【摘要】 本文建立了舰船燃气轮机推进系统的数学模型,其中燃气轮机的模型是用“瞬态扭矩系数法”建立的。将Jacobian片段线性化法与Taylor展开法结合成“Jacobian-Taylor”法,并由此生成了推进系统的二次模型,同时从实时仿真目的出发对该模型进行了简化,通过分析表明这种简化方法既有利于实时性,又能保证一定的精度。最后,在一个多微机仿真系统上对某燃气轮机推进系统加速过程进行了仿真。更多还原

【Abstract】 In this paper the models of naval ship gas turbine propulsion system are established. The gas turbine is modeled by "transient torque coefficient" method. By combining Jacobian coefficient method with trauncated Taylor series method. A new simulation method-"Jacobian-Taylor" method is proposed and by which the simulation model of the propulsion system is derived. For the purpose of real time simulation, the model is further simplified and the analysis shows that the simplification is good for real time characteristics and gives accurate results. Finally, the acceleration state of a naval gas turbine propulsion system is simulated with a multiple microcomputer simulation system.更多还原
