General Problems and Countermeasures in Experiments with Multi-route Harmonic Loading

Test technology by multi-route harmonic loading used in structural intensity test has drawn extensive attention today. This paper presents simply the test facility and system of multi-route harmonic loading. It has stressed on countermeasures for oil system pollution, system oscillation, servo actuator selection, control parameter setting and safety matters that happen during a test. Associated problems that affect the test of multi-route harmonic loading have also been analyzed. Using these countermeasures, it will solve effectively problems that occur during the test with multi-route harmonic loading.
