The new generation of condition monitoring and diagnostics systems differs by the detailed solution of diagnostic problems that allows making a step from machine vibration state monitoring to the monitoring of the machine technical condition. Most rotating machine defects can be detected by such a system much before dangerous situations occur. It allows the efficient use of stationary on-line c...

Comparing with fixed shaft gearbox, vibration properties of planetary gearbox are much more complicated. In a planetary gearbox, there are multiple vibration sources as several pairs of sun-planet gears and several pairs of ringplanet gears mesh simultaneously. In addition, the signal transmission path changes due to the rotation of the carrier. To facilitate fault detection of a planetary gear...

Genetic algorithms (GAs) have proven to be a valuable method for solving a variety of hard combinatorial optimization problems. In this paper, we develop a pair of GAs to solve a layout problem in the fashion industry. Over the past years, a number of integer programming (IP) models have been constructed that are capable of solving small, real life layout cases in an acceptable amount of time. ...

In practice, the cost of a gearbox plays very important role in trade. Therefore, reducing gearboxes is an task not only when manufacturing but also designing them. order to reduce gearbox, there are many solutions which determining optimal partial gear ratios effective measure. This because it size, mass depends greatly on ratios. work presents method for calculating function two-stage helical...

One of the well-known evolutionary algorithms inspired by biological evolution is genetic algorithm (GA) that is employed as a robust and global optimization tool to search for the best or near-optimal solution with the search space. In this paper, this algorithm is used to solve unequalsized machines (or intra-cell) layout problems considering pick-up and drop-off (input/output) points. Such p...
