Our Motivation
Structural dynamic analyses (e.g., modal analysis) are methods for studying the dynamic properties of structures under various loads and excitations (i.e., periodic, stochastic, impulsive). The analysis includes the identification of natural modes, natural frequencies, and modal damping properties of the structure. This structural dynamics characterization of components is an important part of the design and development process. The main research areas of the institute include:
- Simulation and optimization: modeling of the dynamic structural response to different excitation modes and operating conditions to investigate and improve the properties of lightweight structures based on numerical calculations of vibration models.
- Experimental modal analysis: determination of modal parameters by experimental measurements using shaker or impulse hammer tests, vibration sensors (e.g. accelerometers) and non-contact measurement techniques (e.g. laser Doppler vibrometry).
- Impact and crash testing: methods for evaluating the reliability and resistance of lightweight structures to impact and collision events (e.g., drop tower experiment).
Characterization of these material and component properties enables the development and qualification of novel structures, materials, and designs. As a result, the safety, performance and efficiency of lightweight structures can be ensured and improved.
