Vibration Formulas: Frequency, Amplitude & Acceleration

Click For Summary
The discussion focuses on the relationships between frequency, amplitude, and acceleration in vibration formulas. A key point is the correction of the acceleration value from 32.2 ft/s² to 386 in/s² for accurate calculations. This adjustment significantly impacts the results of vibration analysis. Understanding these relationships is crucial for precise engineering applications. Accurate formulas are essential for effective vibration measurement and control.

What are the relationships between frequency, amplitude (double) and acceleration?
 
Physics news on Phys.org
To all, I figured it out myself. I was also using 32.2 ft/ sq.sec when I should have been using 386 in/sq.sec. for my calculations.

Topic about reference frames, center of rotation, postion of origin etc Comoving ref. frame is frame that is attached to moving object, does that mean, in that frame translation and rotation of object is zero, because origin and axes(x,y,z) are fixed to object? Is it same if you place origin of frame at object center of mass or at object tail? What type of comoving frame exist? What is lab frame? If we talk about center of rotation do we always need to specified from what frame we observe?
