AI Technical Summary
Technical Problem
Existing technologies lack methods for assessing the performance degradation and fatigue life of air defense door hinge mechanisms under long-term dynamic loads, leading to quality control and safety hazards.
Method used
A fatigue resistance testing fixture for the hinge mechanism of a civil defense airtight door was designed, including a wall, a drive unit, a connection unit, and a control system. Repeated opening and closing simulation is achieved through motor-driven gear transmission, and automated testing is carried out in combination with an intelligent control system.
Benefits of technology
It enables real-world simulation and automated testing of hinge mechanisms, provides quantitative data support, and improves quality testing standards and equipment reliability.

Abstract
The invention relates to a tool and a method for detecting fatigue resistance of a civil defense air-tight door hinge mechanism, and the tool comprises a wall body which is vertically provided with a first installation pedestal and a second installation pedestal at an interval; the driving unit comprises a motor and a gear transmission mechanism driven by the motor, and the motor is fixedly mounted on the first mounting base or the second mounting base; the connecting unit comprises a shaft sleeve connected with the power output end of the gear transmission mechanism, and the shaft sleeve is detachably connected with a rotating shaft of the detected hinge mechanism; wherein the fixed end of the detected hinge mechanism is mounted on the first mounting base or the second mounting base, and the movable end of the detected hinge mechanism is used for being connected with a simulated closed door leaf; and the driving unit is configured to drive the rotating shaft to do reciprocating rotation motion through the connecting unit so as to drive the simulated closed door leaf to be opened and closed repeatedly. The device is reasonable in structure and convenient to operate, and can truly simulate the repeated opening and closing working condition of the civil air-tight door.
