PREMΛP: Exploring the Design and Materials Space for Gears

Design of a gear that meets specified requirements is a challenging task. Competition from other power transmission components as well as increasing demands from industry such as increased power density, low noise etc., are forcing gear designers to design gears using novel methods (which are beyond the traditional standards based design methods). We, at Tata Consultancy Services, are developing a Platform for Realization of Engineered Materials and Products (PREMΛP), which helps a designer exploit the synergy between component design, material design and manufacturing. One of the key features of PREMΛP is its decision support capability, which we are demonstrating using design of spur gear as an example. The compromise Decision Support Problem (cDSP) construct is used to formulate the problem and the software DSIDES to solve it. Results obtained are well in agreement with existing knowledge of gear design. Ternary contour plots are created which show the compromise between various goals and associated standard deviation.
