Study on the Internal Force and Deformation of Double-System Composite Guideway for Monorail Transit Based on Energy Theory

Abstract

To further investigate the impact of prestressing on the internal force and deformation of the double-system composite guideway (DSCG), theoretical equations for internal force and deformation were established based on the principle of energy variation. The theoretical results were validated through finite element modelling and elastic analysis methods. The proposed DSCG theoretical model, derived from the energy method, effectively addresses the influence of symmetric and asymmetric loads on the internal force and deformation of the guideway. The findings indicated that the ratios of interface slip, axial force, and vertical deformation under the two loading conditions were 1.16, 1.06, and 1.06, respectively, showing close agreement. The prestressing effect significantly impacted the mechanical behaviour of the guideway, particularly the vertical deformation, with a maximum influence of 4.92%. Moreover, the results of the energy and elastic analysis methods exhibited a high degree of consistency, with the maximum deviation in the calculated internal force and deformation results not exceeding 3%. This research fills a gap in the theoretical study of the DSCG and provides valuable insights for developing multi-system monorail transit systems.
