RESEARCH ON THE FAULT SIMULATION AND PREDICTION OF THE SELF-PROPELLED GUN PERFORMANCE BASED ON ADAMS EXPERIMENTAL SIMULATION PLATFORM

Fault simulation is one of the key means to ensure the reliability and safety of the weapon systems. This paper discusses the advantages and disadvantages of ADAMS (Automatic Dynamic Analysis Mechanical System) simulation platform and the expert system based on the analysis of the actuality and development of fault simulation instruments. Considering the particularity of the causes leading to the faults of the weapon, the present paper has put forward for the first time a model with the corresponding techniques designed for the simulation. The modeling process has been designed for the simulation with the quantitative changes of the system running conditions with the help of the computer data input. To present such a complex dynamic process in a simpler and clearer manner, we have established a dynamic membership formula in accordance with the changes of the working conditions, namely, the abrasion, weariness and so on, which can be shown in a variety of components and physical parameters. Based on the result predicted, the actual fault components can be brought about by using the data provided in an expertise system concerned. The simulation model resulted contains actually not only a variety of the dynamic proprieties and the performance characters of the gun tested but also the experience and decision of the experts. In addition, it also helps to analyze the actual value of the computation and process control. The paper also provides an overall structure and function frame of Self Propelled Gun Fault Simulation System (SPGFSS). It would be more meaningful to say the present simulation model may give a direct push to the arms safety and security insurance.
