Vibration absorbers are employed for both structural safety and comfort reasons. This paper explores a novel absorber which uses the sloshing of granular particles to dissipate energy in a rolling container. Some of the parameters which affect energy dissipation have been experimentally studied. Detailed description of one experiment is given. Further work involves numerical exploration.

in this study, the performance of different cultivation methods on sugar beet fields was evaluated. eight treatments were considered: a) use of a rolling cultivator twice during the growing season; b) use of a rolling cultivator three times during the growing season; c) use of a crescent cultivator twice during the growing season; d) use of a crescent cultivator three times during the growing s...

The discrete element method (DEM) has been used as a popular simulation method in order to verify the designs by visualizing how materials flow through complex equipment geometries.  Although DEM simulation is a powerful design tool, finding a DEM model that includes all real material properties is not computationally feasible.  In order to obtain more realistic results, particle energy loss du...

The rolling process is an excellent method for processing new high performance polymers. Skew rolling, as a highly accurate and highly efficient rolling technology, has been commonly used to enhance mechanical properties and productivity. However, the complexity of the mechanics in the skew rolling process of polymers is a significant challenge for manufacturers and researchers. In this work, m...

In this research, the effect of the amount of strain and rolling temperature on the microstructure and the hardness of the explosive bonding of 304 stainless steel- copper sheets was investigated. Explosive welding was performed with two explosive thickness (46 and 79 mm) and stand-off distance (2 and 3 mm). The results of the optical microscope after welding showed that all samples had a commo...
