Combination mirror collision and reliability comprehensive test platform

Abstract

The invention provides a combination mirror collision and reliability comprehensive test platform. The combination mirror collision and reliability comprehensive test platform comprises a comprehensive test platform, a hydraulic system and a measure and control system, wherein the comprehensive test platform integrates functional modules such as a retraction jack, an operating handle simulation mechanism and a head collision simulation device, the retraction jack is used for converting the swinging of a combination mirror to the continuous rotation of a driving module, the retraction times and the mechanical variation can be recorded, the collision process of a driver can be actually simulated, the kinematics and dynamics parameters of the entire process can be recorded, and an experimental foundation can be set for researching the reliability, the injury degree and the man-machine system engineering; the hydraulic system drives a head module to collide with the combination mirror at a given speed and acceleration, and the driving acceleration and the collision speed are controllable and adjustable; the measure and control system is used for controlling the test platform in real time, the entire test process is observable, measurable, controllable and adjustable, relevant actions of the driver can be actually simulated, the kinetics and dynamics parameters of the test platform can be collected, the video information can be collected in real time and analyzed in real time, and the control system has advantages of high humanization, high integration and the like.

Description

technical field [0001] The invention relates to a combined mirror collision and reliability comprehensive test platform. Background technique [0002] At present, combined mirrors are widely used in many fields, such as adding combined rearview mirrors to cars. When driving a vehicle, especially when reversing, the driver only needs to adjust the posture of the combined rearview mirror without turning around. You can clearly grasp the information behind the car, which not only improves the comfort of the driver's operation, reduces fatigue, but also increases safety. In civil aviation and other fields, head-up display combination mirrors are generally installed now. If there is no head-up display, the attitude control of the aircraft can only be controlled by observing the instrument data, which greatly increases the workload of the driver and easily makes the driver tired. For example During the landing process of the aircraft, the driver needs to constantly observe the in...

Problems solved by technology

However, the angle of the combined mirror needs to be adjusted during use, so its rotational locking force must conform to ergonomics, that is, the driver should not be too strenuous when turning the combined mirror, nor can the combined mirror be damaged when maneuvering. Danger due to self-holding

Not only that, if the driver suddenly decelerates and leans forward, the forehead collides with the combination mirror, and the combination mirror cannot be unlocked and rotated due to the large locking force, which will cause damage to the human head

Therefore, the setting of the locking force becomes the key to the application of the combined mirror. At present, some research institutes have proposed some testing methods for the locking force, but it is too cumbersome, and it is difficult to ensure consistency, and the service life of the combined mirror shaft is not clearly given, or It is only a reference interval. If fatigue occurs between this reference interval, it is very likely to cause a major accident. If the reference value is too small, it will increase the frequency of maintenance and replacement, resulting in unnecessary waste
