【摘要】 垃圾中转是生活垃圾处理过程中的一个关键环节。本文对新型地平式城市生活垃圾中转装置进行了深入研究，创新设计出了液压斜拉全封闭地平式垃圾中转装置，对设备的若干问题进行了较为深入系统的研究，开发了具有自主知识产权的生活垃圾中转装置。 确定了举升机构设计目标及要求，提出了对举升机构进行详细的类型综合的方法，在此基础上按设计目标要求对所有方案进行了优选，最终确定了液压斜拉式生活垃圾举升机构最优方案。 对生活垃圾中转装置进行了结构设计，在此基础上对其进行静力学分析，确定装置优化设计中的设计变量、约束条件、目标函数，并建立多目标优化的数学模型。利用MATLAB及其优化工具箱对优化模型求解，确定了相关构件的结构参数，为动力优化和设计打下了基础。 按照设计目标要求，对垃圾集装箱运动轨迹进行改进，设计出更加合乎设计目标要求的曲面运动轨迹，与设计前相比液压缸举升力降低了23.8％。 运用虚拟样机技术建立了液压斜拉举升装置的物理模型，对举升装置进行了运动仿真分析。在此基础上，对举升机构进行了参数化建模，通过参数优化重新确定了举升液压缸的位置和结构参数，实现了举升机构的动力优化设计，并据仿真过程中发现的问题对装置进行了改进，液压缸举升力比优化改进前降低了17％，油压特性更加平稳。 分析了生活垃圾中转装置的特点与要求，全面研究了中转装置各个功能模块的组成，并对相关模块进行了详细的设计。 本研究项目是山东省自然科学基金项目(2003ZX005)的一部分，所设计的液压斜拉式生活垃圾中转装置已申请国家发明专利(申请号：200510045131.2)。更多还原

【Abstract】 This paper has made deeply analysis and studied on the new-style underground MSW transitional station, and put forward a new kind of concept named stayed transitional station with hydraulic pressure in a creative way.The structure of lift-discharge mechanism is analyzed synthetically. According to goals and requirements, other projects are rejected and stayed transitional station with hydraulic pressure is decided as the best project.Basing on structure designing for the MSW transitional equipment, statics analysis is done and a multi-objective optimization mathematics model is also built. Structure parameters of relative components are confirmed by using MATLAB and its Optimization Toolbox.According to the goals and requirements, the track of waste container’s trailing wheel gets improved to satisfy the designing requirements; the maximum pressure acting on the hydraulic cylinder has reduced by 23.8%.Using virtual prototype technology, this paper has built physical models for this equipment and implements dynamic simulation analysis. This lift-discharge mechanism adopts parametric modeling by which position and structure parameters of its hydraulic pressure cylinder are redetermined, and its dynamical optimization design is also realized. The maximum pressure acting on the hydraulic cylinder has reduced by 17%.The characteristic and requirement of this MSW loading equipment is analyzed, the component of every module is studied comprehensively, and every relative model is designed particularly as well.更多还原
