The present invention discloses a design method of a metal rubber shock absorber for pipe support. According to the method, different molding densities are employed for the shock absorber blocks at different positions along a circumferential direction of a pipeline; according to a basic law that the smaller the molding density of the metal rubber, the smaller the support rigidness, and the better the shock absorption performance, a metal rubber shock absorber block having a greater molding density is used at a position under a greater pressure to improve the support rigidness, and a metal rubber shock absorber block having a small molding density is used at a position under a small pressure to improve the shock absorption performance. In this way, under the circumstances of ensuring safe serving of the entire shock absorber, a more reasonable shock absorption effect is achieved. According to the present invention, a plurality of rectangular-approximate shock absorber blocks having different densities are employed and are embedded between a plurality of limiting plates in the pipe. The internally-interconnected spatial mesh structure of the shock absorber block ensures good elasticity and damping performance. The shock absorber blocks at different positions employ different densities under the pressure distribution caused by self-weights, so as to obtain a better shock absorption effect.
