Objective To design a shock response spectrum（ SRS） test fixture on shaker for improving the shaker＇s test ability. Methods The technical contradiction model of the problem was constructed based on TRIZ matrix and dynamic simulation was combined with the tests to design a SRS fixture. Results Test results showed that the shaker＇s test ability was markedly improved with the designed fixture. Conclusion A controllable and lower cost SRS test method is offered in the lab and the TRIZ theory is proved to be effective for engineering.
