Modal Analysis Turboshaft Test Stand Motor Designed by Using ANSYS

Today, modeling is critical for cognition and analysis of designers in industry field to meet their needs and design based on design requirements and available facilities to accelerate production and development of components of industrial engines. In this study, one structure has been proposed, designed, and analyzed based on turboshaft marine engine type to test this kind of engine in order t...

Experimental Modal Analysis

SOUND AND VIBRATION/JANUARY 2001 Often times, people ask some simple questions regarding modal analysis and how structures vibrate. Most times, it is impossible to describe this simply and some of the basic underlying theory needs to be addressed in order to fully explain some of these concepts. However, many times the theory is just a little too much to handle and some of the concepts can be d...

Basics of Experimental Modal Analysis

The development of a modal model, from either frequency response measurements or from a finite element model, is useful for simulation and design studies. One of these studies is structural dynamics modification. This is a mathematical process which uses modal data (frequency, damping and mode shapes) to determine the effects of changes in the system characteristics due to physical structural c...

Test Selection Criteria for Modal Speci cations of Reactive Systems

In the framework of functional testing from algebraic speci cations, the strategy of test selection which has been widely and e ciently applied is based on axiom unfolding. In this paper, we propose to extend this selection strategy to a modal formalism used to specify dynamic and reactive systems. Such a work is then a rst step to tackle testing of such systems more abstractly than most of the...
