Vulnerability Analysis And Calculation On Fragment To Tank Diesel Engine

The quantitative calculation of vulnerability fragments hit tanks of diesel engine is mainly divided into three aspects: the establishment of diesel engine vulnerability analysis model,calculation of a single fragment hit diesel engine killing calculation of the kill probability and vulnerable area fragments repeatedly hit diesel engine under the probability and vulnerable area.This paper made a research on the above research,the calculation method of diesel engine vulnerability to scanning plane shooting method as the core fragment blow for tank diesel engine,and the corresponding calculation program is compiled.According to the calculation results,the measures to reduce the diesel engine's fragility are put forward.The second to the five chapter is the main content of this article.In the second chapter,a diesel engine vulnerability model is established.Through the analysis of diesel engine fault tree analysis,the key components of diesel engine are established,and the diesel engine's killing tree under given fragment attack is established to determine the fatal components of diesel engine.The diesel engine is divided into several functional areas and the diesel engine damage grade is established.Simplify the diesel engine and establish a three-dimensional model,output the corresponding part number and node coordinate information.In the third chapter,the program of plane shooting scanning is programmed by using MATLAB.The kill probability and vulnerable area of diesel engine parts under single fragment attack are calculated.The fourth chapter defines diesel standard attack direction;the killing probability calculation program written orders to hit diesel engine under the standard attack direction,destruction probability and vulnerable diesel engine in the direction of the calculation of the standard attack.Analysis of the vulnerability of the diesel engine in the fifth chapter fragment repeatedly hit by tree method,write the kill probability of the diesel engine in the fragment program under repeated blows,and calculated in the diesel engine above the corresponding blow when subjected to repeated killing probability.The research results have important reference value and guiding significance for battlefield command,tank diesel survivability enhancement / vulnerability reduction,design and optimization,warhead combat effectiveness,etc.
