碩士 === 國立成功大學 === 系統及船舶機電工程學系碩博士班 === 94 === Finite Element Method and Finite Difference Method are two existing numerical structure analytical techniques. Finite Element Method has been widely applied to general structural analyses due to its systematically encoded into computer formula. DQEM is a method of structural analysis developed by C. N. Chen. However, other than systematically encoding into computer formula, it can be more effectively get the precise solution. The dissertation is based on C. N. Chen’s DQEM to analyze the problem of transformation and vibration by considering simple shear. Considering simple shear’s beam, also called Timoshenko beam, is another kind of beam different from Euler-Bernoulli’s beam. DQEM can minimize inaccuracy in computing, result in better convergence, and substantially reduce the quantity of calculating.
