This paper reports on a series of shaking table tests full-scale flat-bottom steel silo filled with soft wheat, characterized by aspect ratio around 0.9. The specimen was 3.64-m diameter and 5.50-m high corrugated-wall cylindrical silo. Multiple sensors were used to monitor the static dynamic response system, including accelerometers pressure cells. Numerous unidirectional performed consisting ...

High densities in bunker silos minimize losses and reduce storage costs; however, the guidelines to attain high densities are based on relatively little research. The objective of this study was to determine those practices or factors most correlated with bunker silo density. Density was measured in 175 bunker silos across Wisconsin using core samples collected at chest height (1.13 m, 3.70 ft,...

With the increasing volume demand of silos, silo diameters are bigger and bigger. However, present wall pressure computation methods are mostly based on small diameter silos. There is little system research on large diameter silos. To solve this problem, systematical research by three-dimensional finite element method on large diameter silos was carried out in this paper. Static wall pressure a...

The paper describes results of FE-simulations of confined granular flow in silos with and without inserts. The numerical analysis was performed with the help of an uncoupled Arbitrary Lagrangian-Eulerian (ALE) approach. The behaviour of the granular material was described with a non-local hypoplastic model. The FEresults of silo flow were compared with experiments in a large-scale silo. Both th...

Deformation of the silo wall due to the single ball impact is modeled in ANSYS. The material in silo, as a Winkler bed, is replaced by spring-damper elements and the spring stiffness and damper coefficients are evaluated of the granular material and wall properties. The granular material deformation under the specified force is measured to evaluate the granular stiffness to be used for determin...

We propose a simple model for arch formation in silos. We show that small pertubations (such as the thermal expansion of the beads) may lead to giant stress fluctuations on the bottom plate of the silo. The relative amplitude ∆ of these fluctuations are found to be power-law distributed, as ∆−τ , τ ≃ 1.0. These fluctuations are related to large scale ‘static avalanches’, which correspond to lon...

Bag silos made at three research farms in 2000 and 2001 were monitored at filling and emptying to determine densities and losses. A total of 47 bags (23 alfalfa, 1 red clover, 23 whole−plant corn) were made, and losses were calculated on 39 of the silos. Dry matter (DM) density ranged from 160 to 270 kg/m3. Dry matter density increased with DM content in hay crop silages on average 2.9 kg/m3−% ...
