The forward displacement analysis of parallel mechanism is attributed to find the solution of complex nonlinear equations which is a very difficult process. The more CCS kinematic chains are the more complicated the forward displacement is. Newton iterative method is an important one-dimension and multi-dimension technique which is sensitive to the initial point. Take chaotic sequences as the initial...
Axis-symmetric component is regarded as the research objective in this paper. Based on a model of phase heat transfer coefficient and a Box-Behnken experiment with five factors and three levels, the experiment results are fitted by stepwise regression method and response surface methodology. The response surface formulas are established, that fitted deformation degree, average equivalent residual...
Many questions in natural science and engineering are transformed into solving nonlinear equation. Newton iterative method is an important technique to one dimensional and multidimensional variables and iterative process exhibits sensitive dependence on initial guess point. Continuous time-delay chaotic system is the infinite dimensional system which can produce several positive Lyapunov exponents,...

The optimal design of the quenching quality using technical parameters is a problem with high dimensional multi-objective and with complicated calculations & constraints. A novel general method for high dimensional multi-objective optimal design is presented based on degree of grey incidence with hybrid discrete variables. Making response surface mathematical model, multi-objective optimization...
The displacement analysis problem of parallel robot mechanism can be finally transformed into solving nonlinear equations and the finding-process is very difficult. Moreover, the more CCS kinematic pair the more complexly to find. The mathematical programming method is adopted when the iteration diverges with the Newton and quasi-Newton methods. If chaotic sequences are considered as the initial guess...
