%X The finite element motion equation of plate is deduced, the stiffness and mass matrixes with consideration of the moment of inertia are constructed and the first several natural frequencies are calculated by using the sub-space iteration method. The vibration property of generalized conforming thick/thin element ATF-PQ4a is studied. The influence of moment of inertia and shearing distortion on the natural frequencies are discussed. The results obtained by using this element agree well with those obtained by ABAQUS and the theoretical solution. It can be concluded that the element ATF-PQ4a can be used for both thick and thin plates in the dynamics range for engineering purposes.
