[Objective/Significance]The analysis of the inherent frequency characteristics of a typical T-type fixture contributes to the development of techniques for testing the inherent frequencies of structural components on the horizontal slide of a vibration table.[Method/Process]This paper studies the mechanism behind the occurrence of abnormal harmonics when a T-type fixture is used on the slide of a vibration table.Finite element simulations of the vibration table's moving coil and slide were performed to analyze the causes of the harmonics and provide guidance on how to enhance the accuracy of the inherent frequency test results of fixtures/structural components.[Results/Conclusion]Finally,it summarizes the mechanism of testing the inherent frequency characteristics of fixtures/structural components on the slides of vibration equipment and outlines prospects for future research directions.
