摘要
采用MSC.Marc有限元软件建立了分析模型,分析了板件中热应力分布及其随时间变化对螺栓预拉力的影响,研究了不同梁高与螺栓数量的螺栓群承载力变化规律,并对螺栓群补拧区域提出了几点建议。
This paper established the analysis model using finite element software MSC. Marc,analyzed the influence of component plate thermal stress distribution and its variation with time to bolt pretension,researched the bolts group bearing capacity variation law of different beam height and bolt number,and put forward some suggestions for bolts group reinforcing screw region.
