| In this paper, we analyze a variety of input configurations of scissors lifting mechanism on geometry and statics. As scissors lifting mechanism can lift people and goods, it is widely used in equipment of storage, airport, wharf and other places, such as the modern lifting stage, airport catering trucks, platform vehicles and apron-drive unit widespread used in civil aviation, etc. In this paper, we hope to find a relatively good input configuration and optimize design for section of support arm. Obtain the constraints set, with accurate models using uniform geometry and mechanical analysis results. Define the design variables. According to the design requirements and engineering optimization instance, determine the target in the form of a function, the use of genetic algorithms to seek input ideal configuration optimization program and improve genetic algorithm optimization to accelerate the convergence rate. Six different input configurations optimized lightweight design will be studied in this paper, and compare them to get the best option. According to the profile used to model the existing structure, and by simplifying the ideal solution, this paper will give optimization experiment station. On the other hand, a further optimization of the ideal approximation analysis will be done to seek approximate overall optimization.Using MATLAB software to program and verify a variety of scissor lifting mechanism configuration optimized designs. Compared these six relatively optimized designs; we can get the most optimized design of all from this MATLAB programming. Combined with the actual work required, this paper will verify the feasibility of the optimal design. Then design a visual GUI interface for users to directly use, user-friendly cross-sectional shape is selected according to their needs and materials can be run after the most lightweight cross-sectional dimensions. Meanwhile packaged as separate software programs, so that can be run without MATLAB environment. |
