Deflection Prediction for Large Tonnage Gantry Crane Girder Midspan Base on Diagram Multiplication Method

  • 摘要: 门式起重机承受额定载荷时主梁跨中的下挠值是门式起重机整机试验的最重要检测指标。对于大吨位门式起重机整机实验时,实验砝码现场准备往往十分困难,甚至无法进行整机实验检验。针对门架结构考虑了支腿弯矩对主梁挠度影响的情况,推导出集中载荷在主梁L/2、L/3、L/4处作用时的挠曲线方程,通过测量小载荷分别在L/2、L/3、L/4处作用的主梁下挠值,求得主梁和两侧支腿的实际惯性矩,从而可以预测门式起重机额定载荷时主梁的下挠度。主梁三位置小载荷实验法为预测大吨位门架结构主梁挠度提供了实用有效的方法。
