In a large number of precision engineering implementations, e.g. actuators, sensors, communication terminals and small motors, the functional elements are based on electromechanical interactions. The engineering description of these electromechanical systems is the focus of the lecture. Starting from the structuring of the electromechanical systems into mechanical or acoustic networks, the interactions are treated in terms of electromechanical transducers. Starting point of the mechanical and acoustic network considerations are analogy relations to linear electrical networks with concentrated parameters.
In the second part, the principles of action as well as the static and dynamic transfer properties of electromechanical transducers are treated. The model description of the coupling of the mechanical and electrical quantities is carried out by loss-free four-pole equivalent circuits. By means of the calculation of device examples from sensor technology, actuator technology and electroacoustics, the clarity and illustrative solution finding with the help of these network considerations is demonstrated.
Peer instruction is used in the exercise. What is Peer Instruction? In short: You teach each other! And here's how it works:
1. You will be given a multiple-choice task. The questions are mainly aimed at understanding, but sometimes knowledge or knowledge transfer is also required.
2. First thought: Everybody tries to solve the problem without help. Calculating is allowed (and required), but for now exchange with fellow students or looking up on the Internet is prohibited – just like in the exam.
3. First anonymous vote: We use the online voting system invote. By Smartphone or SMS you set your solution proposal completely anonymously.
4. Discussion with your fellow students: How did the neighbor solve the problem? Who's right? Issues with the content are best recognized and solved in the discussion. You're learning.
5. Second anonymous vote and comparison of the results: How many of you knew the right answer the first time and what about the discussion? Typically we see a clear tendency towards the right answer.
