A non-iterative design method on an approximate equal velocity ratio transmission mechanism is presented. The mathematical principle is that a compound function produced by two basic functions, let its one order differential is equal to a constant at special point, and then two to three order derivatives of the compound function are all zeroes, thus two algebraic equations are got, their solutions...
The formula of distribution coefficient about outlet circulation in the radial direction was derived by the theoretical analysis of the relationship between theoretical head of axial-flow pump with circulation of impeller. The axial-flow model pump with specific speed of 700 was designed with method of variable circulation, employed distribution coefficient according to the derived formula. The hydraulic...

The model is solved by using MATLAB optimization tool. And it provides the optimal program. The result of operation indicates this method is feasibility. Optimal design method and the using of MATLAB software are...
Based on structure first approach, proposed the constraint expressions of blade which have fine structure. On this basis, established a mathematical model for blade geometry based on Structure first approach. As the objective function is non-linear expressions, based on nonlinear programming method, by using fmincon of MATLAB software, solved the objective function and got optimized airfoil blade...
The object of this study is to propose an integrated design method for machine-part grouping problem and part-assembly grouping problem in cellular manufacturing system design using mathematical programming procedure. There is a great deal of methods that have been proposed for the machine-part grouping problem in cellular manufacturing system. But few researches consider the design for machine cell...
Conventional duct design methods either fail to achieve pressure balance and ignore energy conservation in the actual running process. A feedback simulation method that contains system simulation and correction procedure is proposed. An acidity gas exhaust system in a semiconductor factory is presented in this study to understand the characteristics of the proposed method. The results demonstrate...
Recently, electric motors are required to show high efficiency/power/torque within low cost/size and noise in every application field, such as home appliance and industrial field. This paper proposed a design method that can result in motors that show low-cost and high output characteristics. An optimally designed flat type IPMSM and a V type IPMSM was design. For the design, a novel method considering...
This paper examines uncertainty in design and traditional methods of accounting for it, while developing a methodological comparison of Monte Carlo Simulation (MCS) and Epoch-Era Analysis (EEA). Particular focus is placed on the way by which MCS and EEA handle uncertainty from both endogenous sources (i.e., those arising from modeling design and performance), and from exogenous sources such as requirements...
Integrating finite elements (FEs) into the design procedure of electromagnetic devices has always been a challenge for researchers and design engineering community. This paper presents the application of a hybrid method that involves the application of a conventional design methodology commonly employed by transformer manufacturers and 2-D FEs. The optimization is carried out using a genetic algorithm...
