Optimal design criteria for isolation devices in vibration control
Vibration control and mitigation is an open issue in many engineering applications. Passive strategies was widely studied and applied in many contests, such as automotive, aerospatial, seismic and similar. One open question is how to choose opportunely devices parameters to optimize performances in vibration control. In case of isolators, whose the main scope is decoupling structural elements f...
متن کاملVibration, Mechanical Shock, and Impact
Time-varying forces and accelerations occur in daily life, and are commonly experienced, for example, in an elevator and in aircraft, railway trains, and automobiles. All of these situations involve motion of the whole body transmitted through a seat, or from the floor in the case of a standing person, where the human response is commonly related to the relative motion of body parts, organs, an...
متن کاملComputer Shock and Vibration Concerns
INTRODUCTION Digital microcomputers are ubiquitous. Computers inside the space shuttle control its descent from orbit until it slows to Mach 1, the speed of sound. At this time, the pilots gradually take over control and prepare for landing. Computers inside satellites provide a myriad of functions. For example, a satellite computer might record sensor data for later transmission to Earth groun...
متن کاملFault-Detection and Isolation Algorithms for Health Monitoring of Electronics Subjected to Shock and Vibration
Failures in electronics subjected to shock and vibration are typically diagnosed using the built-in self test (BIST) or using continuity monitoring of daisy-chained packages. The BIST which is extensively used for diagnostics or identification of failure, is focused on reactive failure detection and provides limited insight into reliability and residual life. In this paper, a new technique has ...
متن کاملOPTIMAL HYBRID BASE ISOLATION AND MR DAMPER
In this paper, optimal design of hybrid low damping base isolation and magnetorheological (MR) damper has been studied. Optimal hybrid base isolation system has been designed to minimize the maximum base drift of low damping base isolation system where for solving the optimization problem, genetic algorithm (GA) has been used. In design procedure the maximum acceleration of the structure has ...
