联合太平洋公司的试验表明:大量的噪声可显示出滚柱轴承的缺陷,这种缺陷能用安装在道旁的装置自动地探测。在距离Omaha以西约50英里的NorthPlatte分部,联合太平洋公司正进行着一项用音响探测有缺陷的滚柱轴承的探测机样机的控制试验。
Experiments by Union Pacific have shown that a significant amount of noise can indicate roller bearing defects that can be automatically detected by a road-mounted device. At NorthPlatte, about 50 miles west of Omaha, United Pacific is conducting control tests on a prototype of a probing machine that uses sound to detect defective roller bearings.
