燕尾

Every kind of chirography formed its unique aesthetic imagery,and so called "iron-hard picture and flying characters","silkworm head and swallow tail,as square as framed","beautiful as a silver hook and elegant as a disturbed phoenix",and "not Cao,not Zhen,yet flexible" are respectively the unique aesthetic imagery symbols of Zhuan,Li,Cao and Xing.

书体意象是历史发展和审美追求相互作用的结果，每一种书体都形成了自身特有的美学意象，所谓"画如铁石，字若飞动"、"蚕头燕尾、规矩有则"、"婉若银钩，漂若惊鸾"、"非草非真，发挥柔翰"，即篆、隶、草、行特有的美学意象符号。

In this paper, the research object is the XM18 spherical generator, in order to improve the dynamic behavior of the machine tool, the following aspects have been studied in this thesis: Firstly, based on the elasticity theory and finite element analysis theory, the finite element models of the lathe bed, dovetail, dovetail shelf, headstock, fanlike plank and millhead shelf, which were the main parts of the spherical generator, were built up using ANSYS9.0. And based on the modal analysis theory and FEM technology, the free modal and the constrained modal analysis of the main parts were studied. Accordance to the analytical results, put forword methods to optimize the key parts.

First, the theory of fretting wear and studies on fretting fatigue were introduced and the parametric method was used in the process of creating the model of dovetail joints in UG software. The elastic contact problem is analyzed in finite element method and is used to the parameters' distribution and contact stress of the joint are obtained on the base of ANSYS code. With the effect factor of load frequency, the prediction method of fretting fatigue life of dovetail joint under low and high/low cycle complex load is proposed. The proposed model and the approach were verified by experiments.
