Abstract: Aiming at the problem that it was difficult to stress analysis of escalator truss structure which suffered static, dynamic and other different load, a comprehensive study was executed. The static characteristics of escalator truss were carried out by means of theoretical deduction, simulation analysis and experiment research.Firstly, the statics equation of the whole truss was deduced and simplified by using finite element analysis(FEM). The thin-walled welding structure was rationally simplified by using ANSYS. Then, the initial conditions were parameterized by using APDL parameterized language. The stress simulation analysis of metal truss was carried out under various load conditions. The analysis process included modeling, material properties, constraints, load combination, solving process etc.. The deflection and stress of the whole structure were calculated. The stress of single stressed member and the stability of compression member were studied. Finally, the test platform was established to perform the truss deflection and verify the simulation results. The results indicate that the difference between the simulated value and the measured value is only about 5%. The two values are almost identical. These two values have high reliability. It shows that the simulation method is suitable for escalator truss structure. This simulation method lays a good foundation for further optimization and analysis of this kind of steel structure.
