中文摘要：

在电梯系统的设计与制造中,电梯导靴被设计成与导轨紧密接触,并运行在其上。这种导靴与导轨间的表面接触呈现出强非线性滞回摩擦特性,并进而引起电梯轿厢的纵向和横向振动,严重影响电梯运行与乘坐舒适性。在设定的参数条件组合下,实验研究电梯导靴与导轨接触面间的滑动摩擦力及其特性,并呈现出丰富的摩擦特性,如摩擦滞回、预滑动/宏观滑动、摩擦过冲、时间滞后、速度强化或弱化特性等。另外实验中还发现不同的摩擦材料,润滑情况以及摩擦运行时间,都对摩擦特性的正确估计产生明显影响。实验结果对于靴衬材料的选取,电梯系统设计和制造,降低电梯振动水平,减小运行噪声,提高电梯乘坐舒适性,均有较为积极的意义,同时实验结果还可以为摩擦力的理论建模分析提供依据,验证模型有效性。

英文摘要：

The slide guide in an elevator moves in contact with the guide rail.This kind of surface contact exhibits a highly non-linear hysteretic friction behaviour which hampers greatly the riding quality of elevator systems.An experimental investigation into this phenomenon is presented through measuring the contact friction force between the interface of the slide guide and the rail under different combination of input parameters.The experiment shows frictional behaviours including pre-sliding/gross-sliding regimes,time lag, and velocity（weakening and strengthening） dependence.In addition,it is found that different materials in contact,lubrications and friction duration have strong impacts on evaluation of the friction characteristics.The tests give an insight into relationships between different friction behaviours and can be used to validate appropriate theoretical friction models.
