OptiMicro is fundamental when an optimization of the gears is needed; through a patented algorithm, it provides the quasi-static and dynamic behaviour of the system still ensuring high accuracy in comparison with other FEM results. For the quasi-static analyses, the algorithm is based on the load sharing analysis between the coupled teeth of the gears, that calculates the real distribution of pressure acting on the bodies in contact, the real contact ratio under load, the gears deformation and the static transmission error. Compared with FEM software, the computational time is drastically reduced up to 80%. For the dynamic analyses, OptiMicro can rely on a simple 1D model and a powerful 3D model. The first one provides important information about the nonlinear dynamic transmission error and the dynamic overload of the system layout in a few minutes.
The 3D model enables dynamics analysis for flexible bodies in a few hours, whereas other dedicated commercial softwares require months of calculations, a computational time prohibitive for any company nowadays. The innovative nonlinear time domain approach allows to quickly and accurately determine the response amplitudes of the mode shapes excited by the time-varying mesh stiffness under variable loads and speed, an invaluable input for fatigue and NVH analyses. Furthermore, thanks to the multi-objective optimization OptiMicro could be used for the design of gears made through Additive Manufacturing: indeed, it provides the best tooth profile and root fillet in terms of NVH and stress distribution for a specific application.
