振动测试系统在动力学参数测试中的应用.

This paper presents a method for testing the dynamic parameters of the contact system. The method is based on the single-degree-of-freedom forced non-resonance method, the vibration test system is used for harmonic excitation, the acceleration sensor is used to collect the excitation signal and the response signal, and the correlation analysis method is used to process the signal, so that the equivalent contact stiffness of the two objects can be obtained, as well a s the equivalent contact damping coefficient. In order to illustrate the application of this method in the analysis of actual mechanical system dynamics, two application cases are given. They are to test dynamic parameters of the 0-ring rubber flexible support system and the "spindle-package-roller" system. This method provides a new way for experimental testing of complex rigid-flexible coupling contact systems. [ABSTRACT FROM AUTHOR]
