Finite Element Modeling of a Vibrating Touch Screen Actuated by Piezo Patches 49 Our group designs a touch screen actuated by piezo patches for displaying vibro- tactile haptic feedback to the user. One of the challenges in the design is the selection of appropriate boundary conditions and the piezo configurations on the screen for achieving ...
Abstract The large-scale and modular design of vibrating screen brings about the trend that the screen separate from screen frame. The separation of the screen frame and the screen changes their dynamic characteristics. By making modal analysis and harmonic response analysis in ANSYS, the dynamic data of the screen and the screen frame was obtained, such as the natural frequencies,

Sep 01, 2012 Natural frquency of a large vibrating screen. 2. I modeled a large vibrating screen in ANSYS to determine the stress. I did a static model simulating the vibrations as acceleration and it was fine to find the stress. Now I need to determine the natural frequency and I found 0,739 as a result and I have no ideia if it could be wrong.
The finite element model of the combined vibrating screen was established by using ANSYS. Modal characteristic analysis and static analysis on the whole unit of screen box were done, and natural frequencies and modal shapes in the top 15 orders were obtained, distribution regularities of stress and deformation of each part of the screen box under the static load were revealed, providing the ...
Finite Element Analysis While screen design has evolved and improved from many years of operational experience and industry know-how, Weir Minerals has taken these improvements a step further. In 1992 we introduced the Finite Element Analysis FEA method of design to our development methodology. Our FEA capabilities have assisted in optimising

Reviews. The Introduction to Finite Element Vibration Analysis by Professor Maurice Petyt is a well-written and detailed account of methods and equations leading to the solution of problems involving finite element analysis. This is an excellent reference and textbook, which is ideal for both students and users of finite element techniques..
Vibration analyses using finite element methods have become standard practice during various stages of vessel design since potential issues can be identified and remedied before construction begins. Finite element analysis is an invaluable tool which can be used to avoid serious vibration problems and save on costly remediation that might be ...
There are many books on finite element methods but few give more than a brief description of their application to structural vibration analysis. This book presents an introduction to the mathematical basis of finite element analysis as applied to vibrating systems. Finite element analysis is a technique that is very important in modeling the ...
vibrating screen do forced vibration when it is under high-intensity loads. It is prone to fatigue failure. The key components of the vibrating screen are screen box, because of its complex structure and shape the traditional design methods cannot calculate its stress. 1.1 Construction of the finite element

Dynamic models of vibrating screens can simulate motion of the vibrating screen structure and show good agreement with experimental measurements and finite element method FEM results . The linear model proposed by He and Liu 28 considers three degrees of freedom.
Finite Element Analysis of Rods Consider an elastic uniform rod of total length L R as shown in Fig.1. Upon applying the FE technique, the rod is discretzed into a finite number of elements. As the rod under investigation is uniform, it is assumed that all elements used to mesh the complete rod are identical.
Vibrating screens are often used in the mining industry to separate mineral particles by size. In many designs, spring arrays are used to provide the system with the necessary stiffness for screens to vibrate in a controlled manner. Naturally, these springs are subjected to varying loading cycles, which can cause their premature fatigue failure. This behavior has been studied by means of finite element analysis
