Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. The production process of aluminum profiles mainly includes three processes: casting, extrusion, and coloring (coloring mainly includes oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, etc.). Aluminum materials are extremely unstable in the air and can easily form oxide films that are difficult to recognize with the naked eye. Due to the different processing methods for aluminum parts, such as casting, direct cutting from extruded sheets, mechanical precision processing, or heat treatment or welding after different processes, the surface of the workpiece will present different states and varying degrees of dirt or marks. Therefore, in the pre-treatment process, the pre-treatment process must be selected based on the actual situation of the workpiece surface. In the pretreatment process, attention should be paid to: although the natural oxide film on the surface of the fine machined parts is only initially formed, the unmachined surface is left with an excessively thick oxide layer formed during the casting process, and a layer of oily sintered coke is formed before the workpiece is transferred to the heat treatment or welding process. The treatment precautions are as follows: (1) The problems to be noticed in the pretreatment process of fine machined parts: although the natural oxide film on the surface of fine machined parts has just formed and is easy to remove, it is greasy, especially in and around the eyelet (added due to lubrication needs during machining). Such parts must be cleaned with organic solvent first. If you directly use alkali, it is not only greasy and hard to remove, but also the fine machined surface can not withstand strong alkali corrosion for a long time, The result will also affect the roughness and tolerance fit of the workpiece surface, which may eventually become a waste product. (2) The issues that need to be noted in the pre-treatment process of casting molded parts. Not all surfaces of cast parts have undergone mechanical processing. Unmachined surfaces have an excessively thick oxide layer formed during the casting process, and some even contain sand layers. At this time, the original oxide film in this area should be removed first using machining or sandblasting methods, or processed after alkali washing. Only in this way can the original oxide layer in the unprocessed area be removed and the tolerance dimensions of the machined area be avoided from changing. (3) During the pre-treatment process of workpieces that have undergone heat treatment or welding, attention should be paid to the following issues: according to the process requirements, the workpieces need to be cleaned with organic solvents before being transferred to the heat treatment or welding process to remove surface oil stains. However, currently, this is generally not possible. Therefore, a ...

Energy is the material basis for the survival of life. It is a major problem faced by mankind in the 21st century. Green energy such as wind power, moderate-scale hydraulic power, bioenergy, solar energy, geothermal energy, etc. are increasingly valued by people. Among them, solar energy is the most potential and inexhaustible clean energy. With the development of the photovoltaic industry, its brackets have been transformed from steel products to aluminum alloy profiles, highlighting its environmentally friendly advantages such as lightness, durability, diversified structures, and recyclability. To this end, a reasonable product structure is designed through mechanical analysis, which can not only meet the usage requirements, but also have a simple and lightweight structure. 1.2 Design requirements: (1) Solar panel specifications: 1650mm×990mm×50mm (2) Number of solar panels installed: 14 ( 3) Solar panel array: 2×7=14 (4) Bracket tilt angle: 30° (5) Maximum wind speed: 42m/s (6) Snow load: 0.65kN/m2 (7) Solar panel load: 0.2kN/m2 (8) Installation conditions: Ground, ground roughness category II (9) Calculation standard: JIS C8955: 2011 (10) Product design life: 20 years 2 Strength design 2.1 Design conditions ①The snow load is 0.65kN/m2, and the maximum wind speed is set to: 42m/s. Seismic loads are not considered. It can be calculated that the vertical snow thickness is less than 1m, which is a calculation for ordinary places. ② According to the above, it can be assumed to be the maximum load in a general place, and the short-term composite load of the fixed load G and the wind pressure load W generated by the storm is used, that is, G+W; the load combination of G+S when there is snow. ③ Calculate the bending strength and bending amount of the material caused by the wind pressure blowing from the front of the bracket (downwind) and the wind pressure blowing from behind the bracket (headwind), and confirm the strength. ④ Maximum height H=2.175m. 2.2 Assumed loads ①Fixed load solar module: Gm =0.2kN/m2; Weight of T-shaped track 110: G2= 1.703×9.8/(1.65/2)=0.021kN/m2; Fixed load weight of single T-shaped track 110 G= 0.2+0.021=0.221kN/m2; ②Wind pressure load: Assume that the wind pressure load of the wind blowing from the front of the array (downwind) is Wp Wp=Cw×(0.6×V0 2 ×E×I) Cw—wind coefficient. This scheme is positive pressure. The calculation formula is: 0.65+0.009θ=0.65+0.009×30=0.92 V0—Wind speed 42m/s E—Environmental coefficient, since H=2.175m is less than Zb=5m According to formula (4), the ground roughness category is II Er=1.7×(Zb /ZG)α =1.7×（5/350）0.15=0.8988 E=Er 2 /m2 The wind pressure load of the wind (headwind) blowing from behind the array is Wp, and the wind coefficient is changed to: Cw—wind coefficient. This plan is negative pressure. The calculation formula is: 0.71+0.016θ=0.71+0...

Not long ago, NASA announced a very avant-garde and technologically advanced propulsion system for future space vehicles. The system is led by NASA's subsidiary, the Marshall Space Center, and is fully known as the Heliopause Electrostatic Rapid Transit System, also known as the Solar Electric Sail Propulsion System HERTS. Is it particularly futuristic to look at the appearance alone? Has it overturned your understanding of aircraft? Structural composition of electronic sails The electronic sail is not as complete as the traditional sail surface, and as the main part of the propulsion system, there are some particularly slender aluminum wires. Yes, you're not mistaken. Those slender wires are aluminum wires. Of course, this is not a common aluminum wire in our daily lives. These aluminum wires are extremely thin and long, with a diameter of 1 millimeter, roughly the same thickness as a paper clip, and they are super long, measuring 12.5 miles, or about 20 kilometers. What is the concept of this length? It is almost the length of 219 football fields arranged together. An electronic sail typically consists of 10-20 aluminum wires radiating from the center to the surroundings. After the rocket reaches the designated position, the aluminum wire is extended from the center to both ends, and two small rockets are used to propel and complete the fan-shaped deployment task of the aluminum wire group. Complete the final deployment form of the electronic sail. The Power Source of Electronic Sails Of course, having such an electronic sail propulsion system is not enough to set sail in space. The important aspect of interstellar navigation is propulsion power. Traditional aerospace engines require their own propellants, which account for a large proportion of the total mass of rockets and seriously constrain the payload and flight distance of spacecraft. Therefore, seeking more effective ways to advance has always been the direction of scientific research. Scientists have turned their attention to the sun, the ultimate energy boss in the solar system. Electronic sails are propelled by the solar wind generated by the sun. Unlike the wind composed of molecules on Earth, solar wind is a stream of supersonic plasma charged particles emitted from the upper atmosphere of the sun, composed of particles such as protons and electrons, and the effects they produce when flowing are very similar to air flow. The density of the solar wind is very thin and insignificant. Generally, in the interplanetary space near Earth, there are several to dozens of particles per cubic centimeter, while the density of the wind on Earth is 268.7 billion molecules per cubic centimeter. However, the strong force of the solar wind is far stronger than the wind on Earth. The speed of the solar wind near the Earth is generally 350-450 kilometers per second, and can reach 800 kilometers per second when strong. It may not feel much just looking at the numbers. You should know that the strongest...
