Formula Used
Critical Speed = 946/sqrt(Deflection)
Nc = 946/sqrt(δs)
This formula uses 1 Functions, 2 Variables
Functions Used
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)
Variables Used
Critical Speed - (Measured in Revolution per Minute) - Critical Speed its unbalanced mass of the rotating object causes deflection that will create resonant vibration.
Deflection - (Measured in Millimeter) - Deflection is the degree to which a structural element is displaced under a load (due to its deformation).
STEP 1: Convert Input(s) to Base Unit
Deflection: 0.005 Millimeter --> 0.005 Millimeter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula

What is Critical Speed?

An object is said to reach critical speed when the speed of its rotation corresponds to one of its natural frequencies. This type of speed is studied in a branch of physics known as rotordynamics, which deals with rotational, or angular, motion. A rotating object, such as a propeller or a centrifugal pump, must often pass through one or more of its critical speeds as it accelerates or decelerates. While operating at critical speed, these objects vibrate at a high amplitude, which can cause damage.

How to Calculate Critical Speed for Each Deflection?

Critical Speed for Each Deflection calculator uses Critical Speed = 946/sqrt(Deflection) to calculate the Critical Speed, Critical Speed for Each Deflection is defined as the deflection of the shaft due to transverse vibration because the centrifugal forces change direction rapidly as the shaft turns. Critical Speed is denoted by Nc symbol.

How to calculate Critical Speed for Each Deflection using this online calculator? To use this online calculator for Critical Speed for Each Deflection, enter Deflection s) and hit the calculate button. Here is how the Critical Speed for Each Deflection calculation can be explained with given input values -> 127754.9 = 946/sqrt(5E-06).

FAQ
