为了研究LHZC6/60型振动流化床干燥机主要模态的特性,对干燥机进行简化,建立有限元模型。利用有限元分析软件ANSYS对干燥机进行了模态分析,求出干燥机的前8阶固有频率和振型图。通过分析干燥机的振型图得到振动流化床干燥机的动态特性和其结构的薄弱环节,这为该机结构的改进设计和动态分析提供了理论依据。 相似文献

The collapse and energy dissipation characteristics of metal tubes braced with tension members are considered experimentally and load bounding techniques are employed to estimate collapse loads of such tubes. The results are applied in the full scale crash testing of a vehicle impact attenuation device composed of clusters of steel tubes and subjected to high speed roadway collisions. 相似文献

Formulas for the response of an optical detector to the transmitted component of a tilted absorbing glass plate are derived in terms of the angle of incidence, the thickness of the plate, and the absorption coefficient and index of refraction of the glass. Numerical results are discussed for detectors of various sizes compared to the width of the incident beam and thickness of the plate. 相似文献

This paper describes a tunable vibration absorbing isolator. The device is based on the liquid inertia vibration eliminator, which is modified so that the frequency at which maximum isolation occurs can be changed in real time. This is achieved by using adjustable pneumatic springs. A theoretical model describing the device is derived using Lagrange's equations. The model is used to design a practical device and experimental results confirm the validity of the model. With the experimental device a roll-off of about 90 dB/decade over a 12 Hz frequency band was achieved. 相似文献
