Abstract

An electromechanical energy storage type automobile crash test device, which is connected by a motor through a pulley transmission mechanism to a flywheel, the flywheel is connected to a rotating cylinder through an electromagnetic clutch, and the rotating cylinder is connected to a screw guide mechanism through a sprocket transmission mechanism. The outer surface of the conical rotating cylinder is There is a spiral track, and a steel wire rope is installed on the drum to connect the test vehicle through the screw guide mechanism and the guide pulley group, and then connected to the braking hoist; it is composed of a computer, a detector, an A / D multiplexer, a D / A multiplexer, A force sensor, an acceleration sensor, a photoelectric sensor and a plurality of electromagnetic valves are electrically connected to form a control and detection system. The invention has the advantages of accurate control, high test precision, can maintain the acceleration of the test vehicle basically constant, simple structure, low cost and strong adaptability.

Description

Technical field: [0001] The invention relates to an automobile collision test device for detecting and evaluating the safety performance of automobiles, in particular to a motor-driven mechanical energy storage type automobile collision test device. Background technique: [0002] Existing automobile crash test device has electric traction type, liquid or gas launching type, mechanical type. The liquid or gas launch type test device is powered by hydraulic pressure or air pressure, and is composed of hydraulic cylinder or cylinder and piston as the driving device. It is expensive, and the gas launch type has a short traction stroke and cannot achieve constant acceleration. It has certain applications. Limitation: The mechanical test device uses rubber rope or spring to release energy when it is stretched or compressed as power to drive the test vehicle, or to use the power traction test vehicle with free falling weights. This type of test device is simple in structure and che...
