The design of complex mechanical components is a time-consuming process which involves
many design variables with multiple interacted objectives and constraints. Traditionally, the …

Gear pairs effectively transmit power and movement over short distances. Their design is
well-defined in the technical literature, including standards and handbooks. However, the …

When designing helical gears, the goal is to optimize gear weight, efficiency, and noise
while simultaneously achieving the required strength. In this study, the macro geometry of a …

In this study, the general form of objective function and design constraints for the
volume/weight of a gearbox has been written. The objective function and constraints can be …

Besides satisfying the essential strength requirements, gearbox design should ensure
additional desirable properties in order to be competitive. For example, a gearbox should be …

Optimization of gear trains is a complex task, due to the characteristics of mathematical
