Abstract This paper is concerned with Analysis of Vibration and Noise in a hydraulic networks. In the analysis it is tried to find the discrete frequencies. So, we are able to recognize the damages or to redesign the system. The most important effectiveness on the system ought to the flow in the phase of vorticity.

Base Structure

This paper describes the vibration analysis and optimization of a base structure and a beam-like attached damper sub-system that couple in vibration through distributed-contact friction damping. The objective is to tune the characteristics of the damper sub-system to maximize energy dissipation, and therefore to control vibration of the base structure. Applications of the concept to noise and vibration phenomena associated with automotive disk brake rotors are discussed. Per-cycle energy dissipation is examined as a function of damper preload for two classes of sub-systems: dampers that are split rings, and dampers that are continuous rings. End-effects and the manner in which energy dissipation is distributed spatially along the damper are also discussed. Of potential technological application, for a given excitation frequency, the damper sub-system’s design can be optimized to reduce vibration of the base structure.

This article focuses on various features of a finite element analysis (FEA) program designed by IDIADA, a Barcelona-based company providing design, engineering, testing, and homologation services to the automotive industry. The program has been designed as a solution to the problem of squeaks and rattles in an automobile. FEA software used by engineers from automotive testing company IDIADA detects potential automotive noise. The company uses Abaqus Unified Finite Element Analysis from Dassault Systèmes’ brand Simulia. The team delivered a paper at the Simulia Customer Conference in Barcelona in May 2011 to present the latest improvements in their methodology, applied to rattle in a car instrument panel and correlated with real-world testing. Research has shown that a standard noise-and-vibration analysis method alone can’t model, or predict, the contact that will result in a rattle. The engineers need to come up with a simulation that can accommodate both frequency for noise and vibration and contact for squeak and rattle.
