摘　　要：基于有限元软件ANSYS中的APDL语言,以国内在建的跨度最大的大型平开弧门为例,分析了在静荷载作用下,主支臂夹角对闸门结构的影响,确定了最优的支臂夹角,并与传统的平面简化方法建议的主支臂夹角结构进行了计算比较。结果表明:主支臂夹角为最优支臂夹角时结构的静力学性能更好。在此基础上,结合传统的平面设计方法对主支臂进行了稳定性计算分析,为主支臂稳定性计算提供了新的设计思路。所做研究可用于大型平开弧门或其他同类弧门结构的支臂设计计算。Based on APDL language in finite element analysis software ANSYS,it took one large-span horizontal-rotation gate under construction,which was the largest of this kind nationwide,for example to study the influence of the angle between struts on structure by static loading,and ascertained the optimum angle. For further validty,it also made comparsion of mechanical properties between the structure with the optimum angle,and with the angle advised by traditional way. The results indicated that the static performance of structure with optimum angle was better. On this basis,it provided with a new way for stability calculation on struts,combined by traditional design method. The research was useful to the strut design on the large-span horizontal-rotation gate or other similar structures.
