RAIL VEHICLE, RAIL VEHICLE COLLISION AVOIDANCE SYSTEM AND RAIL VEHICLE COLLISION AVOIDANCE METHOD

摘要

A rail vehicle, comprising several vehicle body main bodies (1), vehicle body front-end structures (2) located in front of the vehicle body main bodies (1), anti-creepers (3) and coupler and draft gear systems (4), wherein cubicle areas at two ends of each vehicle body main body (1) are provided with vehicle body passenger compartment high-order deformation and energy absorption areas (D1, D2, D3), the longitudinal rigidity of which is less than that of the vehicle body main body (1); each of the vehicle body front-end structures (2), the longitudinal rigidity of which is less than that of the vehicle body passenger compartment high-order deformation and energy absorption areas (D1, D2, D3), is further arranged at the head of each vehicle; the anti-creepers (3) are distributed on two sides of the front end of each of the vehicle body front-end structures (2); the coupler and draft gear systems (4) are arranged in the middle of two ends of each vehicle; each of the vehicle body front-end structures (2) comprises collision avoidance walls (21), columns A (22) and columns B (23); energy absorption areas at the head of the vehicle are sequentially, from front to back, a coupler and draft gear system energy absorption area (A), an anti-creeper energy absorption area (B), a vehicle head first-stage deformation and energy absorption area (C1), a vehicle head second-stage deformation and energy absorption area (C2), and a vehicle body passenger compartment high-order deformation and energy absorption area (D1) of the vehicle body main body (1); energy absorption elements of the coupler and draft gear system energy absorption area (A) are the coupler and draft gear systems (4), and energy absorption elements of the anti-creeper energy absorption area (B) are the anti-creepers (3) provided with guide mechanisms (31); and the coupler and draft gear systems (4), the anti-creepers (3), the vehicle head first-stage deformation and energy absorption area (C1), the vehicle head second-stage deformation and energy absorption area (C2) and the vehicle body passenger compartment high-order deformation and energy absorption areas (D1, D2, D3) are distributed in series. A rail vehicle collision avoidance system and a method for vehicle collision avoidance are also provided.
