为提高金属带摩擦传动的效率，改善搭载无级变速器的车辆的燃油经济性，研究金属带的滑移特性。搭建金属带滑移特性试验台架，通过台架试验，研究不同速比、不同夹紧力与不同主动轮转速三种工况下滑移率与摩擦因数关系的滑移特性，试验结果表明在滑移率的前段区间，摩擦因数随滑移率增加而快速增加，在滑移率的后段区间，摩擦因数保持稳定并有减小的趋势；速比对滑移特性影响明显，同一滑移率，速比越小，摩擦因数越大；夹紧力与主动轮转速对滑移特性的影响可以忽略。根据滑移特性的试验结果，提出目标滑移区域的定义——滑移效率限制区域(Slip efficiency limit region, SELR)与滑移磨损限制区域(Slip abrasion limit region, SALR)。为高效率的夹紧力控制算法的开发提供依据，为提高金属带的传动效率找到了一种新方法。

In order to increase metal belt transmission efficiency and improve fuel economy of vehicles with continuous variable transmissions, slip characters are researched. A test bench for metal belt slip characters is created and through test bench experiment, the relationship between slip rate and friction coefficient under conditions of different ratio, different clamp force, and different primary speed is researched. The results are as follows. In the forehead part of slip rate region, friction coefficient increases sharply with increase of slip rate. In the back part of slip rate region, friction coefficient changes little and has decreasing trends; Ratio impacts the slip characters significantly, when ratio is smaller, friction coefficient becomes larger; Impacts from clamp force and primary speed can be ignored. Based on experimental results of slip characters, the definition of object slip region is presented as slip efficiency limit region and slip abrasion limit region. The basis for developing high efficient clamp force control algorithm is provided and a new way to improve transmission efficient of metal V-belt is found out.
