Abstract

The electrical mechanical energy-storing automobile impact test apparatus has motor, flywheel connected via a belt pulley mechanism to the motor, rotating drum connected via an electromagnetic clutchto the flywheel, guiding screw bolt mechanism connected via a chain wheel mechanism to the rotating drum, spiral track on the outer surface of the conic rotating drum and steel cable on the rotating drum; and a control and detection system comprising computer, detector, A / D converter, D / A converter, force sensor, acceleration sensor, optoelectronic sensor and solenoid valve. The rotating drum is connected to the tested automobile and the braking winding engine via the guiding screw bolt mechanism and the guiding pulley combination. The present invention has the advantages of precise control, precise measurement, capability of maintaining constant acceleration of the tested automobile, simple structure, low cost and wide 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...
