摘要
基于三维非稳态温度场理论,应用大型有限元软件ANSYS,采用瞬态热分析方法对明胶靶标进行了温度场的仿真计算;并进行了实验验证。计算结果与实测结果的对比分析表明,数值仿真具有高的准确性。通过仿真计算,得到了明胶靶标不同时刻的温度场、在某一时刻沿过质点的正截面上的温度分布、以及中心点处温度随时间的变化,为创伤实验靶标的制取与应用提供了重要参考。
Based on the three-dimensional unsteady temperature field theory and the finite element software ANSYS,the transient thermal analysis method was used to simulate the temperature field of gelatin garget,and the experiment was conducted to verify the ANSYS model.The comparison of calculated results with the measured data showed that the numerical simulation had high accuracy.Through the simulations,the temperature field of gelatin target at different moments,the temperature distribution on the section through the mass center at a time and the temperature history at the center point are obtained,which supplies an important reference for preparing wound experiment target and its application.
