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.

Key words: pneumatic brakes, rubber piston membrane, FEM, design
