Drop and crash safety test machine

Abstract

The invention relates to a drop and crash safety test machine which is characterized by comprising a workbench, a computer control system and a loader, wherein the workbench consists of a base and a test sample mounting seat arranged on the base; the computer control system comprises a computer with control software and a programmable controller; the loader mainly comprises an oil pump, an electro-hydraulic servo valve, an oil cylinder and a loading connector; the oil pump is used for supplying oil to the electro-hydraulic servo valve, and the electro-hydraulic servo valve is used for receiving control signals output by the programmable controller; and the oil cylinder is used for simulating a drop and crash stress environment applied to a test sample through the loading connector so as to verify whether the mechanical strength and the rigidity which are fixed and supported by airborne equipment in a drop and crash state meet the requirement of drop and crash safety or not. Beginning from a failure mechanism, special test equipment suitable for airborne (vehicle-borne) equipment such as airplanes, vehicles, ships, and the like for carrying out drop and crash or collision and crash safety tests is designed, thereby the defects brought by adopting segmented tests because no special test equipment exists at present are overcome.

Description

technical field [0001] The invention relates to a testing machine, in particular to a safety testing machine for crashing or colliding of aircraft, vehicles, ships and other vehicles, and belongs to the technical field of testing equipment. Background technique [0002] Planes, vehicles, and ships sometimes encounter unfortunate incidents such as crashes and collisions. In order to ensure that the occupants can escape under a certain accident intensity, there are certain requirements for the structural strength of the occupant seat and its surrounding equipment, so as to prevent some equipment or parts from falling off the mounting bracket or freeing the occupants due to crashes or collisions. Or excessive deformation and displacement will affect the work of the lifesaving system. The crash safety test is a test used to verify whether these equipment or parts will fall off or dissociate from the mounting bracket in the event of a crash or collision, endangering the safety o...
