Laser Doppler vibrometry (LDV) is currently the method that offers the best displacement and velocity resolution and is used in many fields of basic science. It enables femtometer amplitude resolution and is linear and therefore has a consistent amplitude right up to the very high frequency ranges – practically reaching more than 2 GHz at present. These properties are independent of the measuring distance, so this principle is used both in microscopic operations and over very large distances. Light as a sensor does not influence the sample, making it non-invasive and therefore enabling measurements to be carried out on extremely small and extremely lightweight structures. Since this procedure offers such unbeatable properties, Polytec has made it robust and fit for use in both the laboratory and outdoors. The Laser Doppler Vibrometer (LDV) has been associated with several test platforms related to Active and Passive Vibration Control.

• For the UG students, two test set-ups are developed for testing of Vibration Response of 2D Plates related to all the classical boundary conditions that is Fixed-Free-Fixed-Free, Cantilever, Fixed-Free-Hinged-Free, all clamped and all hinge conditions. Through a forced exciter, the students could study the harmonic excitation responses of rectangular plates.

• For the PG students, the same test set-up is used for the testing of symmetric and asymmetric laminated composite plates. An extension for active vibration control has been developed where SMA wires attached to the plate provide initial stress to the plates and thus the influence of active strain on the dynamic response is being studied.

In recent years, the new technologies for the visualization of sound sources - Acoustic Camera - have become extraordinarily relevant in industry and the environmental sector due to their practical and intuitive use, providing engineers with a great new opportunity: " Seeing sound sources with your eyes . ” Powerful and flexible, it makes sound and vibration visible in real time.

It is easy to use for non-acoustic experts and offers great functionality for professionals. It can be adapted to your needs thanks to the its flexibility in array design, number of microphones and state of the art algorithms. Being able to switch between beamforming, holography and sound intensity measurements allows you to analyze a wide range of objects.

Graphics Processing Units (GPUs) have rapidly evolved to become high performance accelerators for data-parallel computing. Modern GPUs contain hundreds of processing units, capable of achieving up to 1 TFLOPS (trillion floating point operations per second) for single-precision (SP) arithmetic, and over 80 GFLOPS (billion floating point operations per second) for double-precision (DP) calculations. Recent high-performance computing HPC-optimized GPUs contain up to 4GB of on-board memory, and are capable of sustaining memory bandwidths exceeding 100GB/sec. The parallel hardware architecture and high performance of floating point arithmetic and memory operations on GPUs make them particularly well-suited to many of the same scientific and engineering workloads that occupy HPC clusters, leading to their incorporation as HPC accelerators.

Mide’s Piezo Protection Advantage (PPA) standard products utilize the piezoelectric effect to convert mechanical energy in the form of vibration or shock into electrical energy. All of the PPA products can be tuned to a wide range of frequencies. Adding tip mass dramatically reduces the resonant frequency, and further adjustment can be made by changing the clamp location. The piezo beams can be clamped on both ends or bonded to a stiffer beam to increase the resonant frequency.
