About Dyrobes

Dyrobes is comprised of two major programs and four optional programs. All programs are integrated. The two major programs are Rotor dynamics (Rotor) and Bearing Performance (BePerf). Non-linear, time transient motion of turbocharger. Together, the two programs provide engineers with a single comprehensive tool that can analyze a rotor-bearing system without the expense of long trials. Dyrobes Rotor is capable of linear and non-linear analyses of free and forced vibrations (lateral, torsional, and axial) as well as static deflections of multi-shaft and multi-branch flexible rotor-bearing-support systems. More than ten different types of bearings, dampers and seals are built in. FEA programming allows for multi-shaft designs and modeling of bearing housings.

The wide range of bearing configurations which can be analyzed include plain cylindrical, partial arc, elliptical, lobed, multi-pocket, pressure dam, general fixed profile lobed, flexural/tilting pad with or without flexible pivots, floating ring bushings, gas lubricated bearings, and thrust bearings.

The four additional programs are Gear Loading (GearLoad); Balancing (RotBal), Advanced Thrust Bearing (ThrustBr) and Spiral Groove Face (SpiralGf).
