- Development of a semiactive damper for mitigating seat vibration
抄録
<p>The burden of vibration on passengers during vehicle operation is significant, and prolonged exposure can cause vibration problems such as back pain. However, it is difficult for passive dampers to provide good insulation against steady and transient inputs. In this study, we develop a semiactive vibration control method that insulates the vibration by sealing magnetorheological fluid in the damper mounted on the seat suspension and adaptively changing the viscosity according to the magnitude of the magnetic field. The viscosity switching law is based on the skyhook theory, which discriminates the appropriate magnitude of the damping force from the combination of input signals. First, the vibration damping performance is compared using two vibration methods, steady-state excitation and shock input, in a passive state. The effectiveness of the variable viscous damper is then evaluated by simulating a semiactive condition. The results show that the system exhibits the damping characteristics of a 1-DOF vibration system, reducing the vibration by up to 52% at the peak of resonance.</p>
