Forced vibration of damped, single degree of freedom, linear spring mass systems. Finally, we solve the most important vibration problems of all. In engineering practice, we are almost invariably interested in predicting the response of a structure or mechanical system to external forcing. For example, we may need to predict the response of a bridge or tall building to wind loading ...

The traditional method of dynamic calculation of blasting vibration response of buildings has low accuracy. For this reason, a dynamic calculation method of building blasting vibration response based on differential equation is designed. The information contained in the original time domain is converted into the frequency domain by Fourier transform, and then the intensity index of blasting ...

In the case of a simple vibrating system, the dynamic amplification factor has a value of 2,, the loading due to the oscillations resulting from a sudden application of a weight is twice as severe as the loading that would be obtained if the weight were applied quasistatically without creating oscillations. For more complicated vibrating systems, the value of the dynamic amplification ...

The vibrating screen from which the springs were taken presents two types of loading over them: the first, a static load due to the weight of its components and the material it processes; the second, a dynamic load due to the exciters that produce the screen vibration. The combined effect of both types of loading causes the stress amplitude to oscillate symmetrically around the static stress ...

The subject of vibration is introduced here in a relatively simple manner. The chapter begins with a brief history of vibration and continues with an examination of its importance. The various steps involved in vibration analysis of an engineering system are outlined, and essential definitions and concepts of vibration are introduced. We learn here that all mechanical and structural systems ...

The screens with vibrating sieves are designed first of all for screening of fine and very fine granular materials. They are characterized by relatively high dynamic factors. That is why in these machines layers on the sieve are well segregated and high screening efficiency is achieved. The screens with vibrating sieves are characterized by high frequency of vibrations and small amplitudes. In ...

vibration of machines that are mounted on floors or walls. Obviously, the best place to mount a vibrating machine is on the ground floor. Unfortunately (but fortunately for noise control consultants), this is not always possible. A typical problem is a rotating machine (such as a pump, AC compressor, blower, engine, etc) mounted on a roof, or on a floor above the ground floor. The problem is ...
