Numerical analysis of random vibration fatigue for a typical airborne equipment
نویسندگان
چکیده
In this paper, the fuel pump impeller was selected as a typical airborne equipment for investigation of random vibration fatigue. First, based on platform ANSYS WORKBENCH, reasonable calculation FSI carried out. Then, stress transferred to modal analysis, and prestress-structure extracted. Through response obtained. The Palmgren Miner rule Dirlik fatigue method used calculate life, result consistent with practice. work in paper provided about how obtain life prestress-structure, which critical references aviation technologists.

Analyzing Random Vibration Fatigue
Determining the fatigue life of parts under periodic, sinusoidal vibration is a fairly straightforward process in which damage content is calculated by multiplying the stress amplitude of each cycle from harmonic analysis with the number of cycles that the parts experience in the field. The computation is relatively simple because the absolute value of the vibration is highly predictable at any...
متن کاملGeneric Vibration Criteria for Vibration-Sensitive Equipment
The vibration criterion (VC) curves, commonly used in the design of facilities which house vibration-sensitive instruments and tools, were developed by the author and his colleagues, in the early 80’s, published by SPIE in 1991 and by IEST in 1993. Each of the criterion curves A through E is associated with a “line width” or “detail size” which was an attempt by the authors to describe the capa...

Random Vibration Test for Brake Shield and Fatigue life Estimation
Structures and mechanical components are frequently subjected to the oscillating loads which are random in nature. Random vibration theory has been introduced for more than three decades to deal with all kinds of random vibration behavior. Since fatigue is one of the primary causes of component failure, fatigue life prediction has become a most important issue in almost any random vibration pro...
متن کاملVibration budget for observatory equipment
Vibration from equipment mounted on the telescope and in summit support buildings has been a source of performance degradation at existing astronomical observatories, particularly for adaptive optics performance. Rather than relying only on best practices to minimize vibration, we present here a vibration budget that specifies allowable force levels from each source of vibration in the observat...
