A novel cylindrical ultrasonic motor easy to be fixed is proposed in this article. There are threaded holes on the bottom of stator used for fixing, distinguishing it from other cylindrical stators. The bottom is machined as a round lug boss. Its radius is smaller than the inner radius of the stator in order not to affect the excitation of vibration mode. The finite element analysis was accomplished to verify the working principle. Based on the analysis, a prototype was fabricated and measured. The mechanical output characteristics were obtained by experiments. The maximal velocity of the proposed motor is 170 r/min at the operating frequency of 31.6 kHz.

Abstract In this paper, a new rotating standing wave ultrasonic motor with multiple driving teeth is proposed. Using the method of adding additional teeth, the correction of the B06 surface of the ultrasonic motor vibrator is expected, the design of the optimum position of the drive tooth is realized. At the same time, a method of reducing the stiffness of the rotor is proposed, and the flexibility is met, the integrated design of the rotor and the pressure device can be realized by removing the disc spring. The accuracy of the finite element analysis is verified by the vibration test of the prototype oscillator. The finite element analysis of the main structure parameters of the influence oscillator mode and natural frequency is carried out. It provides theoretical basis for the design and machining of vibration.

Based on the structure and working principle of our giant magnetostrictive actuator (GMA), the properties of the driving magnetic field were researched. A 3-D nonlinear magnetic field model of the GMA was established with the finite element analysis method, and the magnetic field distribution of the GMA was obtained with the software ANSYS. Then the 3-D model helped us to find the effects about the distribution of magnetic field of the GMA from the structure. The 3-D magnetic field finite element analysis model can give us a new tool of GMA design and analysis.

The SZR straight line shaker applied in a sintering plant is used as an example. Based on the shaker's performance, the inherent mode of vibration, the natural frequency and other factors were analyzed, an improvement method was proposed. The finite element analysis is used to simulate the exciting force, and performed the vibration mode and statical analysis. This will improve its application in the production practice, with a significant effect.

The tricycle reducer is widely used in many fields such as mining, petroleum and building materials because of its characteristics of large transmission ratio, compact structure and wide application, as well as its excellent carrying capacity and low cost. In order to understand the force of three-ring reducer, the finite element analysis method should be adopted. This paper, starting with the structure and working principle, carries out the multi-tooth meshing effect and the whole machine statics analysis, aiming to provide a reference for the optimization and perfection of the products.

Abstract The finite element method, which is a numerical discretization technique for obtaining approximate solutions to complex physical problems, is accepted in many industries as the primary tool for structural analysis. Computer graphics is an essential ingredient of the finite element analysis process. The use of interactive graphics techniques for analysis of tires is discussed in this presentation. The features and capabilities of the program used for pre- and post-processing for finite element analysis at GenCorp are included.

Abstract The effects of variations in stiffness and geometry on the nonuniformity of tires are investigated by using the finite element analysis. In order to evaluate tire uniformity, a three-dimensional finite element model of the tire with imperfections is developed. This paper considers how imperfections, such as variations in stiffness or geometry and run-out, contribute to detrimental effects on tire nonuniformity. It is found that the radial force variation of a tire with imperfections depends strongly on the geometrical variations of the tire.

The purpose of this study was to determinate , using the Finite Element Analysis Method, the mechanical stress in a solid body , temporary molar restored with the self-curing GC material. The originality of our study consisted in using an accurate structural model and applying a concentrated force and a uniformly distributed pressure. Molar structure was meshed in a Solid Type 45 and the output data were obtained using the ANSYS software. The practical predictions can be made about the behavior of different restorations materials.
