The first step in developing an adaptive solution for influencing the external shape and reducing vibrations, as well as for structure-integrated component monitoring, focuses on experimental and numerical analysis of the structural design.

Based on this, the dynamic system is identified in detail for different operating states and a roadmap for the development of adaptive measures is derived. We accompany you on the way to complete system identification through high-precision software products as well as through our experimental investigations.

Compared to classical methods, active measures for vibration isolation of components have the advantage of adaptability over a wide frequency range.

These measures for optimizing machine behavior (e.g. in rotating machines) and reducing vibrations can be divided into the areas of shape morphing and methods for active vibration control. Shape morphing involves actively influencing the geometric properties of components, which is particularly effective for aerodynamic components. Active vibration reduction attempts to counteract or absorb vibrations that occur during operation via an electromechanical interface.

Integrated component monitoring (usually referred to as structural health monitoring) is based on non-destructive testing of components in service.

In this method, the component is excited by an external source (e.g., a bonded piezo), and possible damage such as cracks or delamination is detected by receiving the response signal using radiation or ultrasonic technology.
