本文阐述用幂级数求解受迫振动问题的一个数值法。方法的特点是:(一)求解时不需要计算自然振动的各阶频率及振幅,(二)所根据的原理简单而应用范围广泛。方法适合于利用快速计算机以解决复杂的振动问题,对于达到塑性阶级的振动问题,地震作用下的结构振动问题等均为适宜。文中说明了求解“已知扰力”及“指定运动”二大类振动问题的方法,提出了简化及校核计算的步骤,并附有例题。

By taking into account of both dilatational and deviatoric deformations, the formulae of stress components in semi-infinite viscoelastk media under the action of a constant vertical concentrated force applied at the free surface arc derived. The media treated here-in is supposed to be a Kelvin-Voigt solid, a Maxwell solid or a solid which can be expressed by the four-element model, M-K, respectively.

By taking into account of both dilatational and deviatoric deformations, the formulae of stress components in semi-infinite viscoelastk media under the action of a constant vertical concentrated force applied at the free surface arc derived. The media treated here-in is supposed to be a Kelvin-Voigt solid, a Maxwell solid or a solid which can be expressed by the four-element model, M-K, respectively. In connection with the formulae of deformations, only the vertical displacements of the free surface are given. Besides, the expressions for lateral stresses, in the media, due to uniformly distributed vertical stresses on the free surface, are also obtained. Finally, a numerical example for illustrating the differences between the several models is worked out.

According to the principles of kinematics of rigid bodies and the engagement of involute gear, this paper is offered to analyze the location of the cutter back-off interference which may occur between the gear cutter and the work- piece in the process of cutting. Starting from more complicated geometric relations, we have worked out a group of formulae for calculating the amount of the cutter back-off without interference. These formulae show the relations between the parameters involved, thus affording a basis for analyzing their influence on each other and providing the theoretical basis for machine design, At the end of this paper, a numerical example is given to illustrate the computing method of the amount of cutter back-off.
