A C++ program is developed for composing the stiffness matrix of the temperature field, saving it in changing bandwidth method and calculating the linear algebraic function group through using the Gauss eliminating method. A module for drawing the color fringe of tire temperature field is created, which makes the result more visual. Taking the 9.00-20 cross-ply tire on CA1092 as an example, the finite element numerical simulation analysis of automobile tire 2-D steady temperature field is completed. Through comparing the result with the analysis data by ANSYS, this software is proved to be capable of the modeling, calculating and post-processing of FEA of automobile tire 2-D steady temperature field.

Firstly, the thesis introduced the development of VOD, the background and meaning of the program, then the author introduced the associated technology, mainly including the feature of multimedia, video compression technology and the protocols SCTP and RTP. Considering the ambulant of host , fluctuation of bandwidth,high error rate data in wireless networks ,the author proposed some QoS strategy in the wireless networks such as RTP/SCTP protocol stack , connection control of the server, two buffers in the client end point.,TFC congestion control algorithms ,etc. Based these strategies, the team members gives the software and hardware solution of the wireless video-on-demand system and gives the main modules design of the software system. The system adopted the C/S structure including two parts: server and client ,using the Mpeg-2 which is apporiate for networks as the supported format. The thesis emphatically researches on the video-serving module of the server and the sink module, player module of client.
