Abstract EN
The deformation of riveting machine caused by riveting force during rivet formed makes the riveting tool out of positioning, which leads to gapping underneath the rivet manufactured head and insufficient rivet drive head.
This paper proposes a hybrid position/force riveting control method for the dual-machine drilling and riveting system to eliminate the negative effects of machine deformation.
The cooperative work of two-side machine tool is realized by a hybrid position/force control strategy, which compensates for the force-induced deformation error without an accurate stiffness model of the riveting system.
The position of pressing foot relative to the machine which represents the deformation of skin-side machine is obtained for the compensation to the displacement of skin-side actuator.
Simultaneously, the advanced force control is adopted for the stringer-side actuator.
The dynamics model of the stringer-side actuator in consideration of the machine deformation is established and identified.
The disturbance observer (DOB) and feedforward controller are introduced as the model-based control algorithm to achieve the high-performance force control.
Also, contrast experiments are conducted to validate the effectiveness of the proposed riveting control method.
The results show that the rivet manufactured head can be seated in the countersink during the forming process and the gapping under the head is eliminated.
The driven head height tolerance of ±0.1 mm is achieved by accurate force control.
