Analysis of Machinery, Mechanical Vibrations and Acoustics

Eidos Engineering Eidos Engineering is an engineering company offering engineering service and innovative anti-vibration devices. Eidos Engineering is established in the technological center “Polo Tecnologico di Pordenone Andrea Galvani” in Pordenone (Italy).

Vibrations, noise and dynamics how to turn problems into opportunities For many companies, problems related to mechanical vibrations, noise and dynamics have a significant influence on the quality, reliability and conformity with the standards and specifications expressed by customers. Often, the solution of these problems involves time and cost also because of the absence, in the company staff, of a figure possessing the necessary skills. Eidos Engineering, technical study of the leading experts in the field of mechanical vibrations, noise and dynamics, provides the following services:  Dynamics of machinery  Mechanical vibrations  Acoustics  Design and supply of mass dampers  Numerical analysis and simulation  Experimental analysis  Training

Simulation and Numerical Analysis

Finite element analysis Structural, modal and fatigue analysis, to a complete development of the components of machines.

Multi-body dynamics Eidos applies its knowledge on several kind of problems such as the analysis of articulated joints (i.e. diggers, robots,...) or in the development of high speed mechanisms (i.e. centrifuge).

Dynamics of structures Displacement [m] Vibration of structure Time [s] Friuli 1976 – Buja seismic station Displacement of the structure at top Dynamic analysis of a three stories structure. The graph shows the displacement of top of the structure under the 1976 Friuli earthquake.

Finite element acoustics Nowadays, acoustic standards increasingly demanding. are Washing machine cabinet vibration Strictly related to the vibration analysis, the predictions of noise emissions is the result of the application of the rights techniques. Eidos moves through different methods, such as FEA and experimental analysis, to better outline the problems and find out the solutions.

Experimental Analysis

Frequency response The first way to investigate the behaviour of a system is to measure its frequency response function. It may be found out by impulse hammers or by vibro-dynamic exciters. Vibro-dynamic exciter on a tool machine
