In this study, the authors conducted weight dropping impact tests of shock absorbers composed of rubber and steel pipes with various loading speed in order to investigate the rate dependency accurately. The experimental results showed that the dynamic effect on the load- displacement relationships of the absorbers are mainly caused by rate dependent characteristics of rubber material. By using the results, we proposed a method to evaluate dynamic load-displacement relationships by means of static load-displacement characteristics and confirmed the validity of the method through comparison with experimental results.
