You can find out it is the major temporary work, such as formwork, rebar jig, equipment etc. during the FPLM construction, in which the cost of the inner mould and outer form of box girder, the steel form of pier and pierhead of substructure, the rebar jig as well as the launching equipments are quite high. The quantity of those equipments was always depended on experience in the pass time. Therefore the more of the form quantity is used the higher of direct costs would be spent. On the other hand it would be reduced the capacity of production if the equipments are insufficient.
在全跨预铸工法中所使用的生产设备仔细观察可发现，预铸工法中假设工程(如模版、钢筋加工架以及施工机具等)所占比例相当高，其中有箱型梁的内模与外模床、下构的柱钢模、帽梁钢模、钢筋加工架、吊装机具等所占的成本相当高，以往设备数量多寡均以经验来取决，因此假如模版数量过多直接成本随之提升，反观模版资源数量不足时又会造成生产力降低情况发生。

The static and dynamic characteristics of the beam of a gantry-type machining center are analyzed by means of ADAMS and ANSYS. Considering effect of gravity and cutting forces, the static deformation of the beam is obtained after calculating the interacting forces between the guide and the slide block by ADAMS. Moreover, the contact parameters of the guide surface are acquired by dynamic tests and parameter identification, then they are applied to the simulation model of the beam-slide box system, whose natural frequencies and modal shapes are achieved by modal analysis. Furthermore, the effect of changes of the contact parameters on the dynamic behavior of the beam-slide box system is also investigated.
