Impact model emission device for automobile impact experiment

Abstract

The invention discloses an impact model emission device for automobile impact experiment. The impact model emission device comprises a pressure container, an air inflation electrically-operated valve,an emission pipe body, an air guide pipeline, an exhaust electrically-operated valve, an emission mechanism, a positioning mechanism, a groove guide rail and a controller, wherein the air inflation electrically-operated valve is arranged between an air inflation hole of the pressure container and an external air supply system, the emission pipe body is horizontally arranged in the pressure container, one end of the air guide pipeline is connected with a first end of the emission pipe body, the other end of the air guide pipeline is connected to a peripheral surface of the pressure container and an inner cavity of the pressure container, the exhaust electrically-operated valve is arranged between the air guide pipeline and the emission pipe body, the emission mechanism is arranged in the emission pipe body, the positioning mechanism is arranged on the emission mechanism, the groove guide rail is arranged on front ground of the pressure container, and the controller is connected with the air inflation electrically-operated valve and the exhaust electrically-operated valve. The impact model emission device is simple in structure and small in occupancy space and is convenient to operate and is easy to promote.

Description

technical field [0001] The invention relates to the technical field of automobile impact test devices, in particular to an impact model launching device for automobile impact tests. Background technique [0002] At present, passenger cars are generally equipped with restraint systems such as airbags, and whether the restraint system detonates in an accident is controlled by the ACU (Electronic Control Unit). In order to avoid false detonation in non-collision accidents, a large number of misuse tests are usually done in the process of determining the ACU algorithm, including two-wheeler impact tests near the position of the two-wheeler impact sensor, shopping cart impact tests, etc. In addition, with the continuous deepening of the research on VRU safety technology, it is also necessary to conduct a joint collision test between a two-wheeled vehicle and a motor vehicle, that is, a moving motor vehicle collides with a moving two-wheeled vehicle. [0003] For the above-mentio...
