Method and system for image analysis of gear collision/damage deformation process

Abstract

The invention provides a method for analyzing a gear collision / damage deformation process by using an image. The method comprises the following steps: arranging a strain gage at a tooth root part of a to-be-detected mechanical gear; forming a perforation hole in the tooth part of the gear, arranging laser bi-injection pipes in the positions, where signals can be received, in front of and behind the perforation hole; under the dynamic working condition of the to-be-detected mechanical gear, synchronously acquiring a deformation signal after the strain gage is collided and a laser signal of the laser bi-injection pipes, controlling a high-speed camera to shoot in real time by a processor through real-time monitoring and synchronous trigger control for the deformation signal and the laser signal; and then analyzing the gear collision / damage deformation situation according to the image acquired by the high-speed camera. The high-speed camera is controlled by a synchronously acquiring external trigger system, the dynamic process of the working deformation of the mechanical gear can be recorded in time, through the direct observation and analysis to each frame of image in the dynamic record, the situation of the gear collision / damage deformation process can be obtained clearly and visually, and therefore the reliability is high. The invention further provides a system for realizing the method. The method and the system have the advantages of simple structure, low cost, controllability in operation, and the like.

Description

technical field [0001] The invention relates to a high-speed camera method and equipment for image analysis, in particular to a method for analyzing the process of gear collision or damage deformation by using images, and a synchronously triggered high-speed camera system. Background technique [0002] When large-scale machinery needs gears to couple with each other to drive the rotation, due to reasons such as materials and unreasonable design, the gears are prone to damage or breakage after a period of use. At present, the methods for analyzing the process of gear collision or damage and deformation are mainly to use traditional mechanical diagnosis technology or to use sensors to collect signals for analysis. [0003] However, the traditional mechanical diagnosis technology has the following problems or defects: When performing state detection and fault diagnosis on many mechanical components, the detected components are often not directly observed and measured, and the b...
