摘要

通过对牵引特性曲线测试的加速度法和电功率法的对比分析，提出一种将加速度法和电功率法相结合用来测量城市轨道交通车辆牵引特性曲线的新方法，即在恒转矩区采用加速度法，在恒功率区和自然特性区采用改进的电功率法。试验表明，该方法充分结合加速度法和电功率法的优点，能有效提升测试的精度。

Abstract

Based on the comparative analysis of acceleration method and electric power method in traction characteristic curve test, a new method combining acceleration method and electric power method was proposed to measure traction characteristic curve of urban rail transit vehicles, that is, acceleration method was adopted in constant torque area, and improved electric power method was adopted in constant power area and natural characteristic area. The test showed this method combine the advantages of acceleration method and electric power method, and could effectively improve the test accuracy.
