Dummy calibration test system capable of being controlled in centralized way

Abstract

The invention provides a dummy calibration test system capable of being controlled in a centralized way. According to the dummy calibration test system capable of being controlled in the centralized way, seven devices of a head part calibration test stand, a neck part calibration test stand, a chest part calibration test stand, a pleural region calibration test stand, a knee part calibration test stand, a foot part calibration test stand and a hip joint calibration test stand are integrated together via control analysis equipment. When calibration is performed on the local joints of a dummy by each calibration test stand, data acquisition and analysis are performed via the unified control analysis device so that consistency of calibration results can be effectively enhanced and the dummy calibration results are enabled to be more accurate. All parts of the dummy can be calibrated by the system so that use is quite convenient.

Description

technical field [0001] The invention relates to the field of passive safety tests of manned vehicles, in particular to a calibration system for dummies used in passive safety collision tests. Background technique [0002] The crash test belongs to the research scope of passive safety, and its purpose is mainly to test the protection ability of the manned transportation vehicles (such as airplanes, ships, automobiles) to the occupants in the event of accidents (such as airplane collisions, ship grounding, car collisions, etc.) . At present, some foreign research institutes have collected the actual data when the accident occurs by installing the acquisition system on the manned transportation vehicle, and used the artificial simulation test device to reproduce the actual data through the collision test in the laboratory, which is used for inspection and Evaluate the ability of a manned transportation vehicle to protect its occupants. [0003] Due to the danger of crash test...

Problems solved by technology

After investigation, there are still application defects in the above patents, among which: the pendulum described in the Chinese utility model patent (patent number: 200320102952) is lifted by manpower, and the lifting height or angle cannot be accurately positioned, which affects the accuracy of the calibration test; and The release mechanism has no protective measures when the power is off, and there are serious safety hazards in the use process; the measurement data of the Chinese invention patent (patent number: 201210159733.0) does not mention the torque, but the torque must be measured in relevant standards and regulations Parameters, through examination, the application example of the present invention is to calculate the torque through the measured data of the force sensor, and as stated in the abstract, the calculation will increase the error; as described in the Chinese invention patent (patent number: 201210159690.6) The pendulum is lifted by manpower, the lifting height or angle cannot be precisely positioned, and the calibration accuracy cannot be guaranteed; the pendulum described in the Chinese utility model patent (201220316887) is automatically lifted by a motor and the angle is controllable, which solves the problem of calibration accuracy, but The release device has no protective measures when the power is lost, and there are serious safety hazards in the process of action

At the same time, the above patent can only calibrate a certain part of the dummy, but cannot uniformly calibrate the whole body of the dummy

In order to complete all the calibration tests of a dummy, it is necessary to use multiple different calibration devices to cooperate with different measurement and control systems. Due to the performance differences of each measurement and control system, the measurement data also have great differences. In this way, the calibration parameters of the dummy Consistency cannot be guaranteed, which will lead to data errors during the use of the dummy, affect the accuracy of the safety detection of manned transport vehicles, cause user operations, and bring security risks to the country and society. Therefore, it is necessary to design a degree of automation High, repeatable, high controllability, easy to operate, good consistency of measurement and control precision dummy body calibration test system
