摘要
为利用起落架位置参数计算收放机构运动副间隙,基于连续接触模型,建立了含收放机构运动副间隙的起落架位置计算模型。针对计算模型中,理想状态下的起落架位置参数未知而无法求解的问题,提出了以理想状态下的起落架位置参数为优化变量,以收放机构运动副间隙的两组计算值之差最小为优化目标建立多目标优化数学模型,求出其最优解并作为已知条件,计算收放机构运动副间隙的方法。计算实例表明,起落架收放机构运动副间隙计算方法可行有效。
To calculate the joint clearance of retracting mechanism by using the position parameters of landing gear, the model for position calculation of landing gear with joint clearance is established based on continuous contact model. To solve the problem the position parameters of landing gear on ideal status, the optimized variables are adopted and then a multi-objective optimal model is established by performing the minimum differences of two groups of calculation data of the joint clearance of retracting mechanism as the optimization goal, from the above- mentioned model the optimal value of the position parameters of landing gear on ideal status are calculated, so as to solve the calculating problem in the joint clearance of retracting mechanism. The calculation example shows that the method for calculating the joint clearance of landing gear retracting mechanism is feasible and effective.
