Course specific prerequisites
Basic knowledge in mechanics, in particular dynamics of particles and rigid bodies¿ plane motion, some familiarity with state space models and automatic control.Aim
The course aims at providing knowledge on modern methods and concepts of passive, semi-active and active vibration control, to cross the bridge between the structural dynamics and control engineering, while providing an overview of the potential of smart materials, (magnetorheological fluids, magnetostrictive materials, and piezoceramics), for sensing and actuating purposes in active vibration control. Vibration control applications appear in vehicle engineering, high precision machines and mechanisms, robotics, biomechanics and civil engineering. The focus of the project part of the course is on experimental validation of practical methods, i.e., methods that were found to actually work efficiently for passive and/or active vibration control. The course prepares students to use industry-leading data acquisition hardware and software tools for measurement, signal processing and vibration control.Learning outcomes (after completion of the course the student should be able to)
-Derive the equations and solve vibration dynamics problems for controlled multibody systems with springs, dampers and bushings;
-Create mathematical and computational models suitable for structural dynamics control applications;
-Analyze vibration dynamics, dynamic responses of structural systems for different damping concepts and external control;
-Explain in detail the basic principles on which the structural dynamics control methods rely and choose appropriate control strategy for particular applications;
-Formulate and solve passive, semi-active as well as active structural dynamics control problems for vibrating mechanical systems;
-Evaluate vibration control solutions experimentally by test rigs with modern data acquisition hardware and software;
-Understand, explain and apply the physics behind semi-active and active structural dynamics control solutions based on smart materials sensor and actuator technologies (magnetorheological fluids, magnetostrictive and piezoelectric materials);
-Carry out structural dynamics analysis and design vibration control strategies for vibrating systems having applications in automotive industry (chassis and powertrain suspensions), railway industry (high speed train bogie and car-body suspensions), wind power industry (turbine drive train systems), civil engineering;
-Understand that vibrations can be also used for advantage in some applications. Know the basic principles and the state of the art on vibration to electrical energy conversion by using smart materials (power harvesting technology);
-Show ability to work in project team and collaborate in groups with different compositions.
