GM机车集团(GMLG)的三轴HTCR径向式转向架最近在位于科罗拉多州普韦布洛运输试验中心以及在伯灵顿北方铁路、圣菲铁路和联合太平洋铁路的有关区段进行了为期13个月的试验。进行这些试验的目的是: ——确定不同设计的径向式转向架的粘着特性、曲线通过性能以及行驶平顺性; ——确定径向式转向架零部件承受的负荷水平; ——对选作批量生产的三轴径向式转向架(HTCR)进行系统综合试验。现场试验使用了装有测量装置的轮对、测力计、测定加速度用的加速计以及用来确定与径向式转向架设计有关的各种力和运动的位移
GMLG’s three-axis HTCR radial bogies were recently run at the Pueblo Transit Test Center in Colorado and in the relevant sections of the Northern, Burlington, Santa Fe and Union Pacific railroads in Burlington Month’s test. The purpose of these tests is to: - determine the sticking characteristics, curve passing performance and ride comfort of the different designs of radial bogies; - determine the level of load to which the radial bogie parts are subjected; Mass production of three-axis radial bogie (HTCR) for system integration test. Field tests used a wheelset equipped with a measuring device, a dynamometer, an accelerometer for measuring acceleration, and various forces and movements used to determine the design of the radial bogie
