“…Many authors focus on experimental research when analyzing the effect of gluing technology factors on the bearing capacity of cellular structures [17]. Experimental determination of the bearing capability of adhesive connections of cellular structures in terms of transverse stretching is implied by a series of standards [18].…”

“…For solar panels, the thermal conductivity performance [9], compression strength [7], shear strength [27], and weight of the panels are important. The temperature difference, compression strength, shear strength, and weight were lower, and the temperature difference, strength, and weight of the structure were better; hence, the performance of the honeycomb aluminum plate should be investigated comprehensively.…”

“…The honeycomb aluminum plate cannot be directly used in the panel or satellite structure, and it is necessary to add inserts in its interior. As the inserts directly determine the mechanical properties of the honeycomb aluminum plate, they are a critical component of the honeycomb aluminum plate [24][25][26][27][28][29][30][31]. When inserts are added to the honeycomb aluminum plate, local stress concentration will increase and cause damage to the structure.…”

In this paper, a new method of replacing the conventional honeycomb aluminum panel with 3D metal printing on the microsatellite is presented. The multiobjective optimization method is used to optimize the temperature difference, compression strength, shear strength, and weight of the new type of solar panel structure. The relationships between the structural parameters and optimization targets are established, and the influence of five factors on thermal and structural properties is analyzed. Finally, a group of better structural parameters of the panel is obtained. The relative deviations between simulation analysis and model are 27.45%, 6.12%, 1.365%, and 3.27%, respectively. The optimization results show that the regression model can be used to predict thermal and structural properties of the panel, and the establishment of the model is effective. The analysis results show that the performances can be improved by 91.62%, 46.94%, 17.91%, and 10.28%, respectively. The optimized results are used for 3D metal printing, and the new type of solar panel is obtained. It is proved that the method can effectively improve the thermal and structural properties of the panel and can effectively shorten the development and manufacture cycle of the panel and also reduce the cost. It has high engineering application value.

“…Since it is noncontact, nondestructive and has wholefield measurement characteristics, it has been widely used in many areas (Huang et al 2007, Labbe 2007, Sun 2007, Yang et al 2007, Schoeberle et al 2008. Wang et al (1996) first proposed amplitude fluctuation electronic pattern speckle interferometry (AF-ESPI) to enhance not only the contrast of fringe patterns but also to enhance displacement sensitivity to measure dynamic objects under harmonic excitation.…”

This study utilizes a tweeter to provide a source of harmonic vibration for use in the noncontact excitation method. Sound is transmitted through air to generate a resonance mode shape in optical diffuser films. The amplitude fluctuation electronic pattern speckle interferometry is adopted to capture the image of resonance mode shapes and corresponding natural frequencies of the optical diffuser films. Furthermore, the density of the optical diffuser films is measured using a pycnometer, and the Young's modulus of the films is determined using a micro-tension and a compression testing system. The Poisson's ratio of the optical diffuser film is thereby determined from the data on the first six natural frequencies of the diffuser film, its density, and its Young's modulus. The finite element method is employed to compare the experimental data on the natural frequencies of the films. Finally, optical diffuser film is measured in a high temperature, high humidity environment to elucidate this environment's effects on the mechanical properties of the films. Experimental results reveal that the Young's modulus of the optical diffuser films declines as the temperature increases accompanying warps and winkles. The optical diffuser films under high humidity and develop more air bubbles inside the films. The detection of luminance of diffuser films is discussed. Applications of these combined methods to experimental data are demonstrated.
