Virtual Prototype Design And Simulation Of The Rocket Launcher System Based On WIDSS

This paper is an important part of the pre-studied national defense task in the Tenth Five Year Plan about the study on improving existing rocket launcher to the launcher that using canister. This paper presents the whole procession of the comprehensive evaluation for the possible projects by using the Weapon Intelligent Decision Support System (WIDSS). And the dynamic analysis and results of the comprehensive evaluation are given.New developments in decision theory, artificial theory and dynamic analysis method are applied to evaluation the possible projects. The main contents in this paper are included as follows: First, has improved an format reasoning method based on multiple attribute utility model and knowledgebase theory; Second, has proposed complex utility model by improving the theory of multiple attribute utility; third, has presented a kind of Weapon Intelligent Decision Support System, based on the complex utility model and developed with COM/DCOM criterion; forth, this paper also has build the dynamic simulation model for long-rang multiple tube rocket launcher system, and the tire dynamic model has applied in the rocket launcher system dynamic simulation model; fifth, through building the rocket-launcher contact model, this paper has analyzed the dynamic forces between the rocket and launcher; finally, this paper has build the evaluation model of the project about improving existing rocket launcher to the launcher that using canister, and get the conclusion through using the WIDSS.The studies in this paper not only proposed scientific warrant to the choice of projects in this pre-studied national defense task about improving existing rocket launcher to the launcher that using canister, but also can give other studied tasks with decision supported. The dynamic model build in this paper also has important reference value for some projects. For example, the alteration to lighting the long-rang multiple tube rocket launcher system, the project about shipped rocket launcher system.
