Frequency response analysis is an extension of modal analysis in some way. If you want to know about modal analysis, the full article is here: http://feaforall.com/what-modal-analysis-fea-basics/ In short, modal analysis helps to determine the modes of vibrations and the frequencies at which those modes are triggered, BUT modal analysis doesn’t give you any info about the real deformation that an excitation of one of those modes will actually cause. When you have to do a dynamic analysis, modal analysis is only the beginning! Some modes will cause more « resonance » than others (and thus more damage)… so we want to know which ones and we want also to calculate the maximum deformation for each of the modes « triggered ». Go on the blog to read the full explanation: http://feaforall.com/frequency-response-analysis-fea/

What is MODAL ANALYSIS? What does MODAL ANALYSIS mean? MODAL ANALYSIS meaning - MODAL ANALYSIS definition - MODAL ANALYSIS explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Modal analysis is the study of the dynamic properties of systems in the frequency domain. A typical example would be testing structures under vibrational excitation. Modal analysis is the field of measuring or calculating and analyzing the dynamic response of structures and/or fluids or other systems during excitation. Examples would include measuring the vibration of a car's body when it is attached to an electromagnetic shaker, analysis of unforced vibration response of vehicle suspension, or the noise pattern in a room when excited by a loudspeaker. Modern day experimental modal analysis systems are composed of 1)sensors such as transducers (typically accelerometers, load cells), or non contact via a Laser vibrometer, or stereophotogrammetric cameras 2) data acquisition system and an analog-to-digital converter front end (to digitize analog instrumentation signals) and 3) host PC (personal computer) to view the data and analyze it. Classically this was done with a SIMO (single-input, multiple-output) approach, that is, one excitation point, and then the response is measured at many other points. In the past a hammer survey, using a fixed accelerometer and a roving hammer as excitation, gave a MISO (multiple-input, single-output) analysis, which is mathematically identical to SIMO, due to the principle of reciprocity. In recent years MIMO (multi-input, multiple-output) have become more practical, where partial coherence analysis identifies which part of the response comes from which excitation source. Using multiple shakers leads to a uniform distribution of the energy over the entire structure and a better coherence in the measurement. A single shaker may not effectively excite all the modes of a structure. Typical excitation signals can be classed as impulse, broadband, swept sine, chirp, and possibly others. Each has its own advantages and disadvantages. The analysis of the signals typically relies on Fourier analysis. The resulting transfer function will show one or more resonances, whose characteristic mass, frequency and damping can be estimated from the measurements. The animated display of the mode shape is very useful to NVH (noise, vibration, and harshness) engineers. The results can also be used to correlate with finite element analysis normal mode solutions.

What exactly is the difference between the time domain and frequency domain? And what about the frequency domain tells us more about our signal? In this video we have the same signal going to an oscilloscope and a signal analyzer, both being tools to visualize electrical signals in the time and frequency domain respectively. Typically the higher the frequency, the more waves we see in the same span on our oscilloscope. In the time-domain, signals appear as sinusoidal waves and in the frequency-domain they appear as distinct impulses. But why do we care to use a signal analyzer? In a perfect world we would see the undistorted sinusoidal waveform like we would see on an oscilloscope, but we don’t live in a perfect world. When dealing with various devices it’s often you see a not so perfect, distorted sine wave with many ripples. You can say that a real-world signal can be represented as a sum of different sinusoid signals, or rather different frequencies. Now let’s say you’re designing a product and your product can only operate in a specified bandwidth and can’t be emitting in other bandwidths. Then you must determine at what other frequencies do the other signals exist that are corrupting the signal you want from your device And that’s where signal analyzers come in – they help separate and display this combination of different sinusoid signals into their distinct frequency components … so that if you were expecting your device to operate at a certain frequency you can see all the other frequencies that are messing with your device. And once that’s figured out you can use a band-pass filter to tune out those annoying extra signals you weren’t expecting – hence the benefit of seeing signals in the frequency domain! Tune in for future What The RF (WTRF) episodes covering more spectrum analyzer capabilities and fundamental measurements to see how you can test more efficiently!

Frequency response analysis, or FRA, is a powerful tool to ensure the integrity of a power transformer. It is typically used to detect if the core and winding assembly has electrically or geometrically changed due to a short-circuit fault or a relocation. Furthermore it is used for routine diagnostic measurement, and for further diagnosis, if routine testing or monitoring identify irregularities. Get more information: http://www.omicron.at/franalyzer/

RESPONSE SPECTRUM METHOD: The representation of maximum response of idealized single degree freedom system having certain period and damping, during earthquake ground motions. This analysis is carried out according to the code IS 1893-2002 (part1). Here type of soil, seismic zone factor should be entered from IS 1893-2002 (part1). The standard response spectra for type of soil considered is applied to building for the analysis in ETABS 2013 software.The standard response spectrum for medium soil type and that can be given in the form of time period versus spectral acceleration coefficient (Sa/g). Response spectrum for medium soil type for 5% damping This approach permits the multiple modes of response of a building to be taken in to account (in the frequency domain). This is required in many building codes for all except very simple or very complex structures. The response of a structure can be defined as a combination of many special shapes (modes) that in a vibrating string correspond to the “harmonic” computer analysis can be used to determine these modes for a structure. For each mode, a response is read from the design spectrum, based on the modal frequency and the modal mass, and they are then combined to provide an estimate of the total response of the structure. In this we have to calculate the magnitude of forces in all directions i.e. X, Y & Z and then see the effects on the building. Combination methods include the following: • absolute - peak values are added together • square root of the sum of the squares (SRSS) • complete quadratic combination (CQC) - a method that is an improvement on SRSS for closely spaced modes The result of a response spectrum analysis using the response spectrum from a ground motion is typically different from that which would be calculated directly from a linear dynamic analysis using that ground motion directly, since phase information is lost in the process of generating the response spectrum. In cases where structures are either too irregular, too tall or of significance to a community in disaster response, the response spectrum approach is no longer appropriate, and more complex analysis is often required, such as non-linear static analysis or dynamic analysis.
