电梯不同承载状态时的结构性能研究

Structural Performance of Elevators at Different Load Bearing States

电梯随着城市化建设、高层建筑的普及成为人们广泛使用的特种设备,其安全性对人们的生产生活具有重要的影响作用。电梯的结构复杂,在使用过程中面临多种不同的承载状态,对其结构的承载性能具有较高的要求。针对电梯的结构性能,采用ANSYS有限元仿真的形式对满载、超载、偏载状态时的应力分布进行计算分析。结果表明,轿架组件中上梁和下梁的最大应力出现在超载工况时,立梁的最大应力出现在偏载工况时,轿架组件的强度均满足电梯的使用安全需求。在电梯的设计使用过程中,应据此对不同的结构组件进行承载性能分析,以保证电梯的运行安全。

Elevators have become widely used special equipment with the popularity of urbanisation and high-rise buildings,and their safety has an important impact on people's production and life.The structure of lift is complex,and it faces many different bearing states in the process of using,which has high requirements on the bearing performance of its structure.For the structural performance of the lift,ANSYS finite element simulation is used to calculate and analyse the stress distribution in full load,overload and partial load states.The results show that the maximum stress of the upper and lower beams in the car frame assembly occurs in the overload condition,and the maximum stress of the vertical beam occurs in the partial load condition,and the strength of the car frame assembly meets the safety requirements of the lift.In the process of designing and using the lift,different structural components should be analysed accordingly for their load-bearing performance to ensure the safe operation of the lift.
