摘要:
 根据GB/T 25117等相关标准要求,机车车辆牵引系统均需进行特性试验。标准要求在电动机冷/热状态下,在规定特性上,相应于最大转矩的转速至90%最高转速之间任何点上的典型转矩不应小于所规定值的95%。为确保机车车辆牵引系统转矩特性测量结果准确、可靠,建立了数学模型,并结合实际全面分析了不确定度产生的来源,并对转矩特性测量结果在不同的曲线段分别进行了评定,结果显示,目前采用的方法及仪器有效、可靠。该方法为机车车辆牵引系统转矩特性测量结果的可信度提供了技术依据。
Abstract:
 According to GB/T 25117 and relevant standards, the traction system of rolling stock needs to carry out characteristics test, the typical torque of all speed points under 90% maximum speed corresponding to maximum torque should not less than 95% of specified value under the conditions of hot and cold motor. To ensure the torque characteristic measurement results of locomotive traction system accurately and reliably, the measurement model was established and used to analyze uncertainty sources combining with real experiment system. Measurement results of torque characteristics in different curves were evaluated, and the results showed that the methods and instruments were effective and reliable. This method provided the technical basis for the reliability of the measurement results of rolling stock traction system torque characteristics.
