The rolling linear guide power damper reliability testing platform comprises a temperature -humidity testing tank, a damper working table, horizontal iron, an X-direction feeding device, a Y-direction feeding device, a damper loading unit support part, a piezoelectric ceramic loading part, a damping property detection part and an automatic control part, wherein the lower end of the damper loading unit support part is fixed on the horizontal iron; the upper end of the X-direction feeding device is fixed with the damper working table; the lower end of the X-direction feeding device is fixed with the horizontal iron; two ends of a roller screw rod are fixed on the damper loading unit support part; a Z-shaped plate is partially matched with the damper loading unit support part; the piezoelectric ceramic loading part is fixed below the Y-direction feeding device; a three-direction accelerator, a pressure sensor and an automatic control part are connected. By adopting the rolling linear guide power damper reliability testing platform and the testing method, typical working situation loading of rolling linear guide power dampers of different models can be simulated.

Description

technical field [0001] The invention belongs to the technical field of reliability testing of mechanical parts, and in particular relates to a reliability test bench and a test method for a rolling linear guide rail auxiliary damper capable of simulating typical working conditions on different types of rolling linear guide rail auxiliary dampers. Background technique [0002] With the continuous development of modern manufacturing technology and the continuous improvement of positioning accuracy, feed accuracy and guiding accuracy of mechanical transmission mechanisms, traditional guiding mechanisms have brought about tremendous changes. With its unique characteristics, rolling linear guides have gradually replaced traditional sliding linear guides and have been more widely used in industrial production. Due to the limited point and surface contact between the bottom surface of the linear guide and the rolling elements, the defect of poor vibration damping performance of the...
