Dynamic analysis of interaction between wheel and cover of precast concrete manhole

Lesław Kwaśniewski


The paper presents results of computer simulations for interaction between a rolling wheel and a typical cover of precast concrete manhole used for telecommunication network. Applying the most recent features of computer programs based on the Finite Element Method with the explicit time integration, the work was focused on the realistic representation of the actual problem. In the numerical model the interaction is traced between a rotating, three dimensional, pneumatic wheel and a detailed model of the selected cover with all component materials represented separately. Eleven cases were studied with different types and levels of loading, position of the cover and material representation for concrete. A new sophisticated constitutive model for concrete with a three invariant formulation for the failure surfaces, available in program LS-DYNA, was adopted for some of the calculations. The results allow for estimating maximum stresses and dynamic impact factors featuring dynamic effects of the wheel to cover interaction.
