高原列车车窗压差自平衡装置的研究与设计

he highland trains go back and forth between the plateau and the plains frequently. The pressure difference inside and outside the insulating glass changes continually. It will not only cause frequent reciprocating deformation, the air tightness of the compartment, but also influence working life of both windows and films attached. Aims at the structure of current vehicle window, which does not have the ideal device to effectively control the influences however, research and design of pressure difference self balancing device is the improvement, which decreases the railway operating costs moreover. The self-balancing device, real-time monitoring of the pressure change outside the train, adjusting the air pressure within the insulating glass, so as to compensate the deformation and balance the differences. The device have the characteristics of strong real-time, perfect self-adjusting and good economical efficiency, being a fundamental resolution of the pressure change on the impact of the train operating conditions, having the profound significance of the technological revolution.
