An advanced process of vibration control of a cantilever plate with help of Finite Element Method
The purpose of this work is to control the vibration of the plate with the help of finite element method. Using augmented equations, a finite element model of a two-dimensional cantilever plate instrumented with a piezoelectric patches sensor-actuator pair is derived. The contribution of piezoelectric sensor and actuator layers on the mass and stiffness of the plate is considered. As mesh size ...
متن کاملVibration Analysis and Control of Cantilever Plate by Using Finite Element Analysis
Mechanical vibrations induced in flexible structures such as beams and plates have been researched through various optimization functions and control theories to optimize transient response dynamic characteristics. Piezoelectric materials sensors/actuators have been used to reduce and control these vibrations. However, stiffened plate has not been investigated and it is a main and important par...
متن کاملbuckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
Vibration Control of Cantilever Beam Based on Eddy Current Damping
A great difficulty is faced in the design of such structures due to the fact that the reduction in weight results in low rigidity and reduced vibration characteristics. Apart from the vibration is effectively controlled; it may destabilize the system and may, very often, result in complete failure of the system. Several advanced applications, such as those in jet fighters, automobiles and space...
متن کاملVibration of Timoshenko Beam-Soil Foundation Interaction by Using the Spectral Element Method
This article presents an analysis of free vibration of elastically supported Timoshenko beams by using the spectral element method. The governing partial differential equation is elaborated to formulate the spectral stiffness matrix. Effectively, the non classical end boundary conditions of the beam are the primordial task to calibrate the phenomenon of the Timoshenko beam-soil foundation inter...
