摘要
为改善某款新设计的商用车运输半挂车尾部举升机构的力学状态,提高机构的可靠性和运动稳定性,对机构运动和受力状况建立了数学模型,以油缸力最小为优化目标,利用ADAMS对此机构进行仿真求解,使用MATLAB优化工具箱中的fmincon函数对模型进行优化。综合分析了仿真和优化数据,给出了优化目标与优化点之间的关系曲线。结合工程实际确定了最优方案。优化结果表明:油缸力与初始方案相比下降了10%,有效地提高了举升油缸工作的可靠性,改善了机构的性能。
In order to improve the mechanical status of the lift mechanism of a new commercial vehicle transportation semi-trailer, enhance the reliability and kinetic stability, the mathematic model for motion and force analysis of the mechanism is built. Taking minimizing the cylinder force as a optimization target, simulation of this mechanism is carried out using ADAMS, and optimization of the model is solved by fmincon function in optimistic toolbox of MATLAB. According to the data of simulation and optimization, it was given the relation curves between the optimization object and optimization point. The optimum decision is proposed based on project. The results show that the cylinder force is down by 10% compared with the preliminary design, which can improve the reliability of the cylinder, and enhance the performance of the mechanism effectually.
