“…Multiple studies that evaluate new pallet designs with innovative materials can be found in the literature. These studies show that the application of finite element models allow for preliminary evaluations of pallet performance [37][38][39][40]. Han, White, and Hamner [41] applied the finite element method to better understand and explain the distribution of stresses on a single board of the pallet's top deck.…”

Current pallet design methodology frequently underestimates the load capacity of the pallet by assuming the payload is uniformly distributed and flexible. By considering the effect of payload characteristics and their interactions during pallet design, the structure of the pallets can be optimized, and raw material consumption reduced. The objective of this study was to develop and validate a finite element model capable of simulating the bending of a generic pallet while supporting a payload made of corrugated boxes and stored on a warehouse load beam rack. The model was generalized in order to maximize its applicability in unit load design. Using a two-dimensional, nonlinear, implicit dynamic model, it allowed for the evaluation of the effect of different payload configurations on the pallet bending response. The model accurately predicted the deflection of the pallet segment and the movement of the packages for a unit load segment with three or four columns of boxes supported in a warehouse rack support. Further refinement of the model would be required to predict the behavior of unit loads carrying larger boxes. The model presented provides an efficient solution to the study of the affecting factors to ultimately optimize pallet design. Such a model has not been previously developed. The model successfully acts as a tool to study and predict the load bridging performance of unit loads requiring only widely available input data, therefore providing a general solution.

“…The interfacial composite is the contact area between the matrix and the reinforcing fiber that carries the load received by the matrix to the fiber. The structures of the fiber and the matrix Computation 2020, 8, 2 2 of 11 considerably influence the bonding of the fiber-matrix interface, which also affects the characteristics of the composite structure [9][10][11].…”

The microbond test for natural fibers is difficult to conduct experimentally due to several challenges including controlling the gap distance of the blade, the meniscus shape, and the large data spread. In this study, a finite element simulation was performed to investigate the effects of the bonding characteristics in the interface between the fiber and matrix on the Typha fiber/epoxy microbond test. Our aim was to obtain the accurate mesh and cohesive properties via simulation of the Typha fiber/epoxy microbond test using the cohesive zone model technique. The axisymmetric model was generated to model the microbond test specimen with a cohesive layer between the fiber and matrix. The cohesive parameter and mesh type were varied to determine the appropriate cohesive properties and mesh type. The fine mesh with 61,016 elements and cohesive properties including stiffness coefficients Knn = 2700 N/mm3, Ktt = 2700 N/mm3, and Kss = 2700 N/mm3; fracture energy of 15.15 N/mm; and damage initiation tnn = 270 N/mm2, ttt = 270 N/mm2, and tss = 270 N/mm2 were the most suitable. The cohesive zone model can describe the debonding process in the simulation of the Typha fiber/epoxy microbond test. Therefore, the results of the Typha fiber/epoxy microbond simulation can be used in the simulation of Typha fiber reinforced composites at the macro-scale.

“…In the machinery manufacturing industry, the sensor test equipment manufacturing and design has become a hot spot in the field of mechanical design. At present, the research status of the weighing sensor calibration device is mainly focused on the design and research of its pallet, and the main research methods are theoretical analysis and experimental research, such as the study of static deformation of the tray (Atnam, Lim and Khalil, 2005). Scholars Wang Yanju use of finite element analysis technology to carry out the bending characteristics of the tray (Wang and Lu, 2012), Scholar Sang Jun studied weighing sensor calibration device for the entire loading and unloading tray (Sang, 2012), and the longitudinal device is optimized.…”

For the ubiquitous problem of heavier weight, difficult assembling, low efficiency of the sensor calibration of the sensor clamp device of traditional weighing sensor error calibration device, a new sensor clamp device is designed in this paper. The finite element analysis of a new type of fixture is carried out by using the finite element analysis technology, the results show that the weight of the new sensor device is reduced by 7.46% compared with the traditional fixture, but also has a higher stiffness and strength. The dynamic characteristics of the sensor fixture is analyzed and studied through the modal analysis, the results show that the third and fifth mode shape have the greatest impact on the cylinder and the cylinder head which connected to the transverse junction. The above research can provide some theoretical reference and engineering reference for the design of other sensor fixture.
