Description

technical field [0001] The invention relates to a simulation system for comfort research of a high-speed vehicle, in particular to a simulation experiment system for a generalized comfort degree of a passenger compartment of a high-speed vehicle. Background technique [0002] In recent years, with the rapid development of high-speed rail, an important topic following the research on high-speed train operating speed, service reliability, and operational safety is the comfort of passengers during high-speed train operation. In the research on vehicle passenger compartment comfort, low-speed vehicles mainly consider the impact of vibration on passenger comfort. However, in high-speed vehicles, in addition to the aggravation of vehicle vibration, there is a strong airflow in the high-speed environment, and the passenger compartment space forms a transient pressure. Waves, under the action of strong vibration and strong airflow, will inevitably induce noise with complex chara...

Problems solved by technology

However, in the conventional simulation system, the simulation of pressure is not involved, especially the simulation of instantaneous fluctuation of pressure

Considering the special environment of high-speed trains, the generation of pressure fluctuations in the train is a unique product of the rolling stock operating at high speed. The air effect is very small under the action of low speed. They all involve instantaneous pressure fluctuations, so the existing technology is difficult to meet the simulation requirements of train temperature, humidity and pressure fluctuations
