On the basis of numerical model of speed change gears and considering the relative error of speed change system, the target function for optimization of transmission plan by means of a computer is achieved.
The numerical model of the virtual machining tool is established by using openGL technology on Visual C++ platform. The various mathematical models related to physical simulation are built by using C++ language. The geometric and physical simulations of NC turning are established in the virtual environment.
Through setting up outside database and digitized model,using the programming technology facing object and outside database to realize related design,which make the irrigation designer get the corresponding figure through setting up the parameter,or revise CAD figure and receive this amended design data of figure directly. It can really improve the design efficiency of the dike.
