Analysis and optimization of nitrile butadiene rubber sealing mechanism of ball valve

Abstract:An approach for analyzing and optimizing sealing mechanism of ball valve made of nitrile butadiene mbber(NBR) with finite element method was presented. The Mooney-Rivlin hyperelastic material model was chosen to characterize NBR sealing, as it has been recommended in the similar applications. That is, NBR sealing was modeled as incompressible hyperelasticity, as well as the assumption of isotropic flow. The results illustrate the structural pressure and contact pressure on the contact surface, which shows that the NBR sealing mechanism is very suitable for sealing after dimension optimization. 作者: Author: Xue-Guan SONG  Lin WANG  Young-Chul PARK 作者單位: Department of Mechanical Engineering,Dong-A University,Busan 604-714,Korea 期 刊: 中國(guó)有色金屬學(xué)報(bào)(英文版)   ISTICEISCI Journal: TRANSACTIONS OF NONFERROUS METALS SOCIETY OF CHINA 年,卷(期): 2009, 19(z1) 分類(lèi)號(hào): Keywords: nitrile butadiene rubber(NBR)    elastomeric seal    finite element method    contact pressure    機(jī)標(biāo)分類(lèi)號(hào): V22 TQ3 機(jī)標(biāo)關(guān)鍵詞: butadiene rubber    incompressible hyperelasticity    hyperelastic material    finite element method    contact pressure    contact surface    NBR    analyzing    approach    results    model    made 基金項(xiàng)目: Technical Center for High-Performance Valves from the Regional Innovation Center (RIC) Program of the Ministry of Knowledge Economy (MKE), Korea
