SolidWorks Professor - Dynamic Analysis for Vibration Testing in SolidWorks Simulation Premium. SolidWorks Simulation - Natural Frequencies, Mode Shapes & Vibration Tutorial. Resonating to the Harlem Shake - SolidWorks Simulation. Back in early February, a new internet sensation swept the world via YouTube called the “Harlem Shake”.
For those who aren’t familiar with it, you can do some cultural catch-up here. When I saw these videos, the inner nerd in me started thinking about natural frequencies and resonance which are both based on the standard single degree of freedom (DOF) mass-spring system: To calculate the natural frequency of this system, the equation below is used where k is the spring stiffness in Newtons/meter, m is the mass in kilograms, and ω is the natural frequency in radians/second. How does this translate to SolidWorks Simulation? The first thing we would need is SolidWorks Simulation Professional, which includes the frequency analysis study type.
Second we need a model to represent this single DOF mass-spring problem. Finally we need to mesh the problem before running it. After running the simulation, the first natural frequency is shown to be 0.31622 rad/s. Frequency Studies in SolidWorks Simulation Professional by Brian Zias. Frequency Studies in SolidWorks Simulation Professional by Brian Zias Intro Every product is subject to real-world conditions that ultimately cause failure in one way or another.
: The Importance of Frequency Analysis. Have you heard the buzz about running a frequency analysis on your assemblies?
Actually… if you've heard a buzz at all, frequency was the reason. Theory of Vibration. PRSG027: How To Analyze Noise & Vibration From Rotating Machinery (Complete) Fourier Transforms. Introduction "Lies, Damn Lies, and Statistics.
" Few people appreciate statistics. But at least they seem OK with this and don't go off starting religious wars over the subject. Alas, such is not the case with Fourier transforms. Fourier Series.

Signal integrity or SI is a set of measures of the quality of an electrical signal.
In digital electronics, a stream of binary values is represented by a voltage (or current) waveform. However, digital signals are fundamentally analog in nature, and all signals are subject to effects such as noise, distortion, and loss. Over short distances and at low bit rates, a simple conductor can transmit this with sufficient fidelity. At high bit rates and over longer distances or through various mediums, various effects can degrade the electrical signal to the point where errors occur and the system or device fails. Signal integrity engineering is the task of analyzing and mitigating these effects. History Signal integrity primarily involves the electrical performance of the wires and other packaging structures used to move signals about within an electronic product.

Voltage, Current, Power & Energy : Definitions. Last Modification: February 17, 2013 Connecting a measurement instrument in the right way only is one thing.
But, to determine the correct parameter needs more considerations. Very important is the question: For what purpose do I do this measurement? Performing a current measurement to examine the heat development in a wire requires a different parameter than a current measurement to determinate the charge status of a capacitor or battery. Parameters can be expressed as an average, RMS, instantaneous or peak value. SolidWorks Premium is the right choice for Design Engineers that need everything. How is Machine Vibration Described? By Commtest Instruments To analyze the condition of a machine you first need to accurately describe the behavior or symptoms of the machine.

Power spectral density (PSD), which describes how the power of a signal or time series is distributed with frequency.
Here power can be the actual physical power, or more often, for convenience with abstract signals, can be defined as the squared value of the signal, that is, as the actual power if the signal was a voltage applied to a 1-ohm load.
