Abstract
The utility model relates to an experimental device which can carry out a detection on the antipenetration performance of a helmet. The utility model is especially suitable for the detection of the antipenetration performance of the helmet of a motorcycle occupant. The utility model is guided through a stainless steel tube and adopts a movable head type fixing support seat, which makes a landing point accurate and an experimental head type have an angle and shift regulation. The utility model can ensure the shaft line of a cone body and the tangent line of a tested point vertical when the different positions of the helmet are detected.
Description
The utility model relates to a kind of test unit that can detect helmet penetration resistance, is particularly useful for the test of the penetration resistance energy of the motorcycle passenger helmet.
The proving installation of the motorcycle passenger helmet penetration resistance that adopts is the formula penetration test platform (GB GB811-89) that falls at present, its guide rail that falls is two steel wires, steel pricker drop point deviation is bigger, because the head dummy position is fixed, when helmet different parts is tested, cone axis and measured point tangent line out of plumb influence measuring accuracy.
The purpose of this utility model is that a kind of catheter type penetration test platform will be provided, and it can make steel pricker penetrate accurate placement, test data accurately and reliably.
The purpose of this utility model is achieved in that

The utility model has the following advantages it owing to adopt stainless-steel tube guiding and portable head dummy hold-down support:
1, accurate placement, because cone is along single conduit free falling, thereby accurate placement, its error is less than ± 1.36mm.
2, test data accurately and reliably, the test head dummy can be done angular setting and left and right displacement adjustment, thereby during to the test of the different parts of the helmet, can guarantee that cone axis is vertical with the measured point tangent line.
3, two rail friction losses are little, compact conformation.
4, sound, light shows.
