Modal controlAccurate determination of mode shapes and resonant frequencies of high-speed slender robotic arms, known as flexible link manipulators, is fundamental for mechanical design, dynamic analysis, identification, and control of the manipulators. This paper presents a Finite Element (FE) modeling...
Modal functions in Indian music have been defined in two ways: according to general tonal function; and according to phrase structure. Sets of terms for each exist in traditional music theory, both originating from lists in theNāṭyaśāstra, where they are applied tojāti; hence the names...
利用振型(Mode Shapes)的正交性,我们可以将一个多自由度体系(MdofSystem)的结构,转化为以振型为坐标的若干个单自由度体系(Sdof System)进行求解,求得单自由度的地震响应后,再将振型响应组合得到结构的总的响应,因此振型(Mode Shapes)是结构动力学中非常重要的一个概念,然而又是非常抽象的一个概念。如何理解振型...

A plane truss and a simply supported plate subjected to impulsive forces, commonly used in modal analysis are studied. The resulting KL modes are compared to the analytical mode shapes. Damping and random noise effects in the procedure performance are evaluated. Two methods for indirectly obtaining...
The aim of this work was to develop a simplified fi- nite element model of this device which is capable of predicting natural frequencies and mode shapes. The finite element equations were developed using a varia- tional principle (minimum total potential energy) and generalized eigenvalues of ...
You can now use ANSYS files in Simcenter Testlab to: Qualitatively compare experimental and simulated modal analysis results Animate mode shapes in a side-by-side display Use the FE geometry to expand your mode shapes and animate your experimental modes on a denser and more realistic geometry. ...
A numerical method is developed by replacing the uniformly distributed, discrete elastic cross-tie model with an equivalent, continuously distributed, elastic cross-tie model in order to calculate the modal frequencies and mode shapes of the cable-crosstie system. The effectiveness of the proposed ...
aThe types of equations which arise from modal analysis are those seen in eigensystems. The physical interpretation of the eigenvalues and eigenvectors which come from solving the system are that they represent the frequencies and corresponding mode shapes. 出现从模式分析等式的种类是在eigensystems看见的...
