门式起重机带缺陷柔性支腿的静力学分析
摘要
Abstract
With the current flexible leg of 300 t ×43 mA gantry crane as a study object, the models of three cracking defects on the flexible leg are built.By finite element software, the stress and strain conditions affected by cracks in differ-ent positions and different opening directions are analyzed in the paper , which shows that the crack at the leg intersection and parallel to the direction of reinforcing ring is the most harmful to the leg , which provides new method and theoretic ba-sis for site detection and safety evaluation of the gantry crane.关键词
