Description
Technical field
The present invention relates to train operating safety passive protection field, be specifically related to a kind of for the anti-tram-scrapping device in the collision impact of EMU or city railway vehicle.
Background technology
In recent years, train passive protection receives outer in the industry concern, vehicle operating safety pay attention to by increasing people.Wherein, the safety of train should be considered from two parts, that is: active defense and passive protection.Active defense comprises train network and Train Control Technology, rationally sound railway signal and the measure such as warning, railway clearance safety precaution, and object realizes train line safe in operation by management.Passive protection mainly goes to consider from train itself; its objective is and ensure when all active safety safety methods lost efficacy; vehicle passive security safety method should be passenger and provides last pipe protection, ensures the safety of the existence of driver and conductor, escape space and driver and conductor to greatest extent.
Statistical information according to world's railway major accident finds, causes collision case in the railroad accident of great personal casualty to account for 56%, and up to now, collision remains one of major accident risk that train faces.Although countries in the world have employed the advanced active defense technology such as communication and signal system, dispatcher's control to evade the generation of train collision accident, but train collision accident still cannot be avoided completely, since 1997, the serious car accident that only passenger train occurs in the world just has 36, cause 1259 people to be murdered, more than 3069, people is injured.
In order to avoid the generation of above collision case, the country such as the U.S., Europe is all studied the passive protection design of train.Wherein, the United States Federal railway cuncil (FRA) starts " bullet train system safety " project research, and crash survivability is as a part for project, and overall goal improves the crash-worthiness of passenger train installation.The project of relevant railway crash survivability has been carried out in European Countries cooperation, research project aims at the safety of vehicle, in-depth study is carried out from the structural constituent at energy absorbing, living space integraty, vehicle collision interface (mainly referring to hitch and anti-creeper) and derailing protection 4 aspects, wherein SNCF (SNCF) according to nineteen eighty-two ~ 1992 10 years between cause the collision case data of occupant's heavy casualties to obtain 2 conclusions, wherein one of a conclusion i.e. train " is climbed up " occupant's death in the rear-end collision of an other train and is occupied total death toll 80%; It can thus be appreciated that climb car phenomenon is a kind of more common phenomenon in train collision process, it is also simultaneously one of the problem that must consider of research passive security designer.Meanwhile, France has carried out a large amount of energy absorbing components (end underframe, anti-creep device) impact test, proposes anti-creep device, human body bears Crashworthy raiway car-body with energy absorbing design objective and the requirements such as deceleration/decel in conjunction with numerical analysis.Devise impact-resistant energy-absorbing passenger vehicle sample car on this basis, this sample car is provided with dummy, anti-creep device, and carried out online real vehicle impact test to sample car in groups, the performance of anti-creep device and frame energy absorbing structure is by full-scale test is confirmed.
The domestic research about collision is started late, along with Chinese high ferro quantity is in quick growth in recent years, the safety performance of vehicle too pay close attention to by masses.At present, domestic about train collision research mainly through simulation analysis solving collision problem, relatively lack the in-depth study to whole train crash dynamics, technology is relatively low to the transforming degree of engineering, and there is certain gap with developed country.
The research of train collision problem was formally carried out in the later stage eighties in last century.Britain is that early start carries out the country of train collision research in the world.The United States Federal railway cuncil (FRA) also starts " bullet train system safety " project research.France and Germany have made large quantity research to Structural Crashworthiness equally.
Given this present invention is proposed.
