延长技术装备零部件的使用寿命是节约物质资源和保证各种机器和机械长期运转而不修理的巨大潜力。对于普遍应用而又极重要的机车车辆零件,特别是客车吊挂装置用圆簧来说。延长寿命是极迫切的任务。运用数据表明,目前客车悬挂装置系统用的弹性元件的结构和制造工艺还不能保证所要求的寿命,弹簧过早损坏,而且主要是断裂。为了判定断裂特性,曾对КВЗ—ЦНИИ1、2型和КВЗ—5型转向架的圆簧技术状
Extending the useful life of technical equipment components is a great potential for saving material resources and for ensuring the long-term operation of various machinery and machinery without repair. For the most commonly used and extremely important parts of rolling stock, especially for passenger car suspension device for the spring. To extend life expectancy is an extremely urgent task. The use of data shows that the current structure and manufacturing process of the elastic elements used in the suspension system of passenger cars can not guarantee the required life expectancy, the premature failure of the spring, and mainly the fracture. In order to determine the fracture characteristics, once on the КВЗ-ЦНИИ1,2 type and КВЗ-5 bogie spring technology
