The thermal characteristics of the motorized spindle determines maching qualities and cutting capabilities, and is one of the important factors influencing the precision of the high speed NC machine tool. To improve the performance of the high speed machine tool, it is important to study the thermal characteristics of the motorized spindle. It had been studied in two ways: one is finite element analysis by Ansys software, in which the finite element analysis model was built. According to the actual working condition, the heat source and the heat transfer coefficient of every part are calculated. On this basis, the temperature field and temperature rises were gotten in Ansys software. The other way is temperature rises experiment on the motorized spindle test platform. The result was shown in the form of curve. These two ways shown the same result: the highest temperature rise appears in the area of electromotor, then followed by the rolling bearing .The result provides the necessary theory basis for optimizing the structure of the motorized spindle and establishes a basis for the research and application about the high speed spindle.

Variational theorems are presented for analyzing the vibrational response of flexible linkage mechanisms and the surrounding acoustic medium in which they are immersed. These theorems are established by generalizing Hamilton’s principle through using Lagrange multipliers to incorporate field equations and boundary conditions within the functional. The same philosophy is adopted to handle the conditions at the fluid-structural interface. When independent arbitrary variations of the system parameters are permitted, these acousto-elastodynamic theorems yield as characteristic equations the equation of motion for each member of the linkage, the acoustical wave equation, the compatibility conditions at the interface between the fluid and solid continua, and also the boundary conditions. These variational statements provide the foundations for several different classes of finite element analysis.

Now, ultrasonic cleaning has been widely used in industry, however its applications in our lives are very few. It is theoretically possible that ultrasonic cleaning could be applied in civil. The author studies a kind of portable ultrasonic cleaning machine which is suitable for various fields. In consideration of the portable ultrasonic cleaning machine characteristics such as small, convenient, high frequency and high intensity focus, the author presents a model of compound acoustic horn which is composed of a conic horn of varying section and a horn of uniform section. Because this compound acoustic horn which has complicated shape is not traditional horn, and it is difficult to analyze it with traditional method. This situation is able to influence on the design of the acoustic horn, especially the confirmation of the vibration node, even the whole system matching. So in this paper the finite-element method (FEM) is used to analyze the dynamic performance of the compound acoustic horn. By the finite-element analysis, the natural frequency and the natural vibration mode of the compound acoustic horn are ascertained, furthermore, from the graph results we can find the stress and the displacement in the end of the acoustic horn are the biggest, but the displacement in the Flange is about zero. So the reliability performance and the reasonable design of the compound acoustic horn are proved in theory. In addition, the tests indicate the result of the finite-element analysis tallies with that of actual use after processing the compound acoustic horn.
