The purpose of this research is to build a dynamic model to describe the behaviour of a hopper under forced vibration. Since a dosing hopper operates under forced oscillations (vibration) to achieve a uniform distribution of the sown material, oscillations that take place in particular units and in the mechanisms cannot be neglected.
The model allowed for tire inflation and static loading and also allowed for both free and forced vibration analysis.
The behavior of a structure under earthquake conditions is a dynamic problem because the seismic movement causes forced vibration in it.
Resonance and flutter produced by the forced vibration and self-excited vibration are the main reason leading to the blade failure.
The effectiveness of the linear quadratic regulator and flexible mode shape method based optimal control techniques on controlling transient and forced vibration responses of a fully and partially treated MR fluid sandwich were investigated by Vasudevan et al.
On the basis of (18), a parametric resonance will occur when [[omega].sub.p] [approximately equal to] 2[[omega].sub.s, whereas a forced vibration will occur when [[omega].sub.p] [approximately equal to] [[omega].sub.s.
Green's function has high precision and computational efficiency in the forced vibration analysis of beam [14,15].
Nahidh Mahmood [6] investigated experimentally and numerically the response of a conduit (thin wall pipe) conveying fluid due to a forced vibration. Several end pipe supports, like fixed-fixed, pinned-pinned, fixed-free and flexible-flexible were adopted.
This paper describes the results of a reliability analysis of the South Grandstand of the Pascual Guerrero Olympic Stadium in the city of Cali, Colombia, using ambient and forced vibration records and model updating techniques based on anthropic loads.
Forced vibration of Euler-Bernoulli beams by means of dynamic Green functions.
Ideal for conveying pharmaceutical finished products and ingredients and other delicate materials, the conveyors feature the company's own forced vibration drive system to create a gentle, efficient, linear conveying action suitable for low-maintenance, 24/7 operation.
