rivet stem meaning in Chinese

铆钉杆

Carry on a large amount of experiment and analysings , the result of calculation of designing has been verified , the error of designing and computing has been revised , the physical dimension of the rivet has been confirmed finally . combine the real working condition of the factory the difficulties that the rivet stem and the locking collar are difficult to process are solved , a series of feasible technology schemes are made finally . according to the designing and of the test of the blind rivet , consult the relevant standards of u . s . a . , the relevant aviation industrial standards which lay the foundation for the popularizaion and application of the rivet are compiled
本文通过系统分析及计算，突破了铆钉抽铆成形、剪断环及时被剪断、芯杆到位及时拉断等一系列技术难点，确定了设计方案，运用有限元方法对机械锁紧鼓包型抽芯铆钉进行了强度分析：制定了试验方案，验证了设计计算结果，修正了设计计算所造成的误差，确定了铆钉的结构尺寸；结合工厂的实际生产条件，解决了钉杆和锁圈难以加工的困难，制定出?系列可行的工艺方案：根据设计及试验结果，参照美国的相关标准，编制了系列航空工业标准，为机械锁紧鼓包型抽芯铆钉的推广应用打下了基础。
