Embodiment １

[0034] figure 1 Shown is a child dummy calibration table for a car crash test, including a support stand 19, a measuring mechanism and a control mechanism set on the support stand 19, and a data acquisition mechanism under the control of the main program. in:

[0035] (1) The support stand 19 has a vertical cervical and lumbar calibration surface 16, and a horizontal abdomen and neck calibration surface 11, on which an abdominal spacer positioning device is provided, and an adjustable vertical height and Guarantee the abdominal calibration platform 9 of its horizontal display. The abdomen calibration platform 9 is flat, and is used to apply downward pressure to the dummy abdomen block 10 and record the amount of compression deformation. The abdomen and neck calibration surface 1 is used to provide a pressure application platform for the calibration of the abdomen and neck of the dummy.

[0036] The support stand 19 has at least three non-collinear legs, the legs are fixedly...

Abstract

The invention discloses a dummy child calibrating table for a car crash test. The dummy child calibrating table comprises a support table frame, a measuring mechanism and a control mechanism, wherein the measuring mechanism and the control mechanism are arranged on the support table frame. The dummy child calibrating table further comprises a data collection mechanism controlled by a main program and connected with the measuring mechanism. The dummy child calibrating table is based on body constitution of test dummy children, combines with relative laws and regulation standard requirements, is specifically designed according to calibrations required by the dummy children and can be calibrated on multiple portions including the necks, the lumbar vertebras and the abdomens. The calibration data can be collected in real time, the data are variable in format and easy to analyze and compare, equipment motion and data recording time are accurate, the test result is ensured to be real and reliable, and the output mode is simple and obvious. The dummy child calibrating table is convenient to operate, stable in performance and low in prices and can be used for calibrating the neck, the lumbar vertebra and the abdomen of the dummy children.

Description

technical field [0001] The invention relates to a vehicle safety performance detection device, in particular to a children's dummy calibration table for a vehicle collision test. Background technique [0002] Automobile crash test is to analyze the motion state and injury situation of the vehicle and the occupants (collision dummy) before and after the collision by reproducing the form of the traffic accident, and use this as a basis to improve the vehicle structure design, add or improve occupant protection in the vehicle It is the most basic and effective method to comprehensively evaluate the safety performance of automobiles at present. Since the automobile crash test is a non-repeatable destructive test and the test is unique, it is required that the test vehicle must accurately complete the collision according to the pre-set procedures. The test involves many measurement links, and various measuring equipment must be able to accurately record The state of motion and i...
