Abstract

The invention discloses a target object lateral impact test device, which 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 impact preventing part and a display screen; the impact hammer The height measuring part is composed of a displacement sensor arranged on the frame; the height adjustment part of the impact hammer includes a telescopic connecting rod and an electric push rod, and the rear end of the impact hammer is fixed on the other end of the telescopic connecting rod; There is an electromagnetic relay, one end of the electric push rod is hinged to the frame, and the other end is connected to the electromagnetic relay; the impact hammer speed measurement components include a photoelectric door and a light baffle, the photoelectric door is set on a lifting rod, and the light baffle is fixed on the impact hammer; Secondary impact prevention components include rotating shafts, brake discs, brake calipers, brake lines and controllers. The invention can provide relatively large impulse, can effectively avoid secondary impact, is convenient to use, and has low cost, and can be used for lateral impact tests of various targets.

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...
