author

  • M. Rezaiee-Pajand and M.R. Salari
Abstract:

This paper is about discrete sensitivity analysis. A triangular bending element with constant moment and six degrees of freedom is used. The required derivatives for sensitivity analysis are calculated explicitly. These formulations, finite element method and sequential linear programming are utilized to find shape optimization of plate bending structures. The numerical examples, which show the ability of the derivatives, are presented.

Free Vibration Analysis of a Six-degree-of-freedom Mass-spring System Suitable for Dynamic Vibration Absorbing of Space Frames

This study is concentrated on the natural frequencies and mode shapes of a simple three-member space frame coupled with a dynamic vibration absorber. The dynamic vibration absorber is modeled as a six-degree-of-freedom mass-spring system. For the first time, the free vibration of an elastic structure with a six-degree-of-freedom mass-spring system is found. Each member of the space frame has un...

Six Degree of Freedom Point Correspondences

In this paper we develop the best homogeneous matrix transformation to fit two streams of dynamic six degree of freedom (6DOF) data. In particular, we compare object position and orientation results from two 6DOF sources. A problem that arises when comparing these two data streams is that they are not necessarily in the same coordinate system. Therefore, a method to transform one coordinate sys...

Rock Slope Stability Analysis Using Discrete Element Method

Rock slope stability depends very much on the strength features of the rock and the geometrical and strength characteristics of the discontinuities (e.g., roughness, wall strength and persistence). Since a rock mass is not a continuum, its behavior is dominated by such discontinuities as faults, joints and bedding planes. Also, Rock slope instability is a major hazard for human activities and o...

Comparing two sets of corresponding six degree of freedom data

This paper is concerned with comparing two sets of corresponding six degree of freedom data that consist of both object position and object orientation. Specifically, the best rotation and translation that aligns the position and orientation of one data set to the other is constructed by solving an optimization problem. In addition, a statistical method that identifies outliers in the data sets...
