Parameter Identification of Vibrating MIMO Mass-Spring-Damper Mechanical Systems with Coulomb Friction
Abstract: This study presents a time-domain method for identifying parameters in multi-degree-of-freedom (DOF) linear mass-spring-damper systems that include Coulomb friction, where the friction coefficient varies within a limited range, using measurements of position and control force. For mass identification in single-degree-of-freedom (DOF) vibrating mechanical systems with stiffness and no damping but Coulomb friction, the friction term is eliminated by first derivative processing. In addition, the identification of the coefficient of friction …

Electromagnetic Damping in Shock Absorbers
Abstract: In the shock absorber, springs are used as dampers which hold the weight of vehicle, rider(s), and cargo. After certain interval of time, the stiffness of the spring gets reduced due to some parameters e.g. load, oscillation, etc.; because of that, there will be imbalance in the vehicle, which would lead to loss of control and hence major accident. In order to prevent such untorn events, I will present some …
