Research on eccentric force of sucker rod upsetting process 抽油杆平锻工艺的偏心力研究
This paper researched the transmission control technology, pressure plate technology, sucker control technology and inert gas filling control technology in the process of insulating glass production line separately. 然后分别对中空玻璃生产过程中玻璃传输控制技术、中空玻璃板压技术、中空玻璃合片工艺中的吸盘控制技术以及惰性气体填充技术进行分析和研究。
The Study on Rotating Slender Beam in Cylinder derive from oil drilling project, it is great significance to structural optimization design of sucker rod, drill string and the development of process parameter optimization. Rotating slender beam is abstracted mechanical model from the oil drilling. 圆筒内旋转细长梁问题来源于石油钻采工程中,开展这项研究对石油钻采工程中的抽油杆柱和钻柱的结构优化设计、工艺参数优选等技术发展具有重要意义。
The sucker rod is an elastomer which is more than one kilometer long, it is acted upon by many kinds of loads during its working process. 抽油杆作为一根上千米的弹性体,在工作过程中受到多种载荷的作用。
In this thesis, started from the structural characteristics of sucker rod, sucker rod upsetting forming process is analyzed and sucker rod forging process scheme is programed. 本文从抽油杆的结构特点入手,结合抽油杆的镦锻成形过称,分析抽油杆的镦锻工艺过程的损伤机理。
