• Magnetic Field Intensity and ControlThe performance of electromagnetic shock absorbers can be altered by adjusting the size of the air gap,which affects the magnetic field intensity.Its important to ensure the control module accurately monitors and controls the magnetic field to achieve the desired damping effect.
• MaintenanceCompared to traditional friction and oleo dampers,electromagnetic dampers have advantages in maintenance,environmental protection,service life,and structural principle.However,regular maintenance checks are still necessary to ensure the integrity of the system,especially the electric actuator motor and control module.
• Energy EfficiencyElectromagnetic shock absorbers can improve energy efficiency and reduce the carbon footprint.Its important to monitor the energy consumption and ensure the system is operating at peak efficiency.
• Safety and ReliabilityThe safety and reliability of the shock absorber system are enhanced by the use of ferrofluids in combination with mechanical sealing.Ensure that the ferrofluid is properly contained and that the magnetic field is stable to maintain the seal.
Basic Information
• Function and Energy RecoveryElectromagnetic shock absorbers are designed to dampen vibrations in vehicles,especially due to road roughness.Unlike conventional shock absorbers that dissipate energy as heat,regenerative electromagnetic shock absorbers recover this energy.They come in two configurationslinear and rotary devices.
• Technical SpecificationsKey parameters for electromagnetic shock absorbers include magnetic fluxB_i,frequencyf,forceF,height of pole ringH,currentI,constantK,lengthL,number of turns/mmn,power generatedP,total resistance of coilsR_c,resistance of external loadR_L,velocityv,and voltageV.
• Energy HarvestingThese shock absorbers can generate about 15-20 W of electric power for normal suspension velocities.They can improve fuel efficiency and reduce emissions by converting vibration energy into electricity,which can be used for charging batteries or supplying electrical loads in vehicles.
• Design and AnalysisThe design of electromagnetic shock absorbers involves static magnetic analysis to analyze magnetic field distribution and obtain an optimum design.A preliminary equation is proposed to predict the generation performance based on input parameters like flux or velocity.
• PerformanceTheoretical studies show that 32 watts of power can be recovered from a vehicle moving with 45 mph speed experiencing 0.25 m/s vertical velocity.
