Analysis of An Adaptive Vibration Absorber in Robotics Using Ferrofluid

Damping of an abrupt shock implies through a mechanical device and dissipate shock into kinetic energy by a device turn shock absorbable designed for smoothness. In case of mobile robots, travelling over uneven ground results in generation of shocks which are reduced by a damping control over excessive suspension movement in lack of shock absorption requires high grade springs which increase the overall cost of the system; thus, an efficient and cost-effective damping system is needed. The authors tested various piston and cylinder shapes for the design of an optimum damper using ferrofluid. To get the highest range of damping force testing of ferrofluid (EHF1) using a rheometer at constant shear rate of 10 was done. The ferrofluid based damping system has the ability to vary its damping force according to the electrical actuation thereby making such dampers very versatile in use.
