Notify your administrator of your interest. Mechanical Vibration and Shock Analysis, Volume 3 - Random Vibration 3rd Edition Details The vast majority of vibrations encountered in the real environment are random in nature.
Such vibrations are intrinsically complicated and this volume describes the process that enables us to simplify the required analysis, along with the analysis of the signal in the frequency domain. The power spectrum density is also defined, together with the requisite precautions to be taken in its calculations as well as the processes windowing, overlapping necessary to obtain improved results.
An additional complementary method - the analysis of statistical properties of the time signal - is also described. Related Articles. Paper Title Pages. Abstract: A passenger station in Hongkong with a special structure whose roof is supported by nine mega columns which are linked in the middle by joints. The conventional design standard are inapplicable and alternatively for this structure, the design of the supporting columns of the passenger stations was verified by both finite element analysis and manual calculations. The results are consistent with each other. Abstract: This paper points out the practical significance of the finite element analysis of kinetics on the structure of simultaneous effect of static load and sinusoidal load, and according to the theory of finite element method ,the principles and methods of solving problem were studied, and then in the general finite element software of ANSYS ,through a concrete example, the solving process of the problem was achieved.
This method could be used to the dynamic analysis on the structures of simultaneous effect of many different frequency sinusoidal load. The applied scope of finite element method must be extended by using this method. The stress distribute drafts of the gear is obtained so that it is convenient to check the bending strength of the root of the gear and the fatigue contact strength of the face of the gear. The result is similar to the real situation. The whole process of model construction, analysis shows that ANSYS software is a reliable and effective tool which could provide theoretical basis to the gear teeth strength designation.
Abstract: Took a type of fully-automatic hydraulic press beam as the object of study, established its 3D model by CAD Pro-E, and then import them into finite element analysis to analyze the value and distribution of the stress and strain, finally studied the fatigue life of the beam according to the finite element static analysis result and the S-N curve of the beam material by using ANSYS fatigue analysis module.
The methods and conclusions have practical significance to understand the hydraulic press structure and improve on the structure design and life assessment of the fully-automatic hydraulic press beam.
