The Stability

The natural vibration frequency and forced vibration amplitude of the spring decides the stability of the whole of the spring system. Take the monolayer wave spring as the research object, do dynamics analysis for the three different kinds of wave spring with the same structure parameters. Obtain the natural vibration frequencies of the three kinds of spring through modal analysis, the result shows that the natural vibration frequency of the integral type wave spring is the highest, then is the wave spring with opening, the natural vibration frequency of the wave spring with lapping is the lowest. Do the harmonic response analysis for the springs based on the modal analysis result, the result shows that the main vibration direction of the wave spring is the symmetry axis direction of the spring, all the three kinds of the spring is much easier resonate in this direction. Through the above provides certain theoretical guidance for the design of the wave spring

Dynamic Characteristics Analysis

The principle of the magnetic levitation cylindrical linear motion guide and the theory of vibration analysis were introduced. By finite element analysis software ANSYS, modal analysis for guide was made to get the natural frequencies and vibration modes, the harmonic response analysis was also made to get the displacement response by the cutting force on the basis of modal analysis, and the influence of displacement on electromagnetic force was analysised.

In the design of ultrasonic honing equipment, it is hard to accurately get the natural vibration frequency of the ultrasonic vibration with the regular computing technology, which takes great inconvenience during designing of the device and puts it into production. This paper studies the ultrasonic vibration honing vertical equipment of φ150mm that is designed by the North University of China and carried on the natural vibration frequency analysis and corresponded numerical simulation, which got excellent achievement. In the paper the mathematical model is set up, which uses the MARC software to accomplish the numerical simulation and corresponds the vibration modal of the tool head of the devise, this paper also carries on the dynamic response analysis and solves the related difficult problem successfully. In the end, the proof test is done to support the theory.

Natural Oscillation Frequency

Приводится анализ частоты собственных колебаний большепролетной фермы с фланцевыми соединениями. Выполнен расчет фланцевого соединения с различными случаями исключения болтов из работы соединения. Анализ результата расчета показал, что возникновение повреждений и дефектов конструкций здания в локальных зонах, величина которых несущественно снижает общую жесткость каркаса, практически не влияет на динамические характеристики каркаса. The analysis of the natural vibration frequency of a large-span truss with flanged connections is given. The calculation of the flange connection with various cases of exclusion of bolts from the connection operation is performed. Analysis of the calculation results showed that the occurrence of damage and defects in the building structures in local areas, the value of which significantly reduces the overall rigidity of the frame, practically does not affect the dynamic characteristics of the frame.
