Abstract:This model design of high frequency wireless induction signal transmission device is based on HFSS simulation software, in order to improve the complex manufacturing process of special wired drilling tool. By establishing induction and resonance simulation models, the simulation signal transmission characteristics are calculated and compared with the physical model to verify the influence of the parameters of the design model, such as turns, pitch, wrapping material, on the transmission characteristics. By analyzing and correcting the design scheme through the simulation results of the model, a simulation model with high consistency with multiple physical models is obtained, which can guide the design of physical models, and greatly improve the efficiency, reduce the cost and save the time of R&D. Through the model simulation method designed in this paper, the feasibility of wireless induction coupled transmission is verified. It is highly consistent with the physical model, deviation can be less than -5 dB,which provides an important basis for the physical production.
