The Moment

The paper deals with both the theoretical aspects and the practical experience with temporary steel bridge dynamic analysis. Since the moment people built the first bridge it became necessary to replace it in case of natural disasters like wind storms, floods, earthquakes, tsunami or wars and terrorist attacks. As a construction of a stable bridge lasts for a long time, the solution is a temporary bridge - a steel bridge structure designed especially for fast and repeated assembly and disassembly. The paper presents experimental analysis of steel bridge dynamic properties. The experimentally measured results are compared to theoretically calculated ones. Besides frequency analysis of supporting structure, the noise of the bridge during car passes is also measured and analyzed as nowadays traffic noise becomes a more and more important aspect, especially in case of temporary bridges. The bridge measurements are repeated for a clear bridge and for a bridge with anti-vibration mats attached to compare the arrangement results in decrease of traffic noise and the dynamic load of the bridge.

The paper deals with an experimental analysis of a technological head tilt angle impact to vibration generation. The search of the technological head tilt influence is performed for three technological head shift speeds and for three abrasive water medium pressure values. From graphic records showing relation of vibration acceleration amplitude to its frequency, a group of 9 comparative frequency envelope graphs for two tilt angles and three technological medium analyzed pressures for each of three speeds of the head shift is created. On the base of the frequency envelope comparative graphs a discussion and formulated conclusion are stated. The paper presents a thematically integrated part of the thesis and complements recent knowledge on water jet technology manufacturing system working condition diagnosis.
