摘　　要：目前回弹仪只能采用部件法检查并结合极限回弹值率定来推其是否合格,无法对实际使用范围的回弹值进行溯源;根据弹性碰撞及动能吸收原理,将不同质量钢砧置于弹性垫上,用回弹仪对其弹击,可以获得稳定的低回弹值,从而实现测量范围内回弹值的溯源;有效解决解决回弹仪回弹值溯源难题。At present, the rebound instrument can only use the component method to check and combine the limit reboundrate to determine whether it is qualified or not, and can not trace the return value of the actual use range; According to the principle ofelastic collision and dynamic energy absorption, the anvil of different masses is placed on the elastic pad, anda stable low return valuecan be obtained by hitting it with a rebound instrument, so that the source of the return value within the measurement range can beachieved. Effectively solve the problem of tracing the return value of the rebound instrument.
