The main jobs of this paper are as followed: 1 The reuse of the frame design technology for aircraft assembly fixtures is researched. a frame line part library is built with the templet driven technology, the reuse of the frame line part come true by the tools for instantiation and instance modification. The design resources are effectively used, some repeating work is cut. 2 Two methods to obtain the assembly feature are proposed: the straight way by the Enumeration method and the indirect way by project features to the assembly plane. All of the assembly features of the frame and the adjustable bearings are obtained by these two methods which makes the frame automatic assembly technology for aircraft assembly fixtures come true. 3 The frame automatic assembly technology aircraft assembly fixtures based on assembly features is researched. A binary tree assembly model is used to express the assembly information of the frame for aircraft assembly fixtures, the automatic assembly between the frame, the aircraft and the adjustable bearing is completed within the three steps: distribute, obtain and evaluate assembly feature. Finally, the efficiency of the frame assembly design is proved. 4The frame interpart modeling technology for aircraft assembly fixtures is researched, the intersection methods are concluded and the arithmetic of the single-cut, double-cut and inter-cut intersection is proposed, the interpart fast modeling of the frame design for aircraft assembly fixture come true. 5Based on the researches mentioned before, a sub-system of frame fast design for aircraft assembly fixture is developed on CATIA. The sub-system is used to design the aircraft assembly fixtures in a large aeronautics corporation and make a good- effect.

Since the installation of fire safety is not a part of a building structure and the seismic building design code does not include fire water pipings, the design of them in Taiwan does usually not consider the seismic effect. This study first collected and summarized the relevant seismic design codes and fire control standards from U.S., Japan, China and Taiwan to understand the internationally adopted methods for seismic from designs of fire water pipings. This study also gathered engineering cases and photographs of the installation of the shock resistance hangers of fire water pipings in high technology factory buildings. Then, this study presented a proposal for seismic design principles. we hope this can attract attentions from government authorities and the fire safety business sector and to rise concerns of the seismic design of fire safety installation; and therefore set up a clear and practical criterion for the engineers and finally reduce the damage of post earthquake fires.
