KurzbeschreibungDynamics of particles and rigid bodies: Motion of a single particle, motion of systems of particles, 2D and 3D motion of rigid bodies, vibrations
LernzielThis course provides Bachelor students of mechanical and civil engineering with fundamental knowledge of kinematics and dynamics of mechanical systems. By studying the motion of a single particle, of systems of particles and of rigid bodies, we introduce essential concepts such as work and energy, equations of motion, and forces and torques. Further topics include stability of equilibria and vibrations. Examples presented in the lectures and weekly exercise lessons help students learn basic techniques that are necessary for advanced courses and work on engineering applications.
Inhalt1. Motion of a single particle: kinematics (trajectory, velocity, acceleration), forces and torques, active and reaction forces, balance of linear and angular momentum, work-energy balance, conservative systems, equations of motion.
2. Motion of systems of particles: internal and external forces, balance of linear and angular momentum, work-energy balance, rigid systems of particles, particle collisions.
3. Motion of rigid bodies in 2D and 3D: kinematics (angular velocity, velocity and acceleration transfer, instantaneous center and axis of rotation), balance of linear and angular momentum, work-energy balance, angular momentum transport, inertial vs. moving reference frames, apparent forces, Euler's equations.
4. Vibrations: Lagrange equations, single-DOF oscillations (natural frequency, free-, damped-, and forced response), multi-DOF oscillations (natural frequencies, eigenmodes, free-, damped-, and forced response), examples of vibrations in deformable bodies.
