【摘要】 本文利用Liapunev第二方法找出了多绳摩擦提升在初始半径差任意分布情况下发生磨合运转的条件。指出只要初始半径满足关系式便会发生磨合运转。同时也证明了文献〔1〕中提出的几种情况是此结果的特例。更多还原

【Abstract】 In this paper,the condition keeping steady operstion of multi-rope friction hoisting, in case of the initial differences of rope grooves being arbitrary distribution, has been found with Liapunov second method, It is showed that so logy as the initial differences of rooeqrooves are suited for relation (?)steady operation occur certainly, In other hand, It proves that some formulas in document are speciar matter of this result.更多还原
