【摘要】 针对非线性的机载航炮系统,提出"分段线性传递函数法"的方法,并采用该方法进行后座力识别;同时提出"传递能量"的概念,给出其明确的定义,在此基础上对非线性进行了定量的描述,并修正后座力识别结果。结果表明,该方法与使用线性近似方法解决后座力问题在工程上有大的改进。更多还原

【Abstract】 Aiming at analysis of nonlinear airborne gun system, a method of piecewise linear transfer function is provided to identify the aerogun recoil. The concept of transferred energy is introduced and clearly defined, on this basis, a quantitative description of nonlinearity is presented to correct the identification results. The results indicate that compared with the linear approximate identification, the method to solve the recoil problem is greatly improved.更多还原
