Abstract:

To the problem of incompatible between shed supporting and Comprehensive mechanization tunneling，the functions and design alternative are put forward for the boom roadheader integrative Multifunctional construction platform. The finite element model of drilling machine is built by 3D modeling finite element analysis software. In order to know if the dynamical behavior of drilling machine has met the requirements, modal analysis and static dynamics simulation are accomplished. The results indicate that the drilling design conforms to technical targets in significant measure. The application shows that the Multifunction construction platform adapts with the roadheader . It not only can supply the step for the people who carry on the supporting work, but also have the function of automation cantilever beam. The level of mechanization and the word efficiency are increased.

Key words: coal roadway tunneling, Multifunctional construction platform, shed supporting, Simulation Analysis, dynamic characteristic
