Dynamic Analysis of the Sloping Bridge Using Fem

Abstract

Throughout the work rumored exaggerated levels of vibration sloping Bridge Np.2 in terms of sloping Bridge No.1. Because of the exceptional importance of hair within the bridge supplay coal to the TE approach to the current drawback seriously and meted out preliminary measurements to see the vibration state of the development of the sloping bridge. In this paper modeling the sloping bridge is performed with the package package FEMAP and NX NASTRAN. FEMAP (Finite part Modeling And Post-processing) may be a package package used for the analysis of components and structures using the finite part methodology. it's vital to say that FEMAP has outlined units, or programs running on principle while not activity units. as a result of this, you wish to watch out once coming into all sizes, so as to get additional units of research results. within the gift case, as basic units can use: metric linear unit and N, that consequently leads to a unit N/mm2 (MPa) for strain. Based on the calculations performed antecedently conferred measurements were performed on a sloping bridge a pair of REK Bitola we have a tendency to awaken the subsequent conclusion: By calculation shows that the utmost displacement within the initial zone of frequencies is zero.0224mm. Also when measuring the vibration of the system in conditions once the instrumentality is operational, measured a most displacement of zero.056 metric linear unit at a frequency of seven cycle per second. the utmost acceleration of zero,556 m/sek2 registered at a frequency of 28 Hz, that is much from the frequencies of frequent tones forms the free oscillations of the system or the primary zone of thickening of frequencies starting from one.84Hz to 12.08Hz. therefore the system will acquire resonance condition in several

forms treble, with no vital impact on the dynamic condition.
