Eligibility:


In order to be eligible for a second cycle course the applicant needs to fulfil the general and specific entry requirements of the programme that owns the course. (If the second cycle course is owned by a first cycle programme, second cycle entry requirements apply.)
Exemption from the eligibility requirement: Applicants enrolled in a programme at Chalmers where the course is included in the study programme are exempted from fulfilling these requirements.

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 using LabVIEW, Matlab/Simulink and test rigs with modern data acquisition hardware (CompactDAQ, CompactRIO);

-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.

Computer assignments and labproject: The topics will be closed related to the course lectures as well as to the ongoing research projects at the Division of Dynamics with industrial partners (Volvo GTT, Scania, Swedish Wind Power Technological Centre, others).

Syllabus is linked to the UN Global Sustainability Goals. Knowledge within optimization of control and design of modern technical systems to reduce the system weight, energy consumption, vibrations, etc., gives strong ability to everyone to contribute to Global sustainability goals, for example to "Sustainable industry, innovations and infrastructure" (No. 9) and to "Sustainable Energy for All" (No.7).

Organisation

The course will comprise the following type of activities: lectures, problem solving sessions, computer assignments on vibration dynamics and control with MATLAB/Simulink, and Lab's project on experimental validation of vibration control methods at the Vibrations and Smart Structures Lab of the division of Dynamics.
