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： 中國有色金屬學報（英文版） ISTICEISCI Journal： TRANSACTIONS OF NONFERROUS METALS SOCIETY OF CHINA 年，卷(期)： 2009, 19(z1) 分類號： Keywords： nitrile butadiene rubber(NBR) elastomeric seal finite element method contact pressure 機標分類號： V22 TQ3 機標關鍵詞： butadiene rubber incompressible hyperelasticity hyperelastic material finite element method contact pressure contact surface NBR analyzing approach results model made 基金項目： Technical Center for High-Performance Valves from the Regional Innovation Center (RIC) Program of the Ministry of Knowledge Economy (MKE), Korea【Analysis and optimization of nitrile】相關文章：
