Li Zihua, Cao Yu

ABSTRACT: As the development of China’s high-speed railway, the production of rail cars, locomotives, as well as the components, such as rail passenger car locks, increased significantly. It is vital that their operation is reliable, which is related to the safety of the whole railway system. A new durability test device for rail passenger car locks is researched and developed in this paper, with which the durability test of rail passenger car locks can be carried out automatically. Practicality of this device is validated, and it turns out that the device is compact, highly efficient, suitable for various types of locks and is of simple operation.
