Analysis on inherent frequency of main blades of precision panel saw
CONCLUSIONS Through adopting elastic mechanics theory, using method of requesting free vibration differential equation of veneer, the article works out the inherent frequency calculating formula of main blade, by this method, the theoretical calculating and practical test of inherent frequency of main blade to be similar, while the error is within 3％ or so.In practical engineering structure, the mechanics problems maybe difficult with complex force loaded,therefore, calculate the solution with classic elastic mechanics is very few, and its difficult to get solution by analytic method, only can be done by numerical method.From 70s of last century,along with development and widely use of computer, it played an more and more important role of using efficient numerical method to solve engineering problem, the finite element method is an example.
