The invention discloses a multi-effect integrated kinetic energy bomb with hierarchical dissipation of impact energy. The multi-effect integrated kinetic energy bomb comprises a multi-effect bomb head assembly, a bomb body assembly and a launching assembly; and the three assemblies are mechanically inserted front and back. During extremely high-speed impact, the multi-effect bomb head assembly generates two-stage shear failure, buffer spring limit compression and first-stage impact failure, and an extremely large amount of impact energy is dissipated; during high-speed impact, the multi-effect bomb head assembly generates two-stage shear failure and compression of most of buffer springs, and a large amount of impact energy is dissipated; therefore, hierarchical dissipation of impact energy is achieved, i.e. the function of achieving high energy dissipation during short-distance high-speed impact and low energy dissipation during long-distance low-speed impact; and the kinetic energy bomb has triple non-fatal effects of kinetic energy striking, lacrimation dispersing and dyeing marking at the same time under different impact conditions, and the problems that an existing kinetic energy bomb is excessively large in short-distance power and insufficient in long-distance efficiency is fundamentally solved.
