Abstract A frequency response analysis for a rotating cantilever beam is presented in this study. The equations of motion are derived from Hamilton's principle. An assumed mode method used analyzing the vibration characteristic. transformed into dimensionless forms which parameters identified. effects angular speed investigated through numerical With coupling effect ignored, results consistent with obtained by conventional method. As increases, bending natural frequencies increase...
Dynamical behaviors of a two-degree-of-freedom (TDOF) vibro-impact system are investigated.The theoretical solution periodic-one double-impact motion is obtained by differential equations, periodicity and matching conditions, the Poincaré map established.The dynamics studied with special attention to Hopf bifurcations impact in nonresonance, weak resonance, strong resonance cases.The bifurcation theory maps ޒ 2 -strong applied reveal existence system.The analyses verified numerical...
Abstract Stability periodic motions, saddle-node, grazing and doubling bifurcation conditions for the single-degree-of-freedom impact oscillator are determined analytically numerically. The regions such condition developed in parameter space. Poincaré map of system is established. period-1 motion its stability studied by analytical methods, physical origin hysteresis found as function drive amplitude. To understand rich dynamical behavior system, some numerical methods applied. phase...
Extensive modeling and simulation of the damping phenomenon, electrostatic actuation, structural vibration analysis are performed. The governing partial differential equations cantilever plate obtained, resonant frequencies calculated from equilibrium equations. forces squeeze film analyzed by obtaining ratio spring constant. Electrostatic actuation is applied to oscillate ensure that displacement above thermal noise floor. actuating forces, displacement, capacitance both numerically...
This article introduces the application of image recognition technology in cement pavement crack detection and put forward to method for determining threshold about grayscale stretching. algorithm is designed binarization which has a self-adaptive characteristic. After preprocessed, we apply 2D Wavelet Laplace operator process image. According characteristic pixel gray image, an on Binary The feasibility this can be verified processed by comparing with results three algorithms: Otsu method,...
In this study, we propose a Masreliez–Martin fractional interpolatory cubature Kalman filter and an adaptive to design the estimators for fractional-order discrete-time nonlinear systems under non-Gaussian measurement noise unknown process covariance. Ther is developed by extending discrete system increase robustness of estimation noisy environment applying method, including both time update update. Meanwhile, put forward enhance state with uncertain through recursive estimation. Simulation...
In this study, we put forward the robust fractional gain based interpolatory cubature Kalman filter (FGBICKF) and adaptive FGBICKF (AFGBICKF) for development of state estimators stochastic nonlinear dynamics system. introduces a to increase robustness estimation. AFGBICKF is developed enhance estimation system with unknown process noise covariance through recursive The simulations on re-entry target tracking have shown that performance superior filter, standard deviation closer posterior...
