Dynamic Response of Beam Under Moving Mass

Sethi, Mohan Charan (2012) Dynamic Response of Beam Under Moving Mass. BTech thesis.



This thesis is about the experimental study of linear dynamic response a structure (Euler- Bernoulli beam) under a moving mass.The moving mass is constant in magnitude and moves at constant velocity. The dynamic analysis of beam is done by taking two different cases. In the first case effects of inertia of the load were neglect and in second case effects of the beam inertia were also not considered. The study of the moving load is a great importance in the field of transportation. Examples of the structural elements which support the moving masses are bridges, guide ways, overhead cranes, cable ways, railway, roadways, runways, tunnels and pipelines etc.in the first phase, dynamic equation of motion with the moving load for simply supported beam is solved by analytical method and then experimental analysis is given. In the present work, effect of moving mass on both simply supported and cantilever beam for two different materials is investigated. The effect of variation of parameters on dynamic response of Euler- Bernoulli beam is studied. The beam is divided into 20 stations and the deflection of beam at mid-span is recorded while mass moves at constant velocity through different stations. The deflection at mid-span for different station is taken with the help of oscilloscope. The result obtained is plotted in the form of graphs for different velocities of mass.
