Numerical simulations were carried out to study the effects of flow and structural parameters on structural deformation. The curves were obtained to show the structural stress and deformation varying with the flow and structural parameters. Meanwhile, the influence degree of these parameters was investigated by range analysis, and a fitting formula of the parameters and the maximum structural deformation in this model was obtained and thus the most influential parameter on structure safety was found. Results show that there is a great difference in their effect on the structural deformation for these flow and structural parameters. The influence degree of parameters is in a decreasing order for the pipe length, fluid velocity, pipe thickness, fluid density, pipe diameter, elastic modulus, Poisson ratio and fluid viscosity, among which the first four parameters play the major role. Besides, a proper parameter selection based on the influence degree shown in the fitting formula can provide an effective control of the structural deformation.

R. china Gao Renxiang, Zhang Shiying & liu bao Forecasting Practice from Box Cox T Institute of Applied Mathematics Academia Sinica Beijing 100080 P. R. China school of management Tianjin University 300072 P. R. China

In this paper, forecasting analysis to Box Cox transformation models with a practical example is considered. Based on chosen generalized functional form, variables influencing passenger are selected by statistic mechanism, not just by subjective judgment or dependent on certain specified model, and forecasting models are constructed. Comparing with typical linear regression forecasting models, nonlinear forecasting models are more effective and precise. Based on collecting data and final forecasting models, forecasting results are obtained and forecasting errors are analyzed. Finally, some helpful conclusions can be drawn from this study.
