针对某型滑翔航弹研制中半实物仿真实验的实时性需求，基于工业控制计算机 Win-dows 操作系统和 PCI 定时板卡，采用调用外部时钟、内存动态分配和多线程技术，设计并实现了最小仿真步长为1 ms的半实物实时仿真软件。以滑翔航弹弹道初始条件为输入信息，对软件进行了测试，结果表明：该软件的单步事务处理实际耗时严格小于1 ms，均值为0．53 ms，满足滑翔航弹半实物实时仿真的需要。

A hardware-in-the-loop simulation(HILS) software based on Windows system of industrial computers and PCI timing board card was developed for simulation experiments of a gliding missile.The software adopts external clock invoking,dynamic memory assigning and multithread technology,and achieves the minimum simulation step size of 1 ms.In addi-tion,the software was tested with the initial trajectory conditions as the input parameters. The test results show that the time-consumption of a single transaction process in the soft-ware costs no more than 1 ms,with a mean value of 0.53 ms.
