Abstract
The invention belongs to the test technology of rod-end elastic bearing performance testing devices and relates to a performance testing device for a rod-end elastic bearing. The rod-end elastic bearing is an important bearing part of a helicopter rotor. Special rigidity testing devices need to be designed for testing performance indexes of the rod-end elastic bearing due to complex loading condition during operation of the rod-end elastic bearing which generates different acting forces through swinging and swaying. Load is applied to the rod-end elastic bearing when the rod-end elastic bearing is under the constant radial compression amount for obtaining the rigidity value. Currently, no rod-end elastic bearing testing device of the above kind exist in the prior art. The invention aims to provide the testing device capable of performing axial rigidity testing of the rod-end elastic bearing.
