Design and simulation of gear transmission system based on metamaterial

In this research, we integrate a three-dimensional micro-/nano-lattice structure metamaterial with conventional helical gears using composite method to reduce the vibration. A comprehensive six-degree-of-freedom nonlinear dynamics model is constructed analyze vibration characteristics of resulting mechanical gear pair. The incorporates crucial factors such as meshing damping, error excitation, bearing support stiffness, and time-varying stiffness dynamic–static method. results demonstrate good damping effect designed on pair vibrations. This research provides theoretical insights for reducing vibrations in transmission systems by metamaterial.
