What is undamped free vibration?
The simplest vibrations to analyze are undamped, free, one degree of freedom vibrations. "Undamped" means that there are no energy losses with movement (whether intentional, by adding dampers, or unintentional, through drag or friction). An undamped system will vibrate forever without any additional applied forces.
How to Calculate Phase Constant?
Phase Constant calculator uses Phase Constant = atan((Damping Coefficient*Angular Velocity)/(Stiffness of Spring-Mass suspended from Spring*Angular Velocity^2)) to calculate the Phase Constant, The Phase constant formula tells how much a signal is shifted along the x-axis. A phase constant of ϕ means that each value of the signal happens ϕ amount of time earlier. Phase Constant is denoted by ϕ symbol.
How to calculate Phase Constant using this online calculator? To use this online calculator for Phase Constant, enter Damping Coefficient (c), Angular Velocity (ω), Stiffness of Spring (k) & Mass suspended from Spring (m) and hit the calculate button. Here is how the Phase Constant calculation can be explained with given input values -> 3604.678 = atan((5*10)/(60-0.25*10^2)).
