气动刹车橡胶活塞膜ANSYS分析及设计

Analysis and design with ANSYS for rubber piston membrane used in pneumatic brakes.

根据钻井工艺对钻机气动刹车橡胶活塞膜性能的要求,在对橡胶活塞膜力学性能理论分析的基础上,应用有限元分析软件ANSYS对这种活塞膜的材料选择、形状尺寸、结构型式进行了分析研究,最终择优确定了新的橡胶活塞膜三维实体模型。新旧两种橡胶活塞膜试件的气压拉伸对比试验表明,新设计的橡胶活塞膜的拉伸破坏寿命大大提高,试件的各项性能指标与AN-SYS分析结果一致。

According to the requirement of drilling technology to the performance of the rubber piston membrane used in pneumatic brakes of drilling rig, based on the theoretical analysis of the mechanical properties of the rubber piston membrane, an investigation is made on the material selection, shape and structure design of this piston membrane by using the ANSYS software. And then a new 3-D entity model of the rubber piston membrane is determined. Contrast test shows that, the tension failure life of the new rubber piston membrane is improved greatly, and all the performance indexes of the test piece are identical to the results of the ANSYS analysis.
