We lead in the analysis of rotating bodies using specialized software for fluid film bearings, magnetic bearings, and coupled analysis with bearings, as well as optimization CAE analysis techniques.
MADYN2000 is a finite element software developed by experts in bearings for coupled analysis of rotating bodies and bearings. It allows for smooth performance analysis of rotating bodies, optimization analysis of various parameters of bearings, and coupled analysis with active magnetic bearings and their PID control systems. The calculation of support stiffness for rolling bearings utilizes software and libraries from Swiss company MESYS AG. 【Features】 ⇒ User-friendly with a sophisticated Windows interface. ⇒ Easy model creation with copy and paste functionality for input data. ⇒ Smooth unit selection and conversion with unit assistance features. ⇒ Developed on the MATLAB platform, facilitating collaboration with experimental data processing. Executable analysis functions (rotating bodies: lateral and torsional vibrations) - Support load analysis - Complex eigenvalue analysis at rated speed - Frequency response and unbalance analysis - Transient response and speed-up analysis - Parameter variable analysis → Campbell diagram → Critical speed map → Sensitivity analysis of support stiffness and dampers → Sensitivity analysis of coupling stiffness

basic information
The rotor is fundamentally a beam structure. MADYN2000 uses fourth-order Hermite polynomials for finite elements to model the elasticity and inertial forces of the rotor, incorporating Timoshenko beam theory and gyroscopic effects. A characteristic of systems that combine rotors, gears, and bearings is that all shafts are parallel. MADYN2000 has been designed to make handling such systems easier compared to a general finite element model where beam elements can have arbitrary orientations. MADYN2000 can handle very complex rotor structures that include various types of bearings, fluid-rotor interactions based on coefficients, parts elastically supported on shafts, and a mix of bearings with different dynamic characteristics. The housing and base that can be treated as finite element models can be considered as bearing support components based on displacement and force transfer functions. MADYN2000 can analyze axial, torsional, and bending vibrations. It can also take into account the coupling of vibrations generally caused by gears.
