The finite element model of a 0201 V-shaped, U-shaped, and UV-shaped single corrugated board corrugated boxes are established. The stress distribution and strain of the three types of waveform corrugated box to withstand the pressure of the top surface stacking are calculated. Three kinds of corrugated board compression are analyzed. Analysis of the structure shows that the V-shaped corrugated board has good rigidity, U-type corrugated box has good cushioning properties, and the range during which the UV type is a better choice. This is consistent with the experimental results, prove the validity of the finite element analysis, and provide data basis for optimization design of the shape of the corrugated board corrugated waveform.

This study proposes a new correlation improvement technique for the optimum node removal location to get improved modal assurance criterion (MAC) matrix. The technique is applied to updating of the finite element model (FEM) of a structure. The developed routine is tried on a utility helicopter. It is proven that it is capable of showing better performance than the coordinate MAC (coMAC), commonly used in such analyses. Commercial software is utilized for the finite element analysis of the helicopter fuselage and tail. Experimental modal analyses are also performed for updating the model for tail of the helicopter to demonstrate the effectiveness of the new technique.

Abstract This paper presents an adaptive nodal boundary condition scheme to systematically enhance the computational efficiency and circumvent numerical instabilities of the finite element analysis in density-based topology optimization problems. The approach revisits the idea originally proposed by Bruns and Tortorelli to eliminate the contribution of void elements from the finite element model and extends this idea to modern projection methods to stabilize the implementation, facilitate reintroduction of material, and consider additional physics. The computational domain is discretized on a fixed finite element mesh and a threshold density is used to determine if an element is sufficiently low relative density to be “removed” from the finite element analysis. By eliminating low-density elements from the design domain, the number of free Degrees-Of-Freedom (DOFs) is reduced, thereby reducing the solution cost of the finite element equations. Perhaps more importantly, it circumvents numerical instabilities such as element distortion when considering large deformations. Unlike traditional solids-only modeling approaches, a key feature of the projection-based scheme is that the design and finite element spaces are separate, allowing the design variable sensitivities in a region to remain active (and potentially non-zero) even if the corresponding analysis elements are removed from the finite element model. This ultimately means material reintroduction is systematic and driven by the design sensitivities. The Solid Isotropic Material with Penalization (SIMP) approach is used to interpolate material properties and the Heaviside Projection Method (HPM) is used to regularize the optimization problem and facilitate material reintroduction through the gradient-based optimizer. Several benchmark examples in areas of linear and nonlinear structural mechanics are presented to demonstrate the performance of the proposed approach. The resulting optimized designs are consistent with literature and results reveal the performance and efficiency of the developed method in reducing computational costs without numerical instabilities known to be due to modeling near-void elements.

According to the property of contact problem, the calculation formula of contact stress of cross-roller slewing bearing is derived under the action of eccentric axial load. The finite element model of slewing bearing is analyzed in ANSYS, and then the finite element analysis software is used to analyze the contact stress. In this way, the distribution condition of contact stress between roller and rings is obtained. By comparing the finite element analysis results with theoretical analysis results, the correctness of finite element analysis is certified, which provides a guide for the design and optimization of slewing bearing.
