发动机系统建模是飞行模拟器建模的重要组成部分,发动机模型的准确度直接影响了飞行模拟的逼真程度。首先研究了飞行模拟器发动机系统的建模方法,对分排气式双轴涡轮风扇发动机进行了建模,在与真实发动机特性进行比较的基础上对模型进行了修正,在飞行模拟器其他系统配合下进行了调试验证,得到了仿真结果。并对飞行模拟器建模所特有的故障设置和ATG试验的实现方法进行了讨论及仿真验证。 相似文献

To study the uncertain optimization problems on implementation schedule, time-cost trade-off and quality in enterprise resource planning (ERP) implementation, combined with program evaluation and review technique (PERT), some optimization models are proposed, which include the implementation schedule model, the timecost trade-off model, the quality model, and the implementation time-cost-quality synthetic optimization model. A PERT-embedded genetic algorithm (GA) based on stochastic simulation technique is introduced to the optimization models solution. Finally, an example is presented to show that the models and algorithm are reasonable and effective, which can offer a reliable quantitative decision method for ERP implementation. 相似文献
