【 摘 要 】

Using the method of finite element simulation, we study the cylindrical shell filled with new lattice with vibration in the working environment. The effect of the radius of the rod and the thickness of the ring on the natural mode shape of the lattice-filled cylindrical shell is analyzed. The results show that the change of the rod radius and the ring thickness can change the natural vibration mode of the cylindrical shell, in which the rod radius has greater influence and better effect. The research results have guiding significance for the use of cylindrical shell filled with this new type of lattice.
