The paper establishes the dynamic nonlinear equation of composite tube under moving pressure, in which the tube is placed on the fixed and elastic foundation. The experimental model to determine the dynamic response of composite tube on fixed and elastic foundation under inside moving load is built. Experimental results allow to expand the direction of numerical simulation to select reasonable parameters for cylindrical structures. This experimental result is the basis for verifying the relevance of the theoretical and experimental methods. Experimental results and theoretical calculations are in a good agreement, the errors are acceptable with the conditions and existing laboratory equipment.    Keywords: composite tube; moving load; experimental; fixed foundation; elastic foundation.
