大风环境下P62K型空棚车横向振动偏移量试验研究
Research on P62K box car' s lateral vibration offset under strong winds
摘要
Abstract
Based on the method of machine vision to detect vibration offset of rolling stock, real vehicle test was done to measure lateral vibration offset of P62k box car under strong wind, and the coefficients of vibration offset were analyzed when the train stayed in the section without wind - break wall and sections with different kinds of wind -break wall under wind environment. The maximum lateral vibration offsets are 83 mm and 137 nun when the P62K box car runs in windless region and wind region, respectively. And the maximum offset is 37 mm when the car stays in wind region. The coefficient of vibration offset is maximum in the section without wind - break wall, while minimum in the section with wind - break wall of concrete sleeper type. In addition, windproof effects of wind - break walls of tendon type and concrete slab type are approach, and the effect of the earth embankment type is the worst.关键词
