抄録

The machine tends to low energy and high efficiency. It was mainly used for oil bearing. Then, it is important that it improve the bearing performance to raise the performance of the rotational machinery. To such a problem, it was studied optimum design to improve characteristics of bearing in recently. In general, when it performed the bearing design, it was performed as multipurpose optimum design to optimize a number of objective functions at the same time. Previously, when it solve multipurpose optimum design problem, it give weight factor to each objective function, it was boil down to single objective function for the summation. However, in fact, to select weight function, it decided for try and error or judgment of value of designer. Therefore, there are problems to need the calculation number of times and take a lot of calculation time to get the optimum weight factor. In this paper, it studies about optimum design of groove geometry for thrust bearing with weight factor consideration.
