Abstract

The invention discloses an air cannon high-speed impact test tool for a composite material plate and an application method thereof. The test tool comprises a test base, a test piece placement platformand an overturning buckle plate; a sliding rail is arranged at the bottom of the test base, the test piece placement platform is rotatably arranged on the test base, and a first test piece test window is formed in the test piece placement platform; runway grooves are formed in the two sides of the first test piece testing window, test piece fixing assemblies are arranged on the runway grooves ina sliding mode, one end of an overturning buckle plate is hinged to the test piece containing platform, the other end of the overturning buckle plate is detachably connected with the test piece containing platform, and a second test piece testing window is formed in the overturning buckle plate. A pressing frame is arranged on the inner side of the overturning buckle plate. The test tool is simplein structure and convenient to operate, the impact angle and the impact position of the test piece can be conveniently adjusted, a new test piece can be conveniently replaced, flexible posture adjustment of the test piece is achieved, and the test precision and the test efficiency of the test piece are improved.

Description

technical field [0001] The invention relates to the technical field of high-speed impact testing of composite materials, in particular to an air cannon high-speed impact testing tool for composite material plates and an application method thereof. Background technique [0002] Composite materials are widely used in aerospace, high-speed trains, automobiles and other fields due to their high specific strength, high specific stiffness, fatigue resistance, and corrosion resistance. During the use of composite materials, they are often impacted by some foreign objects, for example, the impact of flying birds, sand and stones and other foreign objects encountered during the running of high-speed trains. Therefore, the research on the high-speed impact performance of air cannons for composite materials has attracted much attention, and the design and use of impact test tools play an important role. [0003] At present, there is no unified standard for testing tooling for high-spe...
