【摘要】 通过对５００ｋＮ实验液压装置传递纵向力的实验研究，确定了液压传力系统油液压缩模量、系统空气含量、活塞摩阻力及系统节流等主要参数的测试方法，给出了各参数的大小或变化规律，为该类系统在实际桥梁上的应用提供了技术依据。更多还原

【Abstract】 Based on experimental researeh on a 500kN hydaulic braking force transmission device(HTD),several measurement mehtods for major parameters such as compression module of hydaulic oil,air content; piston friction and restriction behavior of the throttle are establislied.The magnitude or the regularity of the above mentioned parameters given in the paper provides technical basis for HTD’s application in a practical railway bridge.更多还原
