摘要

针对油气悬挂在制造或服务一段时间后,某些工作参数会发生变化,且不易直接测量的问题,提出了一种基于数学模型与遗传算法的反演方法。首先,应用描述实际气体状态的R-K方程和计算紊流阻力系数的Blasius公式建立了油气悬挂的数学模型。在悬挂基本几何参数和实验数据的基础上,以数学模型正向求解样本点输出力的均方差为目标函数,应用遗传算法优化搜索其工作参数,在达到设置误差时,反演结束。最后简要分析了该方法的正确性及稳定性。

Abstract

After a hydragas suspension has been manufactured or used for some time, several parameters may be changed and some of them may not be easily measured. A nondestructive testing method, which is based on the mathematical model and the genetic algorithm to detect the changed parameters, was presented. The R-K equation which can accurately describe the gaseous state and the Blasius equation for computing turbulent resistance coefficient were used in establishing the mathematical model of hdragas suspension. Taking the mean square deviation of sampling points of the output force as our objective function, the genetic algorithm method was used to search for the changed parameters based on the suspension’s geometry parameters and some experimental data. The correctness and stability of the new method was discussed in brief.
