• Zero-Max Composite Disc Coupling Provides Increased Torque Requirements to M1A2 Abrams Main Battle Tank New Air Filtration System
  a rugged composite material. These two features give it the high misalignment capacity of many elastomeric couplings but with higher torsional stiffness. Compared to steel disc couplings, the CD(R) Coupling offers superior damping and isolation of shock and vibrating loads, a very important...
• Get Reliable Results From Rubber Test Data
  and over time. However, an FEA model is only as good as the material parameters it's based on. Getting good material data can be challenging enough for linear-design purposes, but elastomeric materials complicate matters with nonlinear and viscoelastic behavior. Nonlinearity arises from rotations...
• Top Trends Impacting Design Engineers, part 2
  formulations - for instance, perfluorinated elastomers that offer broad chemical and temperature resistance - meet the most demanding static, dynamic, and environmental applications. And tools such as FEA software specifically tailored for elastomeric analysis let engineers design and predict a seal's...

  . Perhaps more important than these materials toxicology is their potential to elicit serious immunologic responses, even at minute dosages. Fluorocarbon film protects against extractables Fluorocarbon films provide a barrier to protect the drug product against extractables from the elastomeric material...

  and cool-down. The gasket material was characterized and the shape of the unconstrained portion of the gasket was modeled using finite element analysis (FEA) techniques. The shape is bulbous. During expansion, the gasket extrudes radially, and the unconstrained portion expands axially. During contraction...

  Analyzer. CEM. Matthews, NC. Designed for ultratrace contamination detection, the CleanSTAR microwave analyzer system automatically prepares samples of ultrapure chemicals, water, and other raw materials for parts-per-billion and parts-per-trillion analysis. The instrument reduces the time needed...
• Quantifying Comfort
  with the correct geometry. Samples come next, and, finally, the seat must be readied for testing. Numerical simulation using finite-element analysis (FEA) is a valuable tool for shortening this complex design process. The process of modeling seats in a virtual environment links CAD with material databases...

  to be modified. Analysis and Metrology: Partial-pressure analyzers can not only be used to identify and monitor residual gases during a contamination event; they also are effective tools for full-time process monitoring. Ultrapure Materials-Fluids: A well-designed recycling system that ensures removal...

  , during both analysis and sterilization processes. Furthermore, the move towards increased analytic power with less sample volume has driven down the size of system components. Seals and gaskets play a significant role in determining the reliability of a fluid-control system. These trends have...

  elastomeric components such as vial stoppers and syringe plungers. A risk analysis can help identify a potential adverse effect to the product caused by system components, which helps the biopharmaceutical company to prevent or eliminate the potential risk. Risk control and mitigation are pertinent...
