local torsional stress, local compression stress, maximum shearing stress and so on in the upper part of web of steel crane runway girders under the roiling pressure of crane wheels, and presents corresponding calculation formulas. According to site fatigue damage of steel crane runway girders in actual metallurgical factory buildings, this paper proves that the horizontal alternating maximum shearing stress is the main factor which causes early fatigue damage in upper part of steel runway girders, and presents a calculation formula for the fatigue strength of upper part of heavy-duty steel runway girders.
