摘　　要：为了验证闭环控制增压式挠性体摩擦传动机理的客观性 ,以带式输送机为例 ,阐述了其结构设计思想 ;制作了基于该理论下的实验机 ;在不同反馈系数的情况下 ,进行了极限摩擦传动牵引力的测试 ,并与理论计算数值进行了比较 .结果表明 ,当反馈系数Kf<0 51时 ,Symax随Kf和Sl 的增大按一定规律递增 ;当Kf=0 6和 0 8时 ,传动装置不打滑 .其结果验证了增压摩擦传动的有效性 ,表明理论研究所提出的极限牵引力数学模型是正确的 .To prove the objectivity of the mechanism of close loop controlled booster frictional drive, exemplifying belt transportation machine, conceive of its construction design is illustrated and then fabricating a experiment based on this theory. Under the different feedback coefficient, test of limit frictional drive has been made, and compared with theoretical calculation values. The results show that: when feedback coefficient K f<0 51, S ymax will increase progressing according to fixed law with K f and S l; when K f=0 6 and 0 8, the transmission device will not slippage. The results prove the validity of booster frictional transportation, and show that the mathematical model of limit drawing force, mentioned in theoretical study is correct. It is also analyzed that difference between experimental test and theoretical calculation.
