English translation for "大开孔"

large openings

Example Sentences:

	1.	Finite element analysis of pressure vessle with off - angle large opening 压力容器斜大开孔的有限元应力分析
	2.	Stress concentration on thin cylindrical shells with large non - circular openings 圆柱壳非圆大开孔的应力集中研究
	3.	Experimental study on stain and stress of big - hole sealing head in fire - tube heating boiler 火筒加热炉大开孔封头应力应变试验研究
	4.	Finite element analysis of the reinforcement structure strength of pressure vessel with large opening 压力容器大开孔补强结构强度有限元分析
	5.	Finite element analysis and stress test for opening tubing connection on pressure vessels 内压容器壳体上矩形大开孔接管三维有限元分析与强度计算
	6.	Compared with large opening without nozzles , the stress concentrations around the junction are sharply reduced because of the nozzles 与未带接管的大开孔结构相比，接管的添加大大降低了孔周边的应力集中。
	7.	That is , when a large opening exists on the cylindrical shell , high local stresses will present in the opening nozzles . so it is not safe to design by equi - area method of reinforcement 工程结构中常常要用到各种大开孔的结构，超出了常规设计的经验公式的适用范围，只能依靠实验研究，进行对比分析设计，这样会导致成本提高和设计周期延长。
	8.	Present the experimental research carried out on strain and stress by applying the resistance strain surveying technique to the big hole sealed heads in the new fire - tube heating boilers with the laws of strain and stress distribution obtained and allowable working pressure given because there is no applicable standards or specification for calculating the strength of crude oil heating boiler heads perforated by densely distributed big - holes , which , to a certain extent , hampered the further development of crude oil heating boilers in china , and concludes from experimental results that strain and the stress of circumference are fairly large near the edge of big - hole , and the cross ribs enhance strength of sealed head to a certain degree 油田火筒加热炉密集大开孔封头的设计计算，因没有相应的强度计算标准在一定程度上限制了我国油田火筒加热炉技术的发展.采用电阻应变测量技术，对新型火筒加热炉大开孔封头进行了应力应变试验研究，得到了封头的应变和应力分布规律，给出了大开孔封头允许的工作压力.试验结果表明，大孔边缘圆周处应力应变较大，十字筋板对封头有一定加强作用
