the external force for this case (ground excitation) is zero. ff f 0ID S+ += Only relative displacements u between masses and the base produce deformation and elastic and damping forces. 11 25 The inertia forces fI are related to the total acceleration ut. t fmuI = Substituting t
1 CHAPTER 17 VIBRATING SYSTEMS Introduction A mass m is attached to an elastic spring of force constant k, the other end of which is attached to a fixed point. The spring is supposed to obey Hooke's law, namely that, when it is extended (or compressed) by a distance x from its natural length, the tension (or thrust) in the spring is kx, and the equation of motion is mx = − kx.

The Vibrating Conveyor For Incinerator Ash For. The springmass system in the vibrating conveyor, in its simplest form, comprises the conveyor trough and associated "live" structure, springs made of some elastic material such as steel, rubber, or fiberreinforced plastic laminates, a means for applying a small periodic impressed force, and a fixed base against which the spring force reacts
Harmonic Excitation Force input function of the harmonic excitation is the harmonic function, functions of sines and cosines. This type of excitation is common to many system involving rotating and reciproing motion. Moreover, many other forces can be represented as an infinite series of harmonic functions. By the principle of

the magnetic body, generating a constant pulling force between magnetic body and armature. When an ACvoltage is applied to the excitation winding the force effect of the electromagnetic alternating field is superimposed on the force effect of the permanent magnet. In order to achieve the vibrating movement desired the useful
• Isolation rearranges the excitation forces to achieve some reduction or cancellation. • Damping is the conversion of mechanical energy (vibrations) into heat. For the simple vibrating system (single degree of freedom), shown in Figure 1A, below, the force input is comprised of 3 distinct components; stiffness, damping, and inertia.

The force produced by an exciter is mainly limited by the heating effect of the current. the RMS value. whereas the power amplifier rating is influenced by the peak values. To give the same force the amplifier must therefore be larger when used with random than with sine excitation. The random spectrum is described by its power spec
