Abstract

The invention discloses a ground mechanical performance testing device for underwater operation of a crawler vehicle, comprising an experimental bench support, a transverse shear stress generating unit, a vertical subsidence pressure generating unit, a sediment simulation unit, a crawler shoe motion simulation unit and a test unit. The experimental bench support, the sediment simulation unit and the track shoe motion simulation unit are used to simulate the underwater operation conditions of the tracked vehicle. The transverse shear stress generation unit and the vertical subsidence pressure generation unit generate shear stress and subsidence pressure. The test unit determines the ground mechanics between the track shoes and the sediment. The invention can improve the passing performance of the tracked vehicle during underwater operation by changing the structural parameters of the track shoe and the road condition of the sediment under the experimental environment condition.

Description

technical field [0001] The invention belongs to the field of crawler vehicle operation, in particular to a ground mechanical performance testing device for the underwater operation of the crawler vehicle. Background technique [0002] With the continuous acceleration of urbanization and the impact of global climate change, cities in my country, especially coastal cities, are facing the risk of waterlogging. According to the survey, in recent years, urban rainwater waterlogging events have occurred frequently in my country, and the frequency of waterlogging has shown a rising trend. Urban waterlogging will inevitably cause problems such as inland river rock or sediment deposition, narrowing and shallow river channels, etc., which limit the function of inland river drainage during flood season, which not only threatens the safety of public life and property, but also seriously affects the national or regional economy. River dredging is an important measure to quickly restore ...
