2.检测轨道的诊断技术 (1)2台车辆方式的新干线轨道检测装置 在新干线上检测轨道的变形是由一辆用电气·轨道综合试验车(通称修整器·黄色)组装成的轨道检测车完成,约隔10天检测一次。从前,轨道检测车是3台车方式,测定时以210km/h的速度运行,也可以用210km/h以上的高速运行,还可用营业列车的同等速度运行,并进一步以轨道检测车的轻量化为目的而使用STAR-21C(低噪声高速试验电车),铁道总研究院、日立公司、住友金属公司正在共同合作开发2台车方式的轨道检测装置。以前的轨道检测车辆是以车体作为基准面,而2台车方式
(2) Diagnostic technology of the test track (1) The test of the track on the Shinkansen track in the two vehicles is carried out by a track assembled with an integrated electric / track test car (commonly known as dresser / yellow) Test car is completed, about once every 10 days. In the past, the orbital detection car was a 3-car system, and was operated at a speed of 210 km / h during the measurement. It could also be operated at a high speed of 210 km / h or more. It could also operate at the same speed as a commercial train and further reduce the weight of the car For the purpose of using the STAR-21C (Low Noise and High Speed Tram), the General Research Institute of Railways, Hitachi and Sumitomo Metal are working together to develop a two-car track inspection system. Previous track detection vehicles are based on the body as a reference plane, and 2 trolley approach
