摘要:

对动车组座椅弹性支撑的粘接接头进行了设计,采用Bigwood法测算出胶层在接头边缘部位承受的极限载荷,通过试验对两种备选胶粘剂老化前后的强度进行了测试并计算其特征参数。研究结果表明:粘接面长度、宽度值至少应大于96 mm时,可以避免应力集中;极限载荷约为5.6 MPa;胶粘剂A特征参数为-3.25 MPa,胶粘剂B为7.75 MPa,胶粘剂B可满足接头要求。

Abstract:

The bonded joint for elastic support of EMU seat was designed,and the maximum load of adhesive layer was calculated by Bigwood method on the edge of the joint. The strength of two alternative adhesives before and after aging was tested,the characteristic parameters were calculated as well. The research results showed that the stress concentration could be avoided when the length and width of bonding surface were at least greater than 96 mm. The maximum load was about 5.6 MPa. The characteristic parameter of adhesive A was -3.25 MPa,the characteristic parameter of adhesive B was 7.75 MPa,indicating that adhesive B met the joint requirements.
