Belt conveyor parts deformation research and renovation engineering

The finite element models were built up using plate elements for all structural parts (H beams, C-channels, pipes, support parts, covers, flanges). Beam elements were used for idlers, bolts, bolt connections; rod elements - for top flange connections; rigid RBE2 (spider) elements - for constraint connections. Type of mainly used plate elements – 4 nodes PLATE Nastran element.

A few existing conveyor constructions were analized due to significant deformation of some structural parts, particularly "cheek" plates.

Static load was taken into account by the assumption of longitudinal distribution of the cargo equal 560 kg/m.

Approximate size of plate element – ±20 mm.

For detailed analysis of the heavy loaded bolting flange connections, a few such locations were modeled with a "fine mesh" style using 3D Hex elements.

 

Deformations, VonMises stress, and contact pressure were analyzed in these case studies. Relevant recommendations were developed and issued to the client's engineers.
