摘要
为提高门式刚架的使用保障,需要对门式刚架进行探伤与维护。对于门式刚架机器探伤系统,几何因素对机器探伤系统的运行方案的影响还没有得到很好的研究。为此目的建立了门式刚架模型,首先分析机器探伤系统加载在不同位置时对门式刚架的立柱和横梁连接的刚结点产生的弯矩,然后在这个状态下进行分析,考虑几何因素,分析几何因素对门式刚架杆件受压与受拉特性的影响;最后对不同几何比例的门式刚架模型的计算结果进行比较并得到规律。算例分析表明,在进行门式刚架的受力分析中,几何因素—主要是几何比例,对进行机器探伤系统加载的影响是比较显著的。在加载机器探伤系统时,爬升系统的运行速度应进行细致的方案设计。
In order to improve the work capacity of door frame, investigations are carried out to detect door frame and to maintain its capacity. It indicates in this paper that the study should be carried out to investigate the influence of the geometry on the damage detection scheme of the machine. The models have been introduced to analyze the moment of the joint if the damage detection system is applied at different points. The study is carried out to analyze the influence of geometry on the member bars of the door frame. The studies are carried out to compare the results of models of different door frames. It appeared that the geometry in the loading of damage detection machine has moderate influence on internal forces of the door fame. The study should be carried out to investigate the climbing speed of climbing system as a design guideline.
