【摘要】 根据钻井工艺对钻机气动刹车橡胶活塞膜性能的要求 ,应用有限元分析软件ANSYS分别对其材料选择、形状设计、结构设计进行了分析研究 ,确定了气动刹车橡胶活塞膜的形状、结构和材料 ,并给出了新设计的橡胶活塞膜的三维实体模型。相应的对比试验结果表明 ,新设计的橡胶活塞膜使用寿命大大提高 ,试件的各项性能指标与ANSYS分析结果较为一致更多还原

【Abstract】 According to the requirement of performance of the rubber piston membrane of pneumatic brakes in drilling well technology, with the finite element analysis(FEM) software ANSYS to study material selection, the profile and structure design, respectively, 3 D model of newly designed rubber piston membrane , such aspects as form, structure, and material of the rubber piston membrane of pneumatics brakes were definite, and 3 D model of newly designed rubber piston membrane was given . The corresponding contrastive experiment indicated that the service life of newly designed rubber piston membrane was improved greatly and each term of the performance of test piece in concert with the result drawn by FEM software.更多还原
