  2. The equations of motion governing the axisymmetric elastic deformation of finite orthotropic cylindrical shells, involving the effect of transverse shear and rotational inertia, are derived. by applying the reverberation method, the displacement and the resultant forces of the shell in the phase space are expressed. then the transient waves in the finite orthotropic cylindrical shell subjected to the axisymmetric impact are obtained by using inverse laplace transforms. furthermore, the transient solutions are decomposed to the generalized ray integrals and computed numerically

    分析了計及剪切變形和轉動慣性的有限長正交異性圓柱殼中彈性瞬態波的傳播問題，採用回傳矩陣法，在相空間中給出了位移和內力的表達式。再利用laplace逆變換，得到正交異性圓柱殼受軸對稱沖擊作用時彈性瞬態波解，然後將其分解為若干廣義射線積分之和，並用數值方法求解之。
  3. The content of this thesis comes from the fujian natural science found following research task 。 it studies on a space cantilever single beam attached to a moving support 。 inertia forces which are brought by the support ' s movement ， are acceded to the equivalent initiative forces and the equivalent initiative moments 。 when we consider the relation of the forces and deformation ， we change the method of material mechanical analysis to the elastic mechanical analysis 。 further more ， we discusses the feasibility of the method which uses the multi - rigid - body discrete model to simulate the dynamic characteristic of a elastic body 。 first ， the finite segment method is adopted to establish the models of the beam 。 based on kane ' s equations ， dynamic math - model for the beam are derived 。 and by use of c - language and runge - kutta procedure ， the computer - oriented procedure can give the whole responses of the beam 。 second ， with compare to the numerical examples ， the method which uses the multi - rigid - body discrete model to simulate the dynamic characteristic of a elastic body which is under the condition of movement is verified to be feasible 。
