摘　　要：运用功能转换概念和原理,分析了汽车起重机紧急制动过程,提出了汽车起重机在平路、上坡、下坡等3种情况下制动距离的计算方法和公式,并将计算结果列表分析。计算公式表明:决定汽车起重机制动距离的主要因素是制动初速度、路面阻力系数、道路坡度和制动力增加时间;汽车起重机总质量与制动距离无直接关系。计算方法和结果适合各种轮式起重机,为汽车起重机制动系统的设计及其制动性能的检验提供了理论基础,在道路交通安全分析方面具有实用性。It analyzes the process of urgent braking of truck crane applying concept and principle of work- energy transformarion, and gives calculating methods and formulas for the braking distance on three different roads including level and up/down slope roads and makes a list of calculating results for analysis. The calculating formulas show that braking distance depends on initial braking speed, road dragging coefficient, road slope grade, braking force increasing time; and nothing to do with total mass of crane. The calculating method and results, which could be used in various truck cranes, provide a theory basis for brake system design and brake performance check and is practical for analysis of brake performance and traffic safety of the crane on road.
