- 1PE1/2*kx^2
- 2KE1/2*mv^2
- 3Spring Force Equation
- 4—
- 5Single DOF - Spring Eqn
- 6Single DOF Shaft and Disk
- 7SIngle DOF Pendulum
- 8k(static displacement)
- 9m_eq=? J_eq=?
- 10Damped Natural FrequencyThe frequency at which a system vibrates after an initial displacement.
Energy dissipates over time due to dampener.
No external forces - 11Free VibrationsThe frequency at which a system vibrates after an initial disturbance.
No energy loss due to friction or other forces.
No external forces.
HomoG ODE - 12Forced VibrationA system that vibrates and is exposed to a repeated external force. If external force coincides with natural frequency, resonance occurs.
Non-HomoG ODE - 13Non-Steady Random ViabrationA vibration which cannot be predicted. The process can be described by statistical methods. Statistical means vary over time.
- 14Deterministic VibrationVibration which can be predicted. Described by an explicit function of time.
- 15Linear VibrationsIf all the basic components of a vibratory system behave linearly, then the differential equation of the system is linear.
The principle of superposition holds. - 16Non-Linear VibrationsIf all basic components of a vibratory system behave non-linearly, then the differential equation is non-linear.
The principle of superposition does not hold - 17Degree of FreedomDescribes a direction of translation either up/down, left/right, in/out. Or rotation about the x, y, or z-axis, yaw, pitch, roll.
- 18Homogeneous ODERepresents a free vibration
- 19Non-homogeneous ODERepresents a forced vibration
