摘要:
为了研究造船门式起重机柔性支腿上支承铰的裂纹扩展规律,以300 t×43 m A型双梁造船门式起重机为研究对象,对其进行了带裂纹试验分析。根据上支承铰的工作情况,研究了不同裂纹长度与不同载荷下上支承铰的承力情况,并通过断裂力学理论与扩展有限元的方法计算出了3种裂纹形式下的应力强度因子,分析得出了上支承铰的应力强度因子为Ⅰ-Ⅱ复合型。通过对上支承铰的定量分析,从而得出柔性支腿上支承铰疲劳裂纹扩展的规律,为研究其疲劳寿命提供了理论基础。
Abstract:
For the crack propagation law of the shipbuilding gantry crane flexible leg bearing hinge,the analysis was carried out on style of 300 t×43 m A with a cracking test. Under the working conditions of bearing hinge,the stress conditions of bearing hinge were investigated on different crack lengths and different loads.The stress intensity factor under three kinds of crack by the fracture mechanics theory and extended finite element method was obtained,and it turned out that the stress intensity factor was Ⅰ-Ⅱ compound.Through the quantitative analysis of the bearing hinge,the obtained crack propagation law of the flexible leg bearing hinge provided the theoretical basis for studying its fatigue life.
