analysis — /euh nal euh sis/, n., pl. analyses / seez /. 1. the separating of any material or abstract entity into its constituent elements (opposed to synthesis). 2. this process as a method of studying the nature of something or of determining its… … Universalium
Noise, vibration, and harshness — (NVH), also known as noise and vibration (N V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, Harshness is a subjective… … Wikipedia
Noise, Vibration, and Harshness — Noise, Vibration, and Harshness, also known as Noise and Vibration, abbreviated to NVH and N V respectively, is the name given to the field of measuring, and modifying, the noise and vibration characteristics of vehicles, particularly cars and… … Wikipedia
Random vibration — In mechanical engineering, random vibration is motion which is non deterministic, meaning that future behavior cannot be precisely predicted. The randomness is a characteristic of the excitation or input, not the mode shapes or natural… … Wikipedia
Dynamic Vibration Absorber — In vibration analysis, a dynamic vibration absorber, or vibration neutralizer, is a tuned spring mass system which reduces or eliminates the vibration of a harmonically excited system. Rotating machines such as engines, motors, and pumps often… … Wikipedia
Floor vibration — In the design of floor systems in buildings vibrations caused by walking, dancing, mechanical equipment or other rhythmic excitation may cause an annoyance to the occupants or impede the function of sensitive equipment. A calculation procedure to … Wikipedia
modal analysis — analysis of the different vibration modes that can occur when a complex multi degree of freedom system is subject to a forced vibration input … Mechanics glossary
Modal analysis — is the study of the dynamic properties of structures under vibrational excitation. Modal analysis is the field of measuring and analysing the dynamic response of structures and or fluids when excited by an input. Examples would include measuring… … Wikipedia
Modal analysis using FEM — The goal of modal analysis in structural mechanics is to determine the natural mode shapes and frequencies of an object or structure during free vibration. It is common to use the finite element method (FEM) to perform this analysis because, like … Wikipedia
Molecular vibration — A molecular vibration occurs when atoms in a molecule are in periodic motion while the molecule as a whole has constant translational and rotational motion. The frequency of the periodic motion is known as a vibration frequency, and the typical… … Wikipedia
