摘　　要：传统的检测方法存在一些不足之处,当前国内牵引电机通风试验风量测定装置是用L型毕托管根据等面积环多点测量流速的原理进行测量的,这样做不仅耗时,而且人工读数精度不高。为此本文提出了一种适合牵引电机风量检测的智能匀速管流量检测系统。本文理论分析的重点在于匀速管的检测杆截面选形及其数学模型。在综合分析国内外流量检测的现状和先进同类产品的基础上,通过对经典和现代各种方法的系统研究,分析总结各种方法的优缺点,提出新型匀速管检测系统的技术指标和总体设计方案。Traditional detection method some inadequacies current domestic traction motor ventilation test wind measuring device is L type Pitot According equal area loop multi point measurement velocity principle measurement doing so time consuming but artificial reading accuracy high. End paper proposes a suitable traction motor air volume detection Intelligent uniform tube flow detection system. Article theoretical analysis focuses uniform tube detection rod sectional election shaped Its Mathematical Model. Comprehensive analysis abroad flow measuring Status and advanced similar products basis, through classic and modern various methods system research, analysis summarize various methods advantages and disadvantages. Propose new uniform tube detection system technical indicators and design program.
