Latest Patents

One of his latest patents is the "Quasi-static calculation method for lateral unbalanced force of transmission lines." This invention quantifies the significant unbalanced force caused by a failed tower to an adjacent tower. It allows for a quantitative evaluation of the cascading failure risk of transmission lines. The method does not require extensive iterations and can reveal the influence of various factors on unbalanced force. Additionally, it quantifies the effect of large deformation on wind load and corrects the wind load calculation error caused by vertical height differences. This innovation optimizes existing wind load calculation methods for transmission lines.

Another significant patent is the "Axial displacement amplified eddy current damper." This device converts the axial movement of a slide bar into the rotation of copper sheets, generating eddy current for energy consumption. The design allows for high energy consumption efficiency, as a short displacement of the slide bar can cause a large angle rotation of the copper sheets. The damping parameters can be adjusted by modifying the magnetic field strength of permanent magnets, ensuring a long-term and stable vibration reduction effect without the need for external energy.
