Simplifying the complex with engineering excellence

Vancouver WA Engineering Design Services


A key distinction to reliably working products and machines is the engineering analysis that is performed. Our analysis work proves out key design parameters and allows our engineers to make intelligent, verified decisions.

Our seasoned engineers run models to analyze the stress and factor of safety of a part or assembly. Simplexity's analysis capabilities range from thermal and fluids to structural assemblies and vibration. In some products it is necessary to control critical temperatures or address thermal stress hotspots, which we address first through modeling and then prove with empirical testing. Our engineers can even save prototype/build cycles by developing kinematic and dynamic systems models of the motion of an assembly before it is built.

Occasionally, a client approaches us with a project that is almost entirely analysis; give a read to our Structural Analysis FEA case study for a terrific example of how our analysis substantiated this new innovation.
