Internally developed, specifically for bellows life cycle prediction, our bellows design program uses standard stress analysis algorithms combined with empirical test data. This analysis tool allows for varying design details such as diaphragm plate shape and thickness, material selection and diameter and length. Operating conditions are also factored in including cycle profile, pressures and temperatures. This tool allows for design optimization while ensuring that the cycle life will be exceeded.

3D solid modeling provides realistic images of the final assembly during design. This capability assists in determining the final interface configuration as well as providing detailed an accurate weight and CG analysis. Models are provided to customers for use in their system level models to ensure proper fit.

FEA is used to model bellows and complex assemblies. These models consider environmental effects such as thermal, pressure, vibration, and shock loads. Careful analysis of the predicted stresses allows for optimizing designs to provide the lightest, strongest, most cost-effective solution.

Prototypes are tested in the engineering test laboratory. The lab includes facilities for bellows cycle testing under actual operating conditions. Test chambers allows for testing at temperature and pressure extremes. The lab also includes a hydraulic test facility.

Metallurgical knowledge and experience is incorporated into every bellows design, as well as the design of tools and processes used to manufacture bellows. The Metallurgy Engineering Department provides material analysis for material development, design validation, quality control and production control verification. It is equipped with the latest materials tests and inspection equipment to provide material properties and hardness, metallography, macro etch, high-magnification imaging, bulk alloy chemistry.
