基于有限元的电梯承重梁焊接头稳定性研究
摘要
Abstract
In order to study the stability of the welded joint of the elevator load-bearing beam during the maximum acceleration,this paper analyzes the elevator model,carries on the force analysis to the elevator system,establishes the dynamic mechanical model of the elevator during operation;and according to the actual operating condition of the elevator system,this paper establishes the dynamic model of the welded joint of the elevator load-bearing beam,and analyzes the mechanical characteristics of the welded joint at the maximum acceleration.Secondly,the actual operation parameters of the elevator load-bearing beam are simulated and analyzed using the Explicit solver of the ABAQUS finite element analysis tool.the results show that there is a large stress concentration zone in the welding head area of the load-bearing beam,and the stress in this area is greater than that in other parts,the stress at the contact fulcrum of the welded joint of the load-bearing beam is greater than that on the back,the stress concentration decreases gradually from the welded joint to the two ends of the load-bearing beam,and the maximum stress appears in the welded joint area.It is calculated that the welded joint is the most loaded part of the whole load-bearing beam during operation,so the stability of the welding head of the load-bearing beam is the key factor to ensure the normal operation of the elevator system,which provides a basis for the welding and installation process of the elevator load-bearing beam.关键词
