【摘要】 本文采用零维边界元,处理组合体弹性联接,使计算模型符合实际边界约束。由此对组合机身进行结构有限元分析,可比较精确地计算出机身各构件的变形及应力。并通过计算出边界单元的力,研究工作载荷在各构件间的分配,为构件的强度、刚度设计提供较可靠的依据。更多还原

【Abstract】 In this paper the Zero-dimensional bound element is applied to dispose of elastic join of combination s’o that the calculating model will accord with the actual bound binding. For this reason is presented the com -bination frame structural analysis by using finite elemen: that the more accurate strain and stress of frame structures is calculated. Through the coun -ted force of bound elements the working load allotment between structures is studied and a more reliable basis for the design of stuctural strength and rigidity is provided.更多还原
