摘　　要：在MCAM(蒙特卡罗粒子输运计算自动建模系统)平台下,实现了ITER窗口限制器CAD工程模型的预处理以及到蒙特卡罗计算模型的自动转换,并借助MCAM的反向转换功能和MCNP中二维几何截面绘制程序PLOT对生成的计算模型进行了验证。MCAM在ITER窗口限制器蒙特卡罗建模过程中应用结果表明对于一个具有复杂几何结构的CAD工程模型来说,MCAM提高了其蒙特卡罗计算建模的效率和准确性,可以有效地替代传统的手工建模方法,应用于实际计算分析过程中。On the basis of the pre-processing and conversion functions supplied by MCAM （Monte-Carlo Particle Transport Calculated Automatic Modeling System）, this paper performed the generation of ITER Port Limiter MC （ Monte-Carlo ） calculation model from the CAD engineering model. The result was validated by using reverse function of MCAM and MCNP PLOT 2D cross-section drawing program. The successful application of MCAM to ITER Port Limiter demonstrates that MCAM is capable of dramatically increasing the efficiency and accuracy to generate MC calculation models from CAD engineering models with complex geometry comparing with the traditional manual modeling method.
