Design of bionic energy harvesting damping seat based on power bond graph theory
In order to effectively attenuate the low-frequency vibration of construction machinery vehicles,a energy harvesting damping seat designed for heavy-duty vehicles is developed.Firstly,the"X"type shock absorbing structure is designed to imitate the multi-link series structure of kan-garoo lower bones.Secondly,the power bond graph is used to establish the damping seat model,and the numerical simulation is carried out by MATLAB/Simulink module.Finally,SolidWorks is used to build a three-dimensional model,which is imported into ADAMS for motion simulation and compared with the numerical simulation results.The simulation results show that the higher the vibration frequency,the higher the output power of the energy harvesting system.When the vibra-tion frequency is 2 Hz,the peak output power is 0.75 W,which can supply power to the sensors inside the vehicle.Therefore,the energy harvesting system of the seat can achieve damping and energy harvesting effect,which provides a new idea for the energy-regenerative performance of the damping seat.
