摘要
通过回顾近年来车辆工程的设计开发和公路行业的检测监控中,道路谱测量检测技术的理论研究和发展现状,对比分析了近年来这一领域涌现出的多种测量和检测技术的新方法。根据测试原理的不同,分为接触式测量和非接触式测量两大类来介绍。接触式道路谱测量方法的优点是测量精度高、重复性好,缺点是测量速度慢,操作复杂,测量时需要进行交通管制。非接触式测量方法优点比较明显,即测量速度快、操作简单、运行效率高,且不影响道路交通的正常运行,缺点是精度相对比较低、误差源多、价格昂贵。最后针对真实路形测量仪器的设计与开发进行了阐述,并对道路谱测量检测技术未来的发展趋势和研究前景进行了探讨。
There are many kinds of new methods of measurement and test by reviewing research progresses of road spectrum measurement in the field of automobile engineering and transportation engineering in recent years. Based on the difference of principle of measurement, two aspects are discussed. One is contact measurement method of road spectrum, in which the merit is high-precision, reproducible and the shortcoming is slow, complex operation, need traf- fic control in test. The other is non-contact measurement method of road spectrum, in which the merit is fast, simple operation, high-efficiency, no infection for the normal operation of road traffic and the shortcoming is low-precision, expensive, multi-source errors. In addition, the design and development of instrument on the true road shape measurement is described. In the end, the prospect of road spectrum measurement in the field of automobile engineering and transportation engineering is summarized.
