Untersuchung von Kompromisslösungen zwischen NVH und Wirkungsgrad im Kegelraddesign

Abstract Minimizing NVH and friction-induced power losses is becoming paramount in the design of geared transmissions. The aim this paper to present an automatic methodology explore Pareto-optimal designs bevel gears when minimization noise frictional essential. In first part, a semi-empirical model estimate under elasto-hydrodynamic lubrication described. has been validated against experimental data available literature previous works by authors. efficiency calculation coupled with state-of-the-art loaded tooth contact analysis (LTCA) tool obtain accurate predictions instantaneous load shared mating pairs during meshing cycle. second framework based on multi-objective optimization (MOO) presented where micro-geometry systematically designed. variables are represented few coefficients polynomial basis that embodies flank ease-off topography. To ensure manufacturability, modifications projected onto feasible set machine-tool envelopes. This step achieved through identification algorithm authors have developed work. Frictional estimated aforementioned model, whereas level measured transmission error (LTE), directly from simulation tool. maximum pressures limited material properties, thus proper nonlinear constraints prescribed. Application test case involving spiral gearset reveals allows designer solutions systematic manner.
