摘  要：導(dǎo)電滑環(huán)是實(shí)現(xiàn)兩個(gè)相對(duì)旋轉(zhuǎn)機(jī)構(gòu)之間電流、信號(hào)傳輸?shù)难b置。本實(shí)驗(yàn)探究刷絲結(jié)構(gòu)與轉(zhuǎn)速對(duì)配對(duì)副材料的摩擦性能影響。結(jié)果表明：常溫常壓下，配對(duì)副的接觸面積越大，摩擦系數(shù)越大，接觸電阻越小;反之，摩擦系數(shù)越小，接觸電阻越大;單絲結(jié)構(gòu)配對(duì)副材料的摩擦系數(shù)最小且穩(wěn)定。

關(guān)鍵詞：導(dǎo)電滑環(huán);刷絲結(jié)構(gòu);轉(zhuǎn)速;摩擦系數(shù);接觸電阻

Abstract： The conductive slip ring is a device that realizes the transmission of current and signal between two relative rotating mechanisms. In this experiment， the effects of brush wire structure and rotational speed on the friction properties of pair materials were investigated. The results show that under normal temperature and pressure， the larger the contact area of the pair is， the larger the friction coefficient is and the smaller the contact resistance is; on the contrary， the smaller the friction coefficient is， the greater the contact resistance is; in this case， the friction coefficient of monofilament structure is the smallest and stable.

Keywords： conductive slip ring; brush wire structure; rotational speed; friction coefficient; contact resistance
