Description
Technical field
The present invention relates to a kind of drop calibration test for manikin head, particularly relate to a kind of for dummy
The elevation carrection accessory of head drop calibration test.
Background technology
Dummy is the important of data acquisition in vehicle impact testing (such as complete automobile collision test, slide unit test etc.)
Equipment.Many eurypalynous sensors such as acceleration and displacement it are disposed with inside dummy.During impact test,
The state of dummy directly affects the accuracy of data acquisition.So, need to demarcate once after multiple impacts test
Dummy.Head drop calibration test is the one in the numerous rating test of dummy, and purpose mainly checks head
Skin hardness.
Manikin head's drop calibration test is that manikin head's distance is fallen plane specified altitude assignment, records headform
The each side test data of plane is fallen, to check skin of head hardness described in portion's shock.Manikin head demarcates
Manikin head is highly had strict requirements, the range deviation of head perigee distance work top and nose
Can the distance to head minimum point directly affect head and demarcate and pass through.At present, it is to be surveyed by ruler or tape measure
Measure above-mentioned distance.
Existing ruler and the tape measure error of indication ± 1mm, and there is the collimation error when measuring, so measuring
Total error >=± 1mm.Height tolerance ± the 1mm demarcated due to head, so existing means are surveyed
Amount exists measures inaccurate problem.Additionally, during actual measurement, after adjusting manikin head
The length of end hanging steel rope adjusts the nose distance to demarcation table top, and now head can be along with steel wire rope
Length rotates before and after changing and occurring.After head rotates, along with the minimum point of the rotatable head of head is sent out
Give birth to variation, the most again change portion minimum point, measured the head minimum point distance to work top, adjust
Head minimum point is to the distance of demarcation table top, then measures the nose distance to staking-out work table top.Generally require
Substantial amounts of repeatedly regulate, requirement could be met.Measure hence with existing means and there is also work efficiency
Low problem.
Summary of the invention
It is an object of the present invention to provide a kind of elevation carrection for manikin head's drop calibration test
