The feasibility of the improvement scheme is demonstrated through the comparison and analysis of the present damping cross beams for floor in 25T type passenger cars and the improved damping cross beams in such aspects as the cost,strength,environment protection and fitting.

Development and application of bridge decreasing vibration technique;

Influence of lateral damper on locomotive riding quality;

A semi-vehicle simple model and whole-vehicle model are established by software SIMPACK, for analysis of the impact on the critical velocity of locomotive hunting movement and locomotive s major lateral dynamic performance index by the length of suspension pendulum and the lateral damper damping of motor drive unit.

In order to control the lateral vibration of car-bodies of high speed trains in tunnel sections due to atmospheric pressure fluctuation, the single-car equivalent model of installing lateral dampers between car-bodies is set up, with the consideration of actually marshalled train model, the effect of lateral dampers between car-bodies on control of car-body vibration is discussed.

This paper considers one computational method of the eigenvalues approximate value of the horizontal vibration problem of beam.

This paper considers the estimates of discrete spectrum of the horizontal vibration equation of beam.
