| Outline of Final Research Achievements |
A purpose of the studies is to establish a design technology about the TMD (Tuned Mass Damper) control to take measures by ground environment vibration to occur by a construction machine.
The reduction effect of the environmental ground vibration by the TMD control was inspected by the vibration response analysis using the three-dimensional ground model and the experiment using the size of the original model. It was revealed that the vibration reduction effect of the TMD control greatly depended on the mass of TMD system, damping of TMD system, and the ratio of frequency for control and the resonance frequency of TMD system. The vibration reduction effect by the TMD control grows big so that the TMD mass is big, the damping is low, and the frequency ratio is almost 1. We will examine the power of the construction machine and the relations with the TMD control parameter.
