摘    要:为提高飞机自动化装配设备的产能分析及预测准确度,提出了一种基于动态混合威布尔分布模型的飞机自动化装配设备有效工时解算方法。根据飞机装配过程特性,建立自动化装配设备可用度的动态混合三参数威布尔模型;分析了自动化装配设备各类子系统对设备总体可用度的影响度,计算了子系统可用度的动态权重;对设备可用度的混合威布尔模型进行了参数估计,求解设备可用度后计算设备的有效工时。以某型飞机机翼壁板装配站内的自动钻铆设备为实例,验证了方法的有效性。

关 键 词:自动化装配设备  威布尔分布  可用度  有效工时

Abstract:To improve the accuracy of capacity analysis and prediction for automatic assembly equipment of aircraft,a method of calculating the effective working hours of automatic assembly equipment based on the dynamic mixed Weibull distribution model was proposed.According to the features of aircraft assembling,the dynamic mixed Weibull distribution of availability with three parameters for automatic assembly equipment was established.Subsequently,effect of all subsystems on the availability of whole equipment was analyzed.The dynamic weights of availability of subsystems were calculated.Then,availability parameters of the dynamic mixed Weibull distribution were estimated in order to solve the availability and the effective working hours of equipment.Finally,this method was tested on an automatic drilling & riveting equipment from a wing panel assembly station,and the feasibility of proposed method was justified.
Keywords:Automatic assembly equipment  Weibull distribution  Availability  Effective working hour
