State-of-the-artMechanical networks model for the plane frame system

AbstractThis paper describes how a mechanical networks model is employed to analyze a two-dimensional frame system in mechanical and structural engineering. The theory and method of the mechanical networks model includes three main phases: (1) modeling by using a directed line graph; (2) formulation by using a Roth's diagram; (3) processing of results by interactive computer software. A two-dimensional numerical example with the complete program written in apl programming language is presented. The whole modeling process is easy to be understood and the formulation and processing of results can be carried out systematically and consistently.The main purpose of developing the mechanical networks model is that we are trying to obtain a uniform and systematic theory and method which can be employed in the design process to analyze and synthesize a great number of engineering or non-engineering systems, such as mechanical, electrical, economical systems, etc. The mechanical networks model presented in this paper has shown to be probably such a kind of ideal universal analysis method.

PaperThe planning of a straight line trajectory via interactive computer graphics

AbstractThe planning of a straight line trajectory using an interactive computer graphics simulation of robot manipulator movement is discussed. This new approach to straight line motion planning improves the “bound deviation joint paths” method developed by R.M. Taylor. The new approach has three characteristics: (1) linear interpolation in joint space; (2) unequal intervals for interpolating knot points; (3) using interactive computer graphics to assure that the maximum deviation in the whole segment is less than the pre-specified values. The structure and mathematical basis of a computer program developed for this purpose are presented.

An Efficient Inverse Kinematic Solution with a Closed Form for Five-Degree-of-Freedom Robot Manipulators with a Non-Spherical Wrist

SummaryIn this paper, the efficient approach which was developed for computing an inverse kinematic solution with a closed form has been extended from a six-degree-of-freedom to a five-degree-of-freedom robot manipulator with a none spherical wrist. The TR 4000S spray paintinq robot manipulator has been used as an example to describe the principles. The inverse kinematic computation with a closed form solution shows that it is very systematic and efficient and easily carried out.

Study on a new technological scheme for cold forging of spur gears

AbstractInsufficient corner filling is one of the main disadvantages of conventional cold closed-die forging of spur gears. To guarantee the dimension accuracy of spur gears, how to improve the filling condition is very important. Because the die shape is one of the most important factors in forming, three design schemes with different die shape are researched in this study. Firstly, finite element method is used to simulate the cold forging process of the spur gear with two-dimensional axisymmetrical model, and the strain distributions and velocity distributions are investigated through the post processor. Radial-flow-velocity distribution is an important indicator to be evaluated, and a relatively better scheme is selected. Secondly, three-dimensional simulation for the relatively better scheme is further performed considering the complicated geometric nature of gear, and the results show that the corner filling is improved and well-shaped gear is forged. Finally, a corresponding experiment is done, which is mainly utilized for supporting and validating the numerical simulation and theoretical investigation.

Mechanical Networks Model for Analysis of Elasto-Plastic Truss Systems

AbstractThe theory and method of mechanical networks model has been used to model, formulate and compute a lot of linear problems in mechanical, electrical and structural engineering. In this paper we will embark on a study of nonlinear problems and demonstrate how to solve a nonlinear system which contains elements with linear and nonlinear properties by the use of the mechanical networks model. A complete program written in the APL programming language, which is used to solve a detailed numerical example of a truss system with ten nonlinear elements, is presented. The principles and concepts proposed are easily understood, and the modelling, formulation and computation of systems can be carried out systematically and consistently.Because of our intensive and limitless desire to analysis and synthesis of a great variety of larger and more sophisticated systems, generality and complexity is a central problem in the design process of modern systems. The main aim of our present work is to develop a general, unified and systematic theory and method which can be employed in the design process to analyze and synthesize a great variety of complex systems, such as mechanical, electrical, fluid, thermal and economic systems, even biological system. The mechanical networks model developed has proved to be ideal for this type of analysis.

Self-reported health and behavioral factors are associated with metabolic syndrome in Americans aged 40 and over

Highlights•The up-to-date U.S. NHANES data confirmed risk behaviors for metabolic syndrome.•MetS and poor self-reported health are both associated with the same living habits.•The self-reported health is not a good predictor for metabolic syndrome.
