Guide rails are important part of the elevator guide system, which is significant to its dynamic characteristics that influence the vibration of the elevator system. In this study, the researchers set up a guide rail, guide shoe and car coupling system model which is based on the interaction relationship between guide rail, guide shoe and car. The influence of the three parameters such as the length, weight per unit length and the bending stiffness on the dynamic characteristics of the guide rail is analyzed by applying above model, using the step-by-step integration integral method under the discrete variables. The results showed that weight per unit length affects the quiver of the guide rail. The bending stiffness of the guide rail mainly affects the vibration displacement, the length, which has a significant influence on the vibration displacement and the quiver of the guide rail. The results reveal the inherent law between the structural parameters and the dynamic characteristics, which will provide theoretical guidance for the manufacture and selection of the guide rail and the design of the elevator.
