Optimal Design Rules Applied To The Design Of High-Speed Mechanisms Under Deflection And Stress Constraints, Frank W. Liou, Jenny Liu
Optimal Design Rules Applied To The Design Of High-Speed Mechanisms Under Deflection And Stress Constraints, Frank W. Liou, Jenny Liu
Mechanical and Aerospace Engineering Faculty Research & Creative Works
Presented in this paper are two approaches for the design of flexible mechanisms under stress and deflection constraints. Based on the optimality conditions derived in this paper, two procedures are developed to design the minimum weight of mechanisms subject to stress and deflection limitations. The first procedure is the improvement of Thornton's design process r 17), and the second procedure is based on the interpolation technique. Several design examples are also presented to demonstrate these methods.
Behavior Of Ductile Materials Under Impulsive Loading, M. Y. Brunner
Behavior Of Ductile Materials Under Impulsive Loading, M. Y. Brunner
Tanzania Journal of Engineering and Technology (TJET)
Ductile materials under dynamic loading are known to be able to absorb energy and thereby delay or even prevent structural failure. This paper is concerned with such behaviour in the case of impulsive loads of short duration. It is shown that even when the feared, unstable, labile condition is attained, failure may not necessarily occur. This behaviour is particularly impressive for structures with large mass, because it is essentially the mass which slows down the attainment of the failure strains. If the impulsive load dies away quickly enough, the constant plastic resistance will be adequate to bring the increasing deformations …
Development Of A Spray Drought Cooling Tower, O. K. Kaunde
Development Of A Spray Drought Cooling Tower, O. K. Kaunde
Tanzania Journal of Engineering and Technology (TJET)
ABSTRACT A noval type direct contact cooling tower has been proposed in which the gas or air entering the tower is drawn by the ejector action of the sprays through which the feed water is admitted. The advantage offered by this type of tower is that it eliminates the usages of fan, thus saving the capital cost and power to drive it.
Entrainment of air by water was studied in a laboratory cooling tower and the result of the entire experiment indicate that the development of a spray drought tower is a feasible practice.
Computer-Aided Analysis And Design Of Rectangular Buried Tank Walls And Its Safety Factor Evaluation Based On Yield Line Analysis, Rakiya J. Fatoohi
Computer-Aided Analysis And Design Of Rectangular Buried Tank Walls And Its Safety Factor Evaluation Based On Yield Line Analysis, Rakiya J. Fatoohi
Civil & Environmental Engineering Theses & Dissertations
This thesis presents the results of a study that determines the true safety factor of underground square reinforced concrete tank walls.
The walls are analyzed and designed by elastic method. The amount and distribution of the reinforcement was determined by use of the alternate design method (working stress) in compliance with all ACI code requirements. The wall's ultimate moment was computed by use of yield line theory assuming non-isotropic reinforcement. The ultimate value of the earth pressure was computed and compared with the elastic analysis and design values to give the true safety factor.
The results of this study indicate …
Structural Sensitivity Analysis On A Parallel Computer, Niu Kian Teck
Structural Sensitivity Analysis On A Parallel Computer, Niu Kian Teck
Civil & Environmental Engineering Theses & Dissertations
Substructuring formulation using adjoint variable approach has been developed for design sensitivity analysis and optimization of large scale structures. In this study, the procedure for statics and sensitivity analysis are re-examined to propose a programming scheme which can be implemented either in a sequential or parallel environment. The computational times of the substructuring formulation using a single processor versus multi-processors are compared to see the effectiveness of the formulation in the concurrent computing environment.

The post-buckled performance of cross-braced single angles was experimentally determined. The results of this study will be used by the Bonneville Power Administration for the analysis of member performance in transmission towers.
Transient Flow Inverse Study Calculation Of Unsaturated Permeability Of Wood, Farid Piroozmandi
Transient Flow Inverse Study Calculation Of Unsaturated Permeability Of Wood, Farid Piroozmandi
Dissertations and Theses
One of the major processes in lumber industry is wood drying. This process consumes large amounts of energy and capital, and due to the length of time it takes, it acts as a governing factor in lumber production levels. Development of improvements in processes and equipment used in wood drying can be expedited through computer simulation of various drying procedures. These numerical simulations depend on the accuracy of numerical models representing wood transport properties, including functional dependency of liquid permeability through wood with respect to local saturation level. Data available in the literature mainly represent wood permeability properties at fully …

Stability Analysis Of Closed Surge Tanks By Phase-Plane Method, Mostafa A. Sabbah
Stability Analysis Of Closed Surge Tanks By Phase-Plane Method, Mostafa A. Sabbah
Civil & Environmental Engineering Theses & Dissertations
The governing equations describing water level oscillations in a closed surge tank with compressed air at the top of the tank are a set of nonlinear ordinary differential equations if the hydraulic system is analyzed as a lumped system. These oscillations are stable or unstable depending on the parameters of the plant and the type and magnitude of the disturbance.
The present available stability criterion has been developed by linearizing the governing equations and is, therefore, valid only for small disturbances.
In the research reported herein, the governing equations are normalized to reduce the number of parameters from nine to …
Experimental Determination Of Post-Buckling Performance Of Steel Angles, Rupasiri Purasinghe
Experimental Determination Of Post-Buckling Performance Of Steel Angles, Rupasiri Purasinghe
Dissertations and Theses
An experimental testing program was conducted to determine the compression member performance in post-buckling region. These results are compared with an analytical computer program developed by Portland State University under Bonneville Power Administration Contract 79-80BP 24005. The paper presents the sensitivity of the performance of single angle compression members to various parameters such as length to radius of gyration ratio, eccentricity, end conditions and yield stress. The effect of local buckling on long member performance is also documented.

A Solar Energy System For Space Heating And Space Cooling, Thomas J. Mcnamara
A Solar Energy System For Space Heating And Space Cooling, Thomas J. Mcnamara
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
To help reduce natural gas and electrical operating costs, a retrofit space heating and space cooling solar energy system is integrated into the existing conventional heating and air handling systems serving the exhibit spaces. This installation would not only provide substantial energy cost savings to the Museum, but it would also provide a means of showing and explaining the operation of an actual working solar energy system to the large number of daily visitors to the Museum. This report explains the design, operation and performance of this solar energy system.
