Description

Technical Field

[0001] The invention belongs to the technical field of hydrodynamic testing and relates to a water entry and exit testing system for an amphibious vehicle with continuously adjustable slope. Background Art

[0002] In recent years, the application of amphibious vehicles has gradually expanded, moving from inland areas to the intersection of land and sea. Amphibious vehicles are now required to function in these environments. Amphibious vehicles, capable of both water and land navigation, have broad adaptability, significant practical applications, and promising development potential. Consequently, their development and performance verification methods are gaining increasing attention. During amphibious vehicle performance verification, the ability to enter and exit water and climb grades is a key verification function, directly determining the vehicle's landing capabilities.

[0003] The current shortcomings of amphibious vehicle entry and exit verification technology are as follows: (1) The traditional verification method for amphibious vehicles is to use lake waters to conduct performance verification tests. The test waters are far away and it is inconvenient for vehicles to pass through; (2) In outdoor lake waters, it is necessary to temporarily build angle slopes with different slopes to conduct climbing ability verification tests. In order to ensure the safety of the verification process, the slope is generally verified from a small angle slope to a large angle slope, which takes a long time to build, is costly, and has low efficiency; (3) The outdoor angle slope is temporarily built with sand and gravel and cannot be continuously adjusted. After driving for a period of time, the slope angle of the angle slope will change to a certain extent. Summary of the Invention
