Train collision energy managing system and designing method

Abstract

The invention relates to a train collision energy managing system and a designing method. The train collision energy managing system comprises a train hook buffering device, a crushing tube, an end energy absorbing device and a train middle structure with enough rigidity, the train hook buffering device is matched with a train, and the energy is absorbed through the cooperation of the structures in the train collision process. According to the designing method, a numerical model is established according to the actual situation, simulating calculation is carried out, the calculation result is processed and analyzed, the dynamics characters of the train in the driving direction are obtained, a curve and parameter values are output, a most reasonable output curve is obtained, and the reasonable train collision energy managing system is obtained according to the output curve. The energy in the collision process is absorbed through the cooperation of the structures, the train collision energy managing system is reasonable in structure, safe and reliable, the collision dynamics characters of the train in the driving direction are accurately simulated, the design of the train collision energy managing system is guided reasonably, the design faults are effectively reduced, the designing time is saved, and the designing efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical design, in particular to a vehicle collision energy management system and a design method. Background technique [0002] With the continuous development of rail transit, more and more people pay attention to the safety of vehicle operation. Vehicle collision safety is a very important part of vehicle operation safety. [0003] Train collision safety protection technology is divided into two aspects: "active safety protection technology" and "passive safety protection technology". "Active safety protection technology" is necessary for safe operation of trains. Proper use can effectively prevent collision accidents. It mainly includes train network and train control technology, reasonable and sound railway signal and alarm system, railway boundary safety protection, etc. But "active security technology" is not 100 percent reliable. The "passive protection technology for trains" that meets the safety sta...

Problems solved by technology

However, the above-mentioned patent only improves the ability to absorb collision energy from one aspect of the energy-absorbing structure at the end of the underframe, and does not consider the management of vehicle collision energy as a whole.
