【摘要】：為研究碳纖維織物增強(qiáng)樹脂基摩擦材料在摩擦過程中的溫度分布規(guī)律,以評(píng)價(jià)此類材料的耐熱性能。采用有限元分析與單胞模型相結(jié)合的方法,分別建立淺交彎聯(lián)、淺交直聯(lián)和深交聯(lián)3種結(jié)構(gòu)的碳纖維織物增強(qiáng)樹脂基摩擦材料有限元模型,模擬特定工況下的摩擦副熱傳導(dǎo)過程,分析織物結(jié)構(gòu)和編織密度對(duì)溫度分布的影響規(guī)律。結(jié)果表明:在摩擦副接合過程中,摩擦溫度先升高后降低,摩擦結(jié)束時(shí)刻的最高溫度出現(xiàn)在對(duì)偶片中心對(duì)稱面處;相同編織密度時(shí),淺交彎聯(lián)織物結(jié)構(gòu)導(dǎo)熱性能最優(yōu),其摩擦溫度峰值最低(僅為168.5℃,其他兩種結(jié)構(gòu)摩擦材料的摩擦峰值溫度分別為178.0℃和172.1℃);隨緯紗編織密度的增加,淺交彎聯(lián)碳纖維織物增強(qiáng)樹脂基摩擦材料中碳纖維體積分?jǐn)?shù)增大,導(dǎo)熱性能變優(yōu),摩擦峰值溫度降低。
[Abstract]:In order to study the temperature distribution of carbon fiber reinforced resin based friction materials during friction, the heat resistance of such materials was evaluated. The finite element models of carbon fiber reinforced resin-based friction materials with three kinds of structures, namely, shallow-bend, shallow-cross-straight and deep-crosslinked, were established by combining the finite element analysis and the unit cell model, respectively. The heat conduction process of friction pairs under specific working conditions was simulated and the influence of fabric structure and braiding density on temperature distribution was analyzed. The results show that the friction temperature rises first and then decreases, the highest temperature at the end of friction occurs at the center symmetric plane of the pair, and the thermal conductivity of the fabric structure is optimal when the braiding density is the same. Its friction temperature peak value is the lowest (only 168.5 鈩，
