Univ., Xian 710072, China 2 Xidian Univ., Xian 710071, China Abstract: By adopting the thought of Adomians decomposition method, the common dynamic models in mechanical systems are transformed into standard first-order-differential-equations, and then the A-operator method (AOM) for the approximate analytic solution of nonlinear mechanical system is developed based on the exact solution in form. The symbolic-numeric (S-N) method on the basis of the AOM is proposed for the first time. Finally, the dynamic responses of one-degree and two-degree nonlinear cam-follower systems are investigated using the AOM. Numerical examples show that AOM is of high accuracy and high efficiency for solving nonlinear equations. It is shown that the method is of potential application value in the nonlinear dynamic analysis of mechanical systems.(8 refs) Main heading: Nonlinear systems Controlled terms: Dynamic mechanical analysis - Dynamic response - Efficiency - Nonlinear equations Uncontrolled terms: A operator method - High accuracy - Nonlinear mechanical system - Symbolic numeric method Classification Code: 731.1 Control Systems - 921.1 Algebra - 931.2 Physical Properties of Gases, Liquids and Solids Treatment: Theoretical (THR) Database: Compendex Full-text and Local Holdings Links 2、Multiple scales analyses of the dynamics of weakly nonlinear mechanical systems Cartmell, M.P.1; Ziegler, S.W.2; Khanin, R.1; Forehand, D.I.M.1 Source: Applied Mechanics Reviews, v 56, n 5, p 455-491, September 2003; ISSN: 00036900; DOI: 10.1115/1.1581884; Publisher: American Society of Mechanical Engineers Author affiliations: 1 Department of Mechanical Engineering, University of Glasgow, G12 8QQ, United Kingdom 2 Department of Mechanical Engineering, UMIST, Sackville Street, Manchester M60 1QD, United Kingdom Abstract: This review article starts by addressing the mathematical principles of the perturbation method of multiple scales in the context of mechanical systems which are defined by weakly nonlinear ordinary differential equations. At this stage the paper investigates some different forms of typical nonlinearities which are frequently encountered in machine and structural dynamics. This leads to conclusions relating to the relevance and scope of this popular and versatile method, its strengths, its adaptability and potential for different variant forms, and also its weaknesses. Key examples from the literature are used to develop and consolidate these themes. In addition to this the paper examines the role of term-ordering, the integration of the so-called small (ie, perturbation) parameter within system constants, nondimensionalization and time-scaling, series truncation, inclusion and exclusion of higher order nonlinearities, and typical problems in the handling of secular terms. This general discussion is then applied to models of the dynamics of space tethers given that these systems are nonlinear and necessarily highly susceptible to modelling accuracy, thus offering a rigorous and testing applications case-study area for the multiple scales method. The paper concludes with comments on the use of variants of the multiple scales method, and also on the constraints that the method can bring to expectations of modelling accuracy.

Edwardsville, Edwardsville, IL 62026-1805, United States 2 BEI Technologies Inc., 2700 Systron Drive, Concord, CA 94518, United States Abstract: The natural frequency and responses of a micro-electro-mechanical system (MEMS) with time-varying capacitors are determined under an equivalent direct current (DC) voltage. Under alternating current (AC) voltages, the resonant condition and the corresponding resonant motion possessing a wide energy band for such a system are investigated because the motion with the wide energy band is very easily sensed. For a given voltage strength, the AC frequency band is obtained for chaotic resonant motions in the specific resonant layer. The numerical and analytical predictions of such a motion are in a acceptable agreement, and the dynamic model provides the range prediction of the alternating current and voltage on the capacitor agreeing with experimental measurements. The lower-order resonant motion has a higher energy than the higher-order resonant motions, which indicates that the lower-order resonant motion can be easily sensed. Although this model is developed from a specified MEMS, the analysis and results can be applied to other dynamic systems. 2004 by ASME.(17 refs) Main heading: Dynamics Controlled terms: Capacitors - Chaos theory - Dynamic response - Electric potential - Equations of motion - Mathematical models - Microelectromechanical devices - Natural frequencies Uncontrolled terms: Alternating current voltages - Chaotic resonant motions - Dynamic model - Equivalent direct current voltage - Time varying capacitors Classification Code: 601.1 Mechanical Devices - 701.1 Electricity: Basic Concepts and Phenomena - 704.1 Electric Components - 751.1 Acoustic Waves - 921.2 Calculus - 931.1 Mechanics Treatment: Theoretical (THR) - Experimental (EXP) Database: Compendex Full-text and Local Holdings
