Description

Technical Field

[0001] The invention belongs to the technical field of multimodal detection, and in particular relates to a multimodal nondestructive detection system and method for a bow and arrow releaser. Background Art

[0002] As a key component of archery equipment and related equipment, the quality and performance of the bow and arrow release device are directly related to the safety of the user and the archery effect. The traditional bow and arrow release device detection method has many limitations:

[0003] Single detection method: In the past, most of the detection methods relied on single detection methods, such as visual inspection or simple mechanical performance test. Visual inspection is limited by the resolution of human eyes and subjective judgment, and it is difficult to detect small defects or potential damage; simple mechanical performance test can only obtain limited mechanical parameters, and cannot fully evaluate the performance of the release device under complex working conditions.

[0004] Inability to conduct comprehensive testing: For the trigger mechanism of the releaser, traditional testing is difficult to take into account the comprehensive testing of travel displacement, strain change, appearance, etc. For example, the strain inside the trigger mechanism is easily overlooked in traditional testing, which is crucial for judging the reliability of the trigger mechanism. Minor strain anomalies may gradually develop into serious faults during long-term use, affecting the normal use of the releaser and even endangering the safety of the user.

[0005] Therefore, it is of great practical significance to develop a multimodal nondestructive testing system and method that can integrate multiple detection methods to comprehensively and accurately detect the performance and defects of bow and arrow release devices. Summary of the invention
