Hybrid III-50-RS dummy for secondary collision test of train

Abstract

The invention relates to a Hybrid III-50-RS dummy for a secondary collision test of a train. A head assembly is connected with a neck assembly through a neck rotating pin (1-6); a chest assembly is connected with a neck assembly and a chest adapter (6-1) of a lumbar vertebra assembly (6) through a spine assembly (3-3); an upper belly assembly (4) is piled on a lower belly assembly (5) and is packaged by a belly cloth bag (5-7); the lower belly assembly (5) is welded on the lumbar vertebra assembly (6) through left and right side sensor welded support assemblies; the lumbar vertebra assembly (6) is connected with the spine assembly (3-3) of the chest assembly through the chest adapter (61) and is fixed on a pelvis of a hip assembly (7) through a pelvis connecting plate; arm assemblies (8) are locked on the shoulder assemblies of the chest assembly; and leg assemblies (9) are fixed on the hip assembly (9) through thigh skeletons (9-1). The hybrid III-50-RS dummy can more truly reflect the damage of the internal parts of the train to the human body.

Description

technical field [0001] The invention relates to the field of train crash tests, in particular to a Hybrid III-50 for train secondary crash tests th -RS dummies. Background technique [0002] In the early 1980s abroad, there were literature reports related to the concept of reducing the severity of collisions and improving energy absorption. Later, research by British scholars put forward the concepts of crash-resistant car body structure design and absorbing collision energy by means of controllable large deformation. They also carried out physical collision tests, and conducted quasi-static impact tests on the end of the car body on a self-made test bench. and head-to-head crash tests of two full-size trains, among others. In the 1990s, the British Railway Management Committee established a special research institution to deal with train collision problems. Through theoretical and experimental research, British researchers have summarized the design methods and principle...

Problems solved by technology

[0003] Although there are some studies on the secondary collision injury of train occupants, there is no special dummy for the research on the secondary collision injury of trains. Instead, the Hybrid III-50, which is commonly used in the automotive industry, is used. th The dummy is used as a standard, and its abdomen is made of foamed polyurethane and PVC skin. It has no sensor for measuring abdominal invasion, and cannot reflect abdominal damage. The liver and spleen in the upper abdomen are easily damaged, so it is developed for secondary collisions of trains. dummy is necessary
