Research on Parametric Finite Element Analysis Method for Escalator Truss

On the premise of ensuring the structural strength and safety performance of escalator truss,in order to improve the efficiency of design and development of the serial escalator truss,a parametric finite element analysis platform for the escalator truss is developed by using the secondary development of finite element method and Visual C++and data interface technology.In this paper,the structural design and strength characteristics of the escalator truss with different parameters are studied according to the requirements of different design,and the strength characteristics of the escalator truss with maximum boundary load are analyzed.The results show that by using the parameterized finite element analysis platform of the escalator,users can get the structural strength results of the serial truss only through calculating the automatic modeling by inputting parameters.The analysis process is greatly simplified and the analysis efficiency is improved.
