Firstly, a new design method of cam profile has been developed by using finite terms of Fourier Series in the cycle of cam angle as the basic equation of cam profile, so the difficulty of base circle wave existing in the method of resonant cam design can be eliminated. On the other hand, the method proceeds from the acceleration of cam profile, which makes the acceleration not only smooth and continuous, but also easy to be controlled, and the cam profile with good performance can easily be acquired.

此方法用以凸轮包角为周期的富立叶级数有限项作为凸轮型线的基函数，可以免去谐波凸轮设计时控制基圆波动的困难；此方法又是从凸轮型线的加速度曲线入手进行设计，使型线加速度不但光滑、连续，而且形状容易控制，便于设计出动力性能优良的凸轮型线。

摘 要：本文对沈阳市富民桥主梁的施工挂篮进行创新设计，参考同类挂篮的成功设计思路的基础上，通过将前锚梁下缘设置弧形来解决索的平面转动问题，使得主桁由万能杆件拼装的挂篮应用于空间索面的斜拉桥主梁施工中。

The plasticity performance of the material can't play effectively in elastic design, and it's economy is poor. So it's inevitable to consider the plasticity development for the plate formed by ductility materials. And confirming the plastic limit bearing capacity of the plate plays an important role in the plastic design.

由于弹性设计不能有效发挥材料的塑性性能且经济性差，因此对于由延性材料形成的板的设计，考虑其塑性发展成为必然，而确定板的塑性极限承载能力对工程设计中的塑性设计有着重要的指导作用。

In this paper, design is first conducted for the bed of a CNC lathe and Pro/ENGINEER is employed for modeling, then Pro/MECHANICA is used for finite element analysis.

Anciently, most researches focused on the history or culture of furniture. And lessinvestigation has been made into studying human''s image and affective expression about form element of furniture. It is difficult to make a good design to meet the consumer''s mental feeling if it is not considered by affective expression theory in furniture design.In this research, we take modern classical furniture as a case to study their emotion image.

以往的研究中，对于家具的研究大多局限在家具的历史与文化上，或者是对家具造型设计的探讨；而较少地探讨家具造型形态元素带给人的心理意象及情感体验，更没有完整的论述家具设计情感化的理论，这使得设计师在进行家具造型设计时无法有效掌握消费者的心理及情感需求，导致设计上的盲目和限制。
