Abstract

The invention discloses a lateral impact testing device for a target object. The device comprises a frame, an impact hammer, an impact hammer height measuring part, an impact hammer height adjusting part, an impact hammer speed measuring part, a secondary collision preventing part and a display screen, wherein the impact hammer height measuring part is composed of a displacement sensor arranged on the frame; the impact hammer height adjusting part comprises a stretchable connecting rod and an electric push rod, and the rear end of the impact hammer is fixed at the other end of the stretchable connecting rod; an electromagnetic relay is arranged on the stretchable connecting rod, and one end of the electric push rod is hinged to the frame while the other end is connected to the magnetic relay; the impact hammer speed measuring part comprises a photogate and a light barrier, the photogate is arranged on a lifting rod and the light barrier is fixed on the impact hammer; and the secondary collision preventing part comprises a rotary shaft, a brake pad, a brake caliper, a brake line and a controller. The device can provide a relatively great impulse, can effectively avoid secondary collision, is convenient to use and relatively low in cost, and can be applied to various lateral impact tests for the target object.

Description

technical field [0001] The invention belongs to the field of lateral impact resistance testing, and in particular relates to a target object lateral impact test device. Background technique [0002] In view of the superior performance of quadruped bionic robots, there has been a research boom in the world in recent years. Research on quadruped bionic robots in my country is still in its infancy. Although several domestic universities have carried out related research work, there is no systematic evaluation standard for the performance of the robots developed. There are few related high-energy impact test equipment, and they cannot be adjusted and displayed quantitatively. Contents of the invention [0003] Aiming at the above-mentioned prior art, the present invention provides a target object lateral impact test device, which fills up the relevant gaps in the prior art, provides a large impulse for the test of the robot's lateral impact resistance, and has quantitative ad...
