@@@@A transient excitation method is adopted to measure the inherent frequency of a certain domestic band saw blade system and ANSYS infinite element software is used for calculation and analysis of the correspondence between its vibration mode and exponent number and its dynamic rigidity characteristics. The result shows that the mutual coupling of the transient test and the ANSYS calculation result comply with the theoretical requirements of kinetics and finite elements. The analysis result is of reference value for promoting the optimal design of domestic band saws.
