Abstract


Simulation technology is an important tool to understand the objective world, through the establishment of water maintenance robot simulation system (hereinafter referred to as robots), used to study the nuclear power plant a loop device detection and maintenance of key technologies, but also can be applied to the marine environment exploration of nuclear waste. Practice has proved that only ensure the correctness and reliability of the robot simulation system, in order to make the simulation system truly vitality, practicality and feasibility study and solve the key technology. Therefore, the credibility of the simulation system model has important theoretical and practical value. Summary of research at home and abroad on the basis of the the simulation credibility of the concept of system, a number of principles Simulation Systems and Simulation Credibility of the key issues. Based on the characteristics of the robot system has been established, the system is divided into six parts: the motion of the system model, the executing agency model, the forward-looking sonar model, flow model, the visual system model and the spatial and temporal consistency model, the use of simulation credibility assess the most basic method - similar theoretical method and fuzzy evaluation method, combined with the theory of comparative law, model comparison and curve method and other methods to assess the credibility of this six-part model. Designed for motion model simulation, the use of similarity theory method for solving the value of the experimental simulation credibility and the credibility of the value of the motion model weighted. Assessment of the implementing agencies, with reference to real experimental curves of the propeller, the amendment implementing agency model, given the credibility of the revised quantitative value. Forward Looking Sonar credibility assessment includes the complex obstacles assessment and forward-looking sonar detection simulation of different obstacles. In addition, according to the empirical formula of the flow simulation, the establishment of a flow model, and validation of the credibility. In the judgment of the visual system, the article refers to the fuzzy evaluation method, through a set of design factors and evaluation set, Fuzzy evaluation of the credibility of the visual system. Finally, this paper, spatial and temporal consistency of the qualitative assessment, and the FBI experiments. Through the above analysis, this paper has been part of the system simulation credibility to verify the credibility of the simulation device, at the same time laid the foundation for the validation of the model algorithm.
