| Abstract: | The aeroengine main bearing test needed accurate and stable axial load to meet the performance test requirements, for this purpose，the design principle of the combined action of preloaded spring force and hydraulic force was analyzed, and a compound axial force loading apparatus with a built-in miniature force sensor was designed. Based on disturbance rejection control theory, the extended state observer was designed to observe feedback information, and combined with a nonlinear PID controller to develop a compound axial force control strategy. Finally, the compound axial force loading apparatus and its force control method were applied to the double rotor test rig of the aeroengine main bearing. The testing results show that the control accuracy of axial loading force is greatly improved. |
