Method and system for self-locking and fixedly connecting thin plate

The invention relates to a method and a system for self-locking and fixedly connecting a thin plate. The connecting system is provided with a self-locking rivet with a cylinder rod part with a pointed circular ring at the lower end of the cylinder rod part, a blank holder outside the rivet, the thin plate to be connected, and a female die with an annular groove in the lower part of the female die; the thin plate to be connected has two to three layers, and the elongation rate of the lowest layer is more than or equal to 12 percent; the thickness and the strength from the lowest layer to the top layer are gradually reduced; and the thickness of the lowest layer is more than 1 / 3 of the tot l thickness. When a self-locking riveting tool is used, a drive punch hammer and the blank holder pre-press the thin plate, and the self-locking rivet stabs the thin plate after pressurization, so that the lower part of the thin plate is subject to plastic deformation towards the inner part of the annular groove; and a mechanical self-locking structure is formed after expansion. According to the method and the system for self-locking and fixedly connecting the thin plate, a problem that the thin plate cannot be subject to spot welding can be solved; punching and riveting can be achieved at one time, the efficiency is high, and a time cycle for connecting one rivet is three seconds; products can be manufactured without smoke, gas, spark, dust, scraps and noise, and requirements on connection, automatic mass production and environmental protection of automobile light materials; and the connecting method and the system can be used for the fixed connection of thin aluminum plates, metal and non-metal, painted or cladded ferrous metal and the like.

An arch tower axis optimization method for an arch tower cable-stayed bridge

The invention relates to an arch tower axis optimization method for an arch tower cable-stayed bridge, which comprises the following steps: preliminarily formulating an arch tower axis line shape of the arch tower cable-stayed bridge and each section size of the arch tower according to requirements, and calculating the dead weight q of the arch tower; Dispersing the initial arch tower axis into aseries of nodes containing cable tower anchoring points and continuous short-size beam units, and establishing a finite element model to calculate and obtain an initial stay cable force Fi; Decomposing loads transmitted by stay cables on the two sides of the arch tower into vertical loads Vi and transverse bridge loads Hi in a plane where the axis of the arch tower is located; Calculating the length di of each section of the arch tower; Calculating node Z coordinates after arch tower axis optimization to obtain an arch tower axis after first optimization, calculating and determining a final optimized arch tower axis by adopting an iteration method, and obtaining a smooth arch tower axis equation by using high-order parabola fitting. The coordinates of each node of the arch tower axis of the arch tower cable-stayed bridge obtained by the method are very close to the pressure line corresponding to the optimized load of the arch tower axis, so that the bending moment of the arch tower canbe greatly reduced, the arch tower can give full play to the compressive property, and materials are saved.
