The numerical control simulation technology
puter simulation concept and the application
Looked from the project angle that, the simulation was through studies one to the system model experiment to have or in the design system. Analyzes plex dynamic object, the simulation is one effective method, may reduce the risk, reduces cycle which designs and makes, and saves the investment. puter simulation is draws support from puter, the use system model conducts the experimental study to the actual system the process. But it develops rapidly along with puter technology development, holds the more and more important status in the simulation. puter simulation process may the essential factor three basic activities which through shown in Figure 1 describe:
The modelling activity is through to the actual system observation or the examination, and cannot examine the variable in the neglect secondary factor in the foundation, carries on the description with physical or mathematics method, thus obtains the actual system the simplification approximate model. Here model should have the similarity with between the actual system function and the parameter and the correspondence.
The simulation model is (simplification model) carries on certain algorithm processing to the system mathematical model, after causes it to e the appropriate form (for example es numerical integration putatio
