接头角板位置对客车三杆结构承载特性的影响

Effect of bracket joint on the rigidity and strength of 3-rod structure of bus body frame

应用有限元方法,计算分析不同数量及不同的接头角板位置对相互垂直的不等宽空间三杆结构的承载性能影响,结果表明,角板平面与载荷力平行时,能有效提高结构的刚度和强度;与载荷力垂直方向时,对结构刚度与强度影响很小;接头角板位置不同,对结构刚度占强度影响也是不同。

Finite element analysis （FEA） was used to analyze the effect of bracket joints in different locations on the rigidity and strength of 3-rod structure. The results indicate that the structural rigidity and strength are enhanced when the plane of bracket joints is parallel to the loading minor effects are exerted on the structural rigidity and strength;that the effect of the vary with position.
