In order to reduce the impact of vibration caused by equipment running when precision leveling is carried on industrial plants equipment,this paper studied a kind of precision leveling shock absorber.The shock absorber is composed of suspension material and counter-weight block,the shock absorption effect is tested by the suspension materials and counterweights with different parameters,after that,precision leveling is carried out to evaluate its precision.All these tests concluded that choose the length of suspension spring is approximately 70cm,to-tal elastic coefficient is approximately 0.50,the mass of counterweight block is 5～7kg can make the vibration attenuation rate reach more than 80％,the shock-absorbing effect is obvious,measuring instrument can work normally and the accuracy of the corresponding leveling line is fine,which meets codes of practice.
