The first few batches of cassava harvester embedded depth is not deep enough or too deep, the rate of pick up is not efficient and not efficient cassava into the soil of time differences, and for different levels of the above limitations, this paper through simulation analysis and trajectory analysis of cassava harvester to identify the performance of the structural parameters of the above. Using...
To strengthen the parts universality of a series of passenger cars and improve a passenger car ride comfort, the elastic components and the installation location of the vehicles are optimized. The optimization scheme of widening, lengthening the rear suspension leaf spring, and narrowing diameter of the front suspension torsion bar spring are analyzed, then the front and rear suspension stiffness...
The aim of this paper is modelling of optimal screw jack design using VBA Programming in AutoCAD package software. Today's demand grows need of good design and quality product with short span of time to achieve a better product. The software development in the digital world is a vital role to satisfy a number of demands, in this regard author considers CAD software to develop design of screw jack...
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...
Genetic algorithm has a primary disadvantage that computational cost increases greatly for overmuch evaluation of objective functions and their fitness. To improve efficiency of optimization by means of genetic algorithm, an improved method in aerodynamic optimization design of aerofoil is constructed by combining artificial neural network with genetic algorithm. B-Spline method was adopted to parameterize...
