Problems solved by technology

[0003] The patent with the authorized notification number of CN 210051517 U discloses a durability test device for a damper, which includes: a movable frame; a fixed plate, the top and bottom of which are respectively fixed to the movable The top and bottom of the inner wall of the frame; the first test structure, the first test structure is arranged on one side of the inner wall of the movable frame, the first test structure includes a sliding plate, and the two sides of the sliding plate slide respectively It is connected to one side of the inner wall of the movable frame and one side of the fixed plate; although this device can be used to test the durability of the damper, it cannot test multiple dampers at one time during the testing process. The durability test efficiency of the damper is low; therefore, a durability test device for the damper is now provided to solve the above technical problems

Abstract

The invention discloses a damper durability test device, which relates to the technical field of damper testing, and comprises a test frame, on which a rotating disk is installed for rotation, and several vertically arranged fixed sleeves are evenly distributed on the rotating disk, for testing An adjustment wheel is installed at the bottom of the frame, and a rotating traction mechanism is installed between the adjustment wheel and the arc-shaped clamping block. An adjustment mechanism is provided on the guide rod, and the adjustment mechanism is used to drive the push wedge to deflect relative to the test frame. A translation mechanism is installed on the frame, and the translation mechanism is used to drive the thrust wedge to slide and translate relative to the rotating disk; the present invention conducts the durability test of the damper through the thrust of the thrust wedge and the end of the damper, and the adjustment mechanism can The inclination of the wedge surface of the thrust wedge can be flexibly adjusted to realize the flexible adjustment effect on the axial and lateral forces of the damper according to the test requirements, and to simulate the force of the damper under actual working conditions, and to realize multiple Damper durability test under various working conditions.

Description

technical field [0001] The invention relates to the technical field of damper testing, in particular to a damper durability testing device. Background technique [0002] The damper is a device that provides movement resistance and consumes movement energy. Various dampers have been used in aerospace, aviation, military, guns, automobiles and other industries to reduce vibration and energy dissipation. At present, it has begun to gradually Transfer these technologies to structural engineering such as buildings, bridges, and railways. [0003] The patent with the authorized notification number of CN 210051517 U discloses a durability test device for a damper, which includes: a movable frame; a fixed plate, the top and bottom of which are respectively fixed to the movable The top and bottom of the inner wall of the frame; the first test structure, the first test structure is arranged on one side of the inner wall of the movable frame, the first test structure includes a slidin...
