Current development of the coatings for high speed rolling stock;

Development of a new type brake disc for rolling stock;

The causes to derailment,overturning accidents of rolling stock are analyzed.

With the increasing in speed and load of railway car, the dynamic performance of railway car and its components are demanded higher.

In order to develop the inverters for railway cars which have high performance and can meet requirements of the 21st century,the latest power appliance in the world——intellectual module with high voltage endurance(HVIPM)——is applied by the Japan Railway,thus,the point type inverter is changed into the two point type,the electric circ.

The design of rubber parts in railway vehicles with finite-element analysis;

Self-powered active lateral suspension system of railway vehicle;

Dynamic characteristic of new hydro-pneumatic buffer for railway vehicle;

Application of sound intensity theory in noise measurement and analysis of high-speed railway vehicles;

Reliability and safety technologies for the structure strength of railway vehicles in the future;

In the paper,through measurements of interior noise of existing railway vehicles in china, studies propagation routes and distributing characteristics,puts forward to the distributing rules of interior noise in different statuses and speeds,gets the main frequency band ,it benefits to noise abatement and reduction design of existing and high-speed railway vehicles.

Meanwhile the analysis model was assembled to analyse vehicle dynamics with other parts of rail vehicle system in ADAMS/Rail12.

By analyzing collision accidents on the European railways, the author points out that it is necessary to improve crashworthiness further on rail vehicles.

The major requirements of the body of rail vehicles were corrosion resistance,light weight,high rigidity and low costs.
