This paper proposed a set of measurement system based on the method of stick vibration mode and LabVIEW virtual instrument technology, which is used for measuring the young's modulus of loudspeaker spider. The inherent frequency and young's modulus of a cotton spider are measured by this system. After the young’s modulus is obtained, modal analysis is conducted on the sample by using finite element simulation method. The measured results and the simulation results are compared. The difference between two results is 0.4% which verify the correctness of the system.
