In stamping process, springback is always determined by process parameters, such as blank-holder force, mould parameters, material parameters, and so on. Prediction of springback and parameters is a multi-objective optimization problem. Firstly, based on the same quantity of orthogonal experimental samples, prediction accuracy and efficiency of back propagation neural network (BPNN) prediction model...
In order to get real-time and on-line biology parameters in fermentation process, a soft sensor model based on support vector regression (SVR) is provided for estimating the biology parameters. It is well known that the complexity and generalization performance of SVR model depend on a good setting of the three parameters (ε, c, γ). So an algorithm called Particle Swarm Optimization (PSO) is applied...
To forecast quickly the operation condition of loom, optimizing operation parameters of loom, and improve the production efficiency of loom. The paper studied operation prediction of loom production based on neural network. Because traditional network method had the defects of slow convergence velocity and low prediction accuracy, BP algorithm was improved by combined algorithms by the merging of...
