Evaluation And Application Of Personnel Damage Effectiveness Based On Improved Damage Matrix

The most concerned targets in modern wars are usually key military targets,such as military factories,armories,and airports.Due to humanitarian considerations and pressure on international public opinion,the strike plans generally try to avoid causing collateral damage to civilians.Therefore,assessing the effectiveness of weapons’damage to personnel accurately has been an important part of combat planning.In order to solve the problem of collateral damage assessment,this paper takes personnel as the research object,and focuses on the damage effectiveness of fragmentation warheads to personnel.The simulation method is mainly used to realize the damage effectiveness evaluation of single bomb and multiple bombs.And the corresponding calculation software is programmed,which can support the assessment of incidental damage to personnel and the planning of reasonable evacuation of personnel.Firstly,based on the digital human anatomical model and the definition of human tissue damage level given by medical experts,this paper evaluates the damage caused by the spherical fragments penetrating the human body.However,evaluating the damage effect of each fragment of the fragmentation warhead will consume a lot of calculation time and lose the practical significance of damage effectiveness evaluation for combat applications.Therefore,the application of fragmentation damage criteria based on vulnerability analysis is necessary.Secondly,based on the fragmentation criterion(SK method)proposed by Sperrazza,this paper uses accurate fragmentation field simulation models and human body models to improve the calculation method of personnel incapacitation probability in the US military evaluation process,thereby obtaining a more accurate result of single-shot fragmented warhead.By changing the placement coordinates of the human body model on the plane,the incapacitation probability distribution stored in the form of a matrix is obtained,i.e.,the damage matrix.The average effective damage area(MAEF)based on the damage matrix is introduced to characterize the damage effectiveness of the weapon to personnel.What’s more,the influence of different terminal states of the weapon on the MAEF is discussed,finding that control the scope and distribution of damage could reduce collateral damage to personnel.The simulation of weapon accuracy is realized by the Monte Carlo method.After joining the randomness of the terminal attitude,the "average" damage matrix is obtained.The results show that the Carlton function with appropriate shape factors can approximate the average damage matrix better.Finally,by processing the damage matrix of the single-shot fragmentation warhead,the probability distribution of incapacitation under multi-shot strikes can be obtained,which can simulate the multi-shot joint strikes in the real battlefield with precision strikes and fire coverage,so as to avoid unnecessary collateral damage.The genetic algorithm is used to solve the optimization model of the strike plan,and the strike plan with less collateral damage is optimized under the premise of satisfying the effective on the military target,so that to provide support for developing operation planning.By sorting out the related algorithms of damage effectiveness evaluation involved in this paper,a visual interface is developed based on the MATLAB GUI platform,which can provide an auxiliary calculation tool software for evaluation implementers.
