Equal Strength Optimal Design of Planetary Gear Transmission
Journal of Physics: Conference Series, 2023 Abstract In the design of planetary gear transmission, some gears are damaged during early use because of low strength, yet some are big structure sizes with high strength. In the paper, gears’ equal strength and minimum volume of the gearbox is regarded as optimization objective, and the exterior point penalty function method is used to
