Low Rolling Resistance (LRR) conveyor systems are generally preferred over traditional conveyors because of better overall efficiency lesser energy consumption required to operate. In this work, the design development and analysis path in the process of downscaling the size of an existent LRR test rig to a compact, portable and desktop-sized model is presented. Simulation has been developed using SolidWorks and finite element analysis is conducted using ANSYS to obtain the deformation, stress and strain of each part of the new design.

Particle Hydrodynamics

New soil models for a tire-soil interaction are developed and compared. A rigid tire model is used to perform an extensive sensitivity study on the previously used Finite Element Analysis (FEA) soft soil (dense sand) to determine the importance of mesh size, soil plot size, and edge constraints. Furthermore, parameters for Smooth Particle Hydrodynamics (SPH) particles are determined for either complete or partial replacement of FEA elements in the soil model. Rolling resistance tests are then conducted for different FEA, SPH, and FEA/SPH soil models. Replacement of FEA elements with SPH particles is isolated as a variable and it is found that using a deeper amount of SPH particles increases rolling resistance while increasing the SPH particle density has little effect on rolling resistance.

The article proposed a kind of new structure for aircraft tire, which includes double firm rings. The aircraft tire of double firm rings was simulated in the instant of landing by finite element analysis, then the simulation result was compared with the one of ordinary aircraft tire. The result indicated that the grounding area and deformation of aircraft tire with double firm rings was less than that of ordinary aircraft tire, which can decrease the rolling resistance and improve high speed performance. In addition, the larger contact pressure located the central region of the contact surface, which can reduce the damage of shoulder rubber and lengthen the life of the aircraft tire.
