Problems solved by technology

According to market demand, the research and development of standard EMUs with a speed of 350 kilometers per hour (that is, 16 formations) has been put on the agenda, and the crashworthiness of the car body is in accordance with the EN15227 standard, because there is currently no crashworthiness program for long-set EMUs at home and abroad. It can be used for reference, so it is necessary to develop a new EMU car body crashworthiness scheme

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0024] The design method of the crashworthiness performance of the 350-kilometer-per-hour long-braided EMU car body of the present invention, under the premise of meeting the EN15227 standard, designs the energy dissipation distribution scheme for each collision interface of the whole train, and sets a platform for each collision interface energy-absorbing element The force, travel, and design of the energy-absorbing elements enable the step-by-step energy dissipation process in a controlled manner.

[0025] According to the GMRT2100 standard, the maximum platform force of each collision interface should not exceed 3000KN, so the design parameters of the platform force and stroke of each collision interface energy-absorbing element are as follows:

[0026] The platform force of the crush tube of the head car coupler 1 is 1800kN, and the stroke...

Abstract

The invention provides a method for designing the train body anti-collision performance of a long-numbered motor train unit with the speed per hour of 350 kilometers and relates to the technical fieldmotor train unit train body anti-collision performance design. The method includes three parts of head vehicle energy absorption design, middle vehicle energy absorption design and energy absorptiondesign of each collision interface. According to the method, energy absorption elements are adopted to finish the energy dissipation process step by step in a controllable mode, the requirement of static strength of a train body, the available space of a head vehicle, the influence of the minimum compression amount of air dampers of middle vehicles on the energy absorption elements and the designed energy absorption amount of each the collision interface are fully considered, and the EN15227 standard requirement is met after one-dimensional simulated analysis validation. The energy absorptionamount distribution scheme of the method is firstly researched and developed for sixteen grouped long-numbered motor trains, the energy absorption amount of each the collision interface is distributedreasonably, and reference is provided for research and development of the anti-collision performance of train bodies of other long-numbered motor trains.

Description

technical field [0001] The invention relates to the technical field of crashworthy performance design of an EMU car body, in particular to a design method for the crashworthy performance of a 350-kilometer-per-hour long-braided EMU car body. Background technique [0002] With the successful research and development, trial production, test, operation assessment and other stages of testing of the 350 km / h short (8-car formation) standard EMU, mass production has now begun. According to market demand, the research and development of standard EMUs with a speed of 350 kilometers per hour (that is, 16 formations) has been put on the agenda, and the crashworthiness of the car body is in accordance with the EN15227 standard, because there is currently no crashworthiness scheme for long-set EMUs at home and abroad. It can be used for reference, so it is necessary to develop a new EMU car body crashworthiness scheme. [0003] The train changes from short to long, curb weight changes ...
