摘    要:针对弹用涡喷发动机风车起动过程的特点,提出一种仿真求解机制:点火前的风车过程利用径向基函数神经网络(RBFN)方法建模仿真;点火后的加速过程则采用部件匹配法建立发动机动态模型仿真求解.动态模型的非线性方程组,利用粒子群优化算法(PSO)求解,解决了传统迭代解法受初值影响不易收敛的问题.计算结果与试验数据吻合较好,证明所...

Abstract:A new simulation strategy was proposed for the start process of missile turbojet engine windmill according to its characteristic.The simulation consists of two phases: the windmill process before ignition and the acceleration process after ignition.The former is simulated using radial basis function networks(RBFN),and the latter which model is a set of nonlinear equations is solved using particle swarm optimization(PSO) algorithm.The introduction of PSO helps to solve the divergence problem of nonlinear equ...
