VIBRATION ANALYSIS OF BEAMS SUBJECTED TO RANDOM EXCITATION BY THE DUAL CRITERION OF EQUIVALENT LINEARIZATION

INTRODUCTION
Random vibrations are popular in engineering problems such as structures subjected to wind or wave load, bearings or shafts in vechicle components. Under such a loading case, the corresponding vibration model is based on statistical a[r]

Assis and Bueno have written a paper [9] in which he claims Ampère’s law to be consistent with Grassmann’s force law. They derive expressions for the force between the support and the bridge within a set of Ampère’s bridge, using both laws. Conceding that the law[r]

8.1.1 The General Epistemological Predicament Associated to Energy Analysis
Attempts to apply energy analysis to human systems have a long history start- ing with Podolinsky (1883), Jevons (1865), Ostwald (1907), Lotka (1922, 1956), White (1943, 1959), and[r]

The dynamic vibration absorber (DVA) has been widely applied in various technical fields. Using the Taguchi’s method, this paper presents a procedure for designing the optimal parameters of a dynamic vibration absorber attached to a damped primary system. The values of the optimal parameters of the[r]

This paper addresses the strength and deformation capacity of slender columns retrofitted by externally bonded Carbon Fiber-Reinforced Polymers (CFRP) subjected to seismic loading. The behaviour of RC columns depending on the CFRP confinement (carbon CFRP jacket) and on flexural reinforcement (carbo[r]

In case a marine power station is armed with two or more generators, it is frequently required to run them in parallel so as to obtain the continuity and economy of power supply. In respect to A. C. generators, it is allowed for them to be paralleled and[r]

In the present study, the uniformity and potential internal defects of concrete elements in situ were assessed by using Ultrasonic Pulse Velocity (UPV) testing method according to TCVN 9357:2012. Thirteen cross beams with dimension of 4.8 × 1.5 × 1.5 m3 were selected to measure the pulse velocity. T[r]

(25) In this equation there are no suggestions about concrete mechanisms of absorption and
radiation. In this sense it nothing differs from the equations of conservation of energy and an impulse, written by Compton. In connection with such extremely superficia[r]

6.2.4 Study on new shock absorber
Along with the deepening of the research on shock absorber, many new shock absorbers have appeared. Several typical kinds are listed as below:
Yan Jiabin [82] proposed an elastic metal shock absorber, which fixed two disks connected wit[r]

Composite materials have been more and more widely used in many branches of structural engi- neering such as aircraft, ships, bridges, buildings, automobile, etc. due to their dominate advantages in comparison with other types of materials. Composite materials have high strength[r]

A typical example of devices that strongly demand for the availability of reliable behavioral models is represented by the class of digital memories, that are widely used in modern electronic equipments and that are often provided by external supplier[r]

This paper presented a method to reduce the torsional vibration of a shaft system with dynamic vibration absorber (DVA). A theoretical method was introduced to determine optimal parameters of the DVA, which included spring stiffness, viscous coefficient of damper, mass moment of inertia of the absor[r]

Chapter 2 gives appropriate background theory for this book, while Chapter 3 gives a detailed discussion of the two alternative ways the power spectral density can be defined and the equivalence between them. Chapter 4 gives important results that facilitate the der[r]

Analysis of kinetic data Rate constants for APC-catalyzed Arg506 and Arg306 cleavage were obtained as described previously by fitting the time courses of FVa inactivation to a random-orde[r]

Quality of life research can provide the researcher and the clinician with a clearer view of the impact that a cancer treatment has on a patient's life. This is clearly shown on this instrument from the scale that examines the attitude of patie[r]

This thesis aims to develop finite element models for studying vibration of FGM porous beams in thermal environment under moving loads. Both analytical method and finite element analysis are employed in the thesis. The analytical method is used to derive equations of motion for the beam, and the fin[r]

During the startup of a new machine, one should try to identify all the major peaks in the real-time spectrum. If unidentifiable peaks appear, then perhaps the speed should be held constant until a cause for the peak is identified. When a completely n[r]
