Abstract

The invention discloses an impact test bench for an automobile event data recording system. The impact test bench comprises an EDR main body cabinet, and an EDR experiment operation cabinet, a transformer cabinet and an electric control cabinet which are arranged in the EDR main body cabinet, and a groove type linear motor is arranged in the EDR experiment operation cabinet; the impact test benchfurther comprises adapter plates which are located on the two sides of the groove type linear motor, EDR installation platforms are arranged on the adapter plates, and EDR modules are installed on theEDR installation platforms; the impact test bench further comprises a display bracket which is mounted on one side of the top of the EDR main body cabinet and is positioned on one side of the EDR experiment operation cabinet and the electric control cabinet; and the impact test bench further comprises a left fan opening and a right fan opening which are formed in the top of the electric control cabinet. The beneficial effects of the invention are that the high-performance dynamic response capability and acceleration of the linear synchronous motor are utilized to achieve the full-closed-loopprecise control of the output thrust and current loop, thereby achieving the high-precision reproduction of the acceleration, speed and displacement of a shock waveform in an impact process; and meanwhile, the device has the excellent performances of low power energy consumption, small occupied area, short test interval time, high reproduction precision, strong controllability and the like.

Description

technical field [0001] The invention relates to the technical field of impact test equipment, in particular to an impact test bench for an automobile event data recording system. Background technique [0002] EDR: Event Data Recorder, refers to the car event data recording system, which is used to record the key data of the car's operation (speed, ABS status, seat belt status, etc.) The early EDR is usually integrated with the airbag controller AirbagECU. After a collision, the data of the airbag module is analyzed to restore the collision state of the vehicle. However, in view of the complexity of vehicle collision events, the data recorded by the airbag EDR module cannot fully and accurately reflect the accident state of the vehicle, so it is necessary to study the data required by EDR and formulate corresponding national standards. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [000...
