“…The larger the particles, the more the deformation energy is dissipated in the matrix and in the reinforcing elements, each of them overtaking a different deformation energy, depending on the viscous-elastic characteristics of the wood particles and of the polyester resin [6] and [10]. Before the accelerated weathering, in the structure of the lignocelluloses composite there are phenomena specific to wood particles, matrix and interface between matrix and wood particles, which leads to variations of the internal frictions due to the physical connections (of the Van der Waals type) and chemical one situated in various stages of polymerization [14] and [15]. The UV radiation leads to a porous surface due to migration of chemical compounds (Fig.…”

“…These mechanical parameters are lower for composites with larger particles [12] and [13]. The type of resin using in composite plays an important role in increasing the mechanical properties (tensile, bending and shear), noticed by [14] and [15]. Until date, the references about modification of mechanical and morphological properties of lignocellulosic composite because of UV radiation are relatively limited.…”

The aim of this paper is to evaluate the mechanical and surface properties of lignosellulosic fibres reinforced composite before and after photo-degradation exposure. This leads to decrease the mechanical properties of composite as modification of hydrophobic behavior of matrix. In the study, the lignocelluloses specimens were obtained by mix polyester resin type 440-M888 POLYLITE, in a volume percentage of 25 %, with different wood particles classified by size classes. The samples were exposed to UV-A radiations with a wavelength λ of 365 nm for 168 hours (7 days). The evaluation of the surface energy was carried out by the θ contact angle method. For mechanical properties, the dynamic mechanical analysis (DMA) was used to determine the variation of storage and loss modulus. The results showed that UV radiation induced structural morphological instability, which leads to hydrophilic effect. The loss modulus recorded an increasing with increases of wood particles sizes.

“…The proposed cell wheel seed-metering device for corn was tested in accordance with the Testing methods of single seed drills (precision drills) (GB/T 6973-2005) with rotational speed of the seed-metering device, hole diameter of the seed plate, and hole pitch of the seed plate as the independent variables. Response values were the qualification index, miss-seeding index, and reseeding index [23][24][25]. The test was carried out in the Agricultural Machinery Laboratory of Northwest Agriculture & Forestry University using a self-made cell wheel precision seed-metering device, as shown in Fig.…”

In this study, a wheel seed-metering device with cells for corn was built to enhance seed-metering performance and shorten the design cycle. The actual seedmetering process was analyzed and the three main factors influencing seed metering were obtained: rotational speed of the seed-metering device, hole diameter, and hole pitch. With the three factors as the test factors, and the QFI, MISS and MULT index as the test indexes, the multiple quadratic rotation orthogonal combination test was carried out. Using Design-Expert 8.0.6 to analyze the test data, the mathematical model between the test factors and the test index was obtained. The parameter optimization results indicate that optimal performance of the seed-metering device can be achieved under a rotational speed of 30.32 rpm, hole diameter of 13 mm, and hole pitch of 45 mm, qualification rate, miss-seeding rate, and reseeding rate were 94.99%, 1.93%, and 3.08%, respectively. Under the optimal parameter combination, the field test proved that the qualification rate, miss-seeding rate, and reseeding rate were 91.81%, 3.08%, and 5.11%, respectively. The test results were close to the optimization results, which could show the agronomic requirements of the precision sowing of maize.
