MPT Inc. – Microwave Products and Technology


Linear stress analysis, fatigue analysis, motion, and vibration analysis allows us to predict mechanical reliability of our products. 


Mechanical Reliability

Mechanical reliability is important in high reliability systems such as airborne, space, and military systems. Our advanced design flow based upon Solid Works Simulation suit allows our designers and engineers to quickly and efficiently perform validation, quality, performance, and safety analysis—all within the design environment.

Linear Stress Analysis calculates the stresses and deformations of product given the assumptions of the part or assembly under load deforms with small rotations and displacements, the product loading is static (ignores inertia) and constant over time, the product and materials have a constant stress strain relationship (Hooke’s law). Our linear stress analysis is based on Finite Element Method (FEM), which creates discrete elements in a mesh and solves for the response of parts and assemblies due to the effects of forces, acceleration, temperature, and contact between materials.

Fatigue analysis allows for the prediction of component fatigue failures. It is important to perform this analysis during the design phase to avoid surprises in product performance after it is too late to modify the design. This allows the designer to adjust the design or change materials and prevent failures which reduces costs and maximize product life. With the MPT design flow our engineers can design for strength or design for product life, or more likely, achieve a balance between the two.

It is important to uncover potential issues early in the design cycle and to make adjustments to the product during the design phase. This is true for vibration analysis. Proper analysis can identify trouble spots that could result in problems such as resonance, fatigue, and assembly difficulties. Detailed vibration analysis is important using frequency and dynamic analysis to ensure the final result performs safely and correctly. This is important since vibrations in a product may reduce performance, shorten product life, or even cause a catastrophic failure.
