折线先张法预应力混凝土梁长期变形试验研究

通过对两根置于室内近似标准环境、一根置于室外自然环境中的长7.5 m折线先张法预应力混凝土梁长期加载,对跨中挠度进行了600d的量测,绘制了跨中长期挠度及长期挠度系数时程曲线,对其影响因素进行分析.采用Datafit软件对长期挠度系数时程规律进行了数值分析,建立了以混凝土徐变“先天理论”为基础的长期挠度系数工程实用表达式.对该公式进行了精度分析表明误差在±10％以内,并指出了其该类梁长期挠度增大系数终值ηθ可取为2.15,可供折线先张法预应力混凝土梁进行长期挠度预测时参考.

Post-processor development for a turning and milling composite machine tool

The accomplishment of a turning and five-axis milling in only one setup is extremely useful and is possible on a turning and milling composite machine tool. In this work, we present a control algorithm and develop a post-processor for this machine, which has six linear and three rotary axes. To calculate a generalized kinematics model, coordinate systems are established by analyzing the basic kinematic chain relation of the turning and milling composite machine tool. The two vectors, which control the motions of the cutter contact workpiece, are simultaneously transformed to provide the algorithms of the rotary angles and motion coordinate. A special post-processor written in JAVA language is developed according to the proposed algorithm. To evaluate the effectiveness and accuracy of the developed post-processor, a specimen (blade) is used in the cutting simulation and real machining experiment. Experimental results showed the effectiveness and accuracy of the proposed algorithm. Furthermore, Compatibility is improved by adding new functions such as change of target machine, cutter location data change, workpiece origin offset, and cutting feed rate control.
