Simulation of Piezoelectric Components with Ansys Mechanical
Electro-mechanical-acoustic simulation fully coupled with the click of a mouse
During this training, you will learn physical principles and will also practice simulating in workshops centered around piezo-acoustic sensors and ultrasonic actuators. This training is offered as a 1-day course.
Duration
1 day
Prerequisites
Basic knowledge of Ansys Mechanical
Software used
Ansys Mechanical
- Understand the physical aspects of electrical/mechanical coupling
- Define piezoelectric material properties in Ansys Mechanical
- Practice static and dynamic piezo effects in exercises
- Design piezoelectric components using simulation
Description
With the introduction of Industry 4.0 and IoT (Internet of Things), the use of piezoelectric components has increased significantly over the last decade. Actuators are used, among other things, in ultrasonic tools to produce electronic bonding connections and for the ultrasonic welding of various plastic components, but also in cleaning devices and active damping elements. Piezo-acoustic sensors are used in various position and level measurement processes as well as in complex driving assistance systems (ADAS).
In this training, you will look at typical static and dynamic excitation conditions of piezoelectric sensors and actuators This enables you to make predictions during the piezoelectric component design stage and to analyze malfunctions. In addition to the necessary physical piezoelectric basics, various workshops will enable you to directly apply what you have learned. Finally, progressing further, more advanced simulation techniques such as model reduction possibilities of piezoelectric components will be discussed.
