Problems solved by technology

[0003] Although there are some studies on secondary collision injuries of train occupants, there is currently no dummy specifically for the study of train secondary collision injuries. Instead, the Hybrid III-50th dummy commonly used in the automotive industry is now used as the standard. The abdomen It 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 necessary to develop a dummy for secondary train collisions.

Abstract

The present invention relates to a Hybrid III-50th-RS dummy for train secondary impact test, wherein the head assembly is connected with the neck assembly through the neck rotation pin (1-6); the chest assembly is connected with the spine assembly ( 3-3) Connect with the chest adapter (6-1) of the neck assembly and lumbar spine assembly (6); the upper abdomen assembly (4) is stacked on the lower abdomen assembly (5) and used with the abdominal cloth bag (5-7) Encapsulation; the lower abdomen assembly (5) is welded on the lumbar assembly (6) through the left and right sensors; the lumbar assembly (6) is connected to the spine assembly (3) of the chest assembly through the chest adapter (6-1) ‑3), fixed on the pelvis of the hip assembly (7) through the pelvis connecting plate; the arm assembly (8) is locked on the shoulder assembly of the chest assembly; the leg assembly (9) passes through the thigh frame (9) ‑1) Attach to the hip assembly (9). The invention can more truly reflect the damage to the human body caused by the internal parts of the train.

Description

technical field [0001] The invention relates to the field of train collision test, in particular to a Hybrid III-50th-RS dummy for a train secondary collision test. Background technique [0002] In the early 1980s, there were literature reports related to the concept of alleviating collision severity and improving energy absorption. Later, the research of British scholars put forward the concept of crash-resistant car body structure design and the absorption of collision energy in a controllable large deformation way, and also carried out physical crash tests, and conducted quasi-static impact tests on the end of the car body on a self-made test bench and frontal head-to-head crash tests of two full-size trains, etc. In the 1990s, the British Rail Regulatory Commission set up a special research body to deal with train collision problems. Through theoretical and experimental research, British researchers summed up the design method and principle of crashworthiness vehicle s...
