The invention relates to an anti-collapse particle type damping beam which comprises a beam shell, particles, intelligent material coating layers, a sealing layer and a vacuum pump. A cavity is reserved in one end of the beam shell, sealed through the sealing layer and filled with particle materials. The surfaces of the particle materials are coated with the intelligent material coating layers. The outer surfaces of the particles are coated with the intelligent material coating layers, so that the movement of the particles is limited, the pressure between the particles can be controlled, and structural vibration can be controlled by adjusting the applied pressure. An energy dissipation mechanism of the anti-collapse particle type damping beam is different from that of a traditional particle damper dissipating energy through particle collisions, in a low-pressure state, the particle materials are tightly coated with intelligent materials, due to the compression of the materials, the contact force between the particles starts to be increased, and a fully-filled state is achieved. The interaction of the particles can be weakened or enhanced and depends on the pressure level, energy is dissipated through friction and sliding between the particles and the particle coating layers, local deformation and the like, the strain energy of a vibration system is mainly converted into kinetic energy, the kinetic energy of the system is then dissipated through the deformation of an energy dissipation device, so that a main structure is protected, and the anti-collapse capacity of the main structure is improved.
