ZaKo3D and μOpt


The three-dimensional general FE-based tooth contact analysis ZaKo3D provides the simulation and evaluation of the operational behavior for various gear types. Based on a three-dimensional representation of the tooth or tooth gap geometry (e.g. from a manufacturing simulation or gear measurement) the influence of micro geometry modifications as well as manufacturing, assembly or load induced deviations on the operational behavior can be analyzed. The scope of the software includes cylindrical gears, beveloid gears, bevel gears, face gears and worm gears.
Based on the integrated sensitivity analysis the influence of geometrical as well as mounting parameters on the operational behavior can be evaluated. The results of the sensitivity analysis can be visualized by means of a stamp diagram or can be used as input data for the program µOpt. The program µOpt offers a statistical evaluation of the sensitivity analysis in regards to a objective function. The design targets for gear design often lead to a design conflict. Thus, a weighted objective function is needed in order to weight the different design targets (e.g. durability, manufacturability, NVH and efficiency) based on the product requirements. Next, the different design variants will be evaluation in regards to tolerance fields. Based on the quality of the operational behavior and the stability of the operational behavior within the tolerance field, an optimal gear geometry will be assessed. This variant promises a function oriented and robust gear geometry in regards to manufacturing and assembly induced deviations.

Using the software in a large number of public research projects, continuous development takes place and newly gained knowledge can be made available to members of the gear circle through the software. In addition, we also offer bilateral projects involving ZaKo3D and µOpt for the design and optimization of the gear geometry. Due to the continuous further development of the modular program structure, we are able to model and analyze other gear geometry, which are not part of the current version yet, internally. With the help of these simulation models, many questions, e.g. function oriented gear design, can be answered.
