To improve ultrasonic suspension bearing performance， a design method for structural optimization of radial inclusive ultrasonic suspension bearings is proposed. A mathematical model of natural frequency and radial deflection of bearing shell structure was established based on flat shell and elasticity theory. The three parameters shell structure， length， and radius and wall thickness， were taken as the design variables， and the natural frequency and radial deflection of shell structure were taken as the functional optimization objective. A multi-objective genetic algorithm was used to solve this problem. From the Pareto solution set obtained， a set of solutions most in line with design requirements （40 mm in length， 10 mm in radius， and 2 mm in wall thickness） were selected as the optimization results. To verify the efficacy of the optimization method in this paper， three groups of bearings were made for comparison testing. Experimental results show that the optimized bearing structure takes ultrasonic suspension bearing natural frequency and radial deflection performance requirements into account， and can produce a large radial suspension force. This research method and the results of this study can provide important and significance guidance for the design and manufacture of new ultrasonic suspension bearings.
