Water brake system for aerodynamic experiment kinetic energy output

Abstract

The invention provides a water brake system for aerodynamic experiment kinetic energy output. The water brake system comprises a brake mechanism, a connecting mechanism, a stroke return mechanism, a water cycle system and a control system. The brake mechanism comprises a brake cylinder, a brake piston rod, a piston assembly and an end cover; damping holes with different sizes are formed in the upper end of the inner wall of the brake cylinder according to a certain rule; the connecting mechanism comprises a rubber pad, a connecting box body, a supporting trolley and a guide rail; the rubber pad of the connecting box body is used for preventing the box body from deforming during collision; the stroke return mechanism comprises a gear, a rack, a ball bearing guide rail, pushing angle iron, a motor and a speed reducer; and the water cycle system comprises a water blocking box, a water pump, a water suction sump, a pipeline, a one-way valve and a stop valve. According to the brake system, the pushing piston rod used for kinetic energy output can be effectively subject to braking and stroke return, provided brake force is large, the needed brake distance is short, and the water brake system is used for a kinetic energy output test table for high-speed and large-mass objects.

Description

technical field [0001] The invention relates to a brake system, in particular to an aerodynamic test kinetic energy output water brake system. Background technique [0002] The aerodynamic test kinetic energy output test bench uses the aerodynamic system to realize the impact test of various products and achieve the transient mechanical environment of the test at a relatively low cost. High-speed impact can be used to analyze the material characteristics of different stones in geological engineering; the kinetic energy output test can be used to detect whether the mechanism of medical equipment in important medical research is reasonable and reliable; the kinetic energy output test can be used to check whether the building meets earthquake resistance and impact resistance ability and so on.
