Operating Frequency Limits specify the range of the load considered in the simulation. Number of frequency points has the same function in random vibration analysis as in the harmonic study. The solution from the random vibration study for any quantity will feature valleys and distinct peaks with the maximums of the response amplitudes. Random vibration … Continue reading Note: Random Vibration Analysis Properties in SolidWorks Simulation

SolidWorks Simulation: Important Concepts in Random Vibration Analysis
Random vibration analysis is useful in solving complex vibration problems. Examples of non-deterministic loads include: Loads generated on the wheel of a car travelling on a rough road Base accelerations generated by earthquakes The pressure generated by air turbulence Pressure from sea waves or strong wind Random vibration analysis provides probabilistic information about output such … Continue reading SolidWorks Simulation: Important Concepts in Random Vibration Analysis
SolidWorks Simulation: How Do We Understand Response Spectrum Analysis?
Any loading can be understood as transient, but it can also be understood as a spectrum of waves. Treating dynamic problem inputs and outputs as a combination of waves (or wave spectrum) simplifies the problem by removing the concept of time. However, the solution is approximate and with certain limitations. You can use a response … Continue reading SolidWorks Simulation: How Do We Understand Response Spectrum Analysis?
SolidWorks Simulation: How Do We Understand Harmonic Response Analysis?
What is harmonic response analysis? Let's start this post by a simple example: A single degree of freedom oscillator loaded with a time varying force F. The solution to this problem is known in closed form. If the force F oscillates, the resulting displacement will oscillate in the same oscillatory fashion. The phase angle Φ, … Continue reading SolidWorks Simulation: How Do We Understand Harmonic Response Analysis?
