Grain is extremely vulnerable to external loads during production and processing, resulting in the deterioration of grain quality. Deteriorated not only affects economic value but also safety storage. This has a very important relationship with biomechanical properties grains. It great significance explore mechanical under different conditions analyze between its physical chemical for improving processing eating In this paper, research methods grains are reviewed. Various factors influencing cereals were analyzed. The internal organizational structure was discussed. paper puts forward shortcomings current on prospect analysis importance future development order provide reference reducing crushing process.

An experiment-informed discrete particle simulation study was performed to investigate the role of flexural particles in shear flow milled pine residues. Physical anatomical fraction samples were tested an FT4 powder rheometer. A chip model for bark/stem chips and a fiber needles proposed DEM. The simulations show mixed fibers/chips require higher force torque drive than pure or fibers. mass flexibility fibers reveal nonlinear inter-dependency on impacting fibers/chips. Polydisperse well match needle-rich attributes, while polydisperse agree reasonably with bark/stem-rich samples. DEM indicates that flowability residue biomass is determined collectively by various material attributes fractions, which must be considered when developing preprocessing methods conversion-ready adequate handling performance.

The interaction between Caragana korshinskii Kom. (CKB) branches and crushing machinery is complex, requiring a detailed mechanical model to effectively describe the fracture characteristics of CKB during crushing. This study aims develop such using discrete element method simulate elastoplastic behavior CKB. A for was established based on its characteristics. incorporates stages, including elastic, elastoplastic, fully plastic phases stem parameter calibration employed, combining physical experiments with simulation refine model. key binding parameters were optimized best properties under various loading conditions. optimal flexible identified as: normal stiffness 3.67×1010 N·m-3, shear 3.42×1010 critical stress 6.57×108 Pa, radius 0.78 mm. successfully replicated elastic stage force-displacement curve in compression tests an error only 0.24%. discrepancies simulated actual forces 2.79% compression, 4.68% bending, 4.14% shear, 8.64% tensile tests, showing good agreement experimental results. developed accurately simulates providing valuable insights into mechanism process demonstrated that proposed DEM can be effective tool exploring optimizing

A discrete element method (DEM) based approach is used to study the relationships between material attributes (MAs), processing parameters (PPs), and quality (QAs) for knife milling of maize stalks. An approximate DEM shape model was conceptualized on real stalks calibrated experimental bending test data flexural properties (elastic stiffness, elastic angle limit, elastoplastic ratio, etc.). simulations stalk comminution in a Jordan Reduction Solutions ("JRS") mill were performed investigate MAs (maize size breakage stress limit), PPs (impeller rotational speed), QAs (mass throughput output particle distribution (PSD)). The results suggest that length has little influence mass PSD, whilst with larger cross sections tend generate sizes milled particles given same limit. Both show faster impeller rotation (or higher power) does not necessarily or smaller especially correlations these MAs, are found highly stochastic, though limit dictates throughput, regardless size. DEM-predicted tended match coarse PSDs sieve but showed weakened fidelity finer material, indicating potential further improvement.

Caragana korshinskii Kom. branch (CKB), a vital biomass source in northwest China, has not been thoroughly studied terms of its bending fracture mechanics. This research aims to establish nonlinear constitutive model that clarifies the behavior CKB when subjected loads. The process was characterized through three-point test, revealing stages elastic deformation, elastic-plastic transition, and plastic fracture. A power-enhanced combined with continuous damage mechanics theory used develop an intrinsic model, from which equations governing evolution were derived. model's accuracy validated simulations Abaqus/Explicit, showing various growth sites demonstrated distinct behaviors. At critical strain, cumulative led reduction effective modulus, curve exhibiting power function trend. parameters derived fitting, yielding coefficients determination (R²) exceeding 0.99. consistency between trends observed actual tests simulations, along peak force error 7.7%, finite element reliability confirmed accuracy.
