Development of a High Performance, Heavy Duty Piston Seal

摘要

Today's hydraulic system applications are becoming more performance demanding, taxing cylinder operation. To keep pace with industry's demands, the requirement for high performance seals is a necessity. To achieve the required performance, piston seal development starts at the concept stage with a design to match the application. The next stage utilizes finite element analysis to ensure proper design from a theoretical standpoint. The final stage is the physical testing of the seal to confirm proper performance. This paper will discuss, in detail, four main areas: 1. Drawbacks of current & older piston seal designs 2. Development of a new piston seal using finite element analysis 3. Physical testing of the new piston seal 4. New piston seal's ability to overcome the deficiencies confronted by current & older piston seal designs.
