Analysis Of Train Rolling Noise Simulation

It is a problem how to reduce the rolling noise, so many countries put the noise control research on the important position while they develop high-speed railway.Many researches show that noise along high-speed train increase apparently with the velocity increase, but the noise level will be under the present level if reasonable method is taken, such as changing the structural parameters of wheel and rail, damping optimisation, and auxiliary methods.Simulation need less manpower and material resources than experiment, and it is more convenient to analysing the effect of each parameter to rolling noise. TWINS software is the best development and the most extensive using of rolling noise analytic software, and many European country get some achievements using the software which have important effect to noise control. I translate the software to PC, and implement it in the article. An example with 160 km/h velocity is illustrated, and the analytic results show that the software can get the reliable results.
