In this paper, at first research of relation between correlation-interval and estimation accuracy is carried out, and the optimal correlation-interval is proved to be existent that is adaptive to signal-to-noise ratio and velocity varieties. Then some special characteristics of the optimal correlation-interval are explored. Based on them an iterative correlation-interval optimized (CIO) algorithm is proposed. It optimizes the correlation- interval and calculates the Doppler spread by increasing the resolution on time-domain iteratively. Simulation results show that contrasted to conventional schemes the proposed approach is less sensitive to signal-to-noise ratio and velocity varieties, and can improves the performance dramatically in low signal-to-noise ratio environment in which the conventional schemes has a poor performance. It achieves the high accurate estimation of Doppler spread directly.

Traditional boundary element methods with a full matrix equation for acoustic problems, have been met by a challenge in large-scale scientific computation and numerical simulation in engineering. In this paper, the new wavelet approaches have been presented for solving acoustic radiation and scattering, and structural-acoustic coupling. The boundary quantities are expanded in terms of a basis of the orthogonal wavelets on the interval, and a wavelet spectral formulation for solving acoustic problems is derived. Then coupled wavelet spectral and finite element method is formulated for solving sound-structure interaction. The advantages of the new approaches include a highly sparse matrix system which can be solved rapidly by sparse solvers and accurate modeling of curve surface. In the new technique, the iterative technique of frequencies is established for evaluating frequency-response functions through expanding the integral kernel in Taylor series in integral equation. The new technique was employed to investigate the underwater acoustic radiation from a complicate structure which is composed of shells, stiffening ribs and plates. The comparisons of the results from the new technique with analytic solution show that it has high computational efficiency and good accuracy.
At the end of the paper, the prospects of the application of wavelet analysis to numerical computation in acoustic engineering are discussed.

Special programs and general programs applied to suspension bridge analysis have their limitations. This paper focuses on ANSYS-secondary-development and makes it possible to analyze suspension bridges both with accuracy of special programs and convenience of general programs. This paper is dedicated to saddle simulation,incremental launching realization and how to obtain unstressed length of main cable and slings and how to keep it unchanged. In the end, the method is verified through finite element model in Runyang Yangtze River Bridge.
