In order to analyze the electrostatic field concerned with electrostatic proximity fuze problem using the available finite analysis software package, the technology to model the problem with a scale reduction object and boundary was presented. The boundary is determined by the maximum distance the sensor can detect. The object model is obtained by multiplying the terms in Poisson's equation with a scale reduction factor and the real value can be reconstructed with the same reverse process after software calculation....

In order to analyze the electrostatic field concerned with electrostatic proximity fuze problem using the available finite analysis software package, the technology to model the problem with a scale reduction object and boundary was presented. The boundary is determined by the maximum distance the sensor can detect. The object model is obtained by multiplying the terms in Poisson's equation with a scale reduction factor and the real value can be reconstructed with the same reverse process after software calculation. Using the finite element analysis program, the simulation value is close to the theoretical value with a little error. The boundary determination and scale reduction method is suitable to modeling the irregular electrostatic field around air targets, such as airplane, missile and so on, which is based on commonly used personal computer (PC). The technology reduces the calculation and storage cost greatly.

Based on dimensional analytic theory and non-dimensionalized thermo-mechanical coupling equations for high energy laser beam irradiation,this paper presents the similarity criterion and the scaling law for thermo-mechanical coupling effect induced by high energy laser beam under some reasonably approximation conditions.The similarity criterion and the scaling law are independent of material properties related to temperature.The finite element analysis models of full scale and scale down pressurized cylindrical shells irradiated by intense laser beam are established respectively.The numerical results show similarity between the full scale and scale down models.It is concluded that the coupling effect of the thermal-mechanics induced by intense laser beam meets similarity rules under reasonable approximations.

由量纲理论出发,分析了激光辐照热力耦合理论的无量纲化基本方程组。在一定的近似条件下,导出了激光辐照热力耦合问题的一般相似性准则,该相似准则不受与温度相关的材料特性的约束。在此基础上给出了强激光辐照充压圆柱壳体热力效应的缩比方法,并对一组实例进行了计算,得到了缩比模型与原型结果几乎完全相似的结论。理论分析与数值计算表明,激光辐照热力耦合问题在合理的近似下满足相似律。
