【摘要】：发展城市地下停车空间是解决停车需求与城市规划、城市管理和交通治理之间矛盾的有效方法。现行的立体车库存在占地面积大、能耗高、噪声大、存取车时间长、不易组合形成车库群等缺陷,而深井式立体车库是一种在地下建造的机电液一体化式立体停车设备,具有土地利用率高、库容比大、能耗低、噪声小、智能化程度高、能因地制宜地组合成车库群的比较优势,是机械式立体车库的发展方向。以适合X~C型汽车停放的智能化PSC8CK-4ZT型深井式立体车库为蓝本,阐述了其功能原理,论证了单库和库群的比较优势。分析了该型车库机械系统及其零部件在设计、制造、使用和维护中存在的问题,运用现代设计分析方法及并行工程理论,对其进行了技术改进。针对升降动力系统,为满足对重失效时的最大驻车制动扭矩要求,对液压马达及法兰螺栓组进行了选型优化及改进设计,提升了升降动力系统的安全性;运用移植创造、组合创新理论,设计出基于摩擦防松形式的对顶式防松方法、基于机械防松形式的多螺栓防松方法,提升了车库的运行可靠性;基于移植创新理论,设计制造出断开式扭簧自动消隙同步装置,消除了由于偏载引发的“闷车”现象,提升了运行安全性,并通过有限元静力学分析,提升了同步装置的性能重量比;运用并行工程理论,设计出高精度齿距控制规,选用了高精度磁性直角水平仪,使齿条制造、安装及维护难度大大降低。针对举升横移系统原设计液压举升装置控制精度不佳现象,重新设计了三种举升装置同步方案解决四缸举升不同步问题,有效的保证了举升动作的同步精度及运行的平稳性。基于车库各机械系统的设计现已逐步形成由不同零部件组合的多种方案的事实,为充分彰显深井式立体车库的特色优势并推广应用,本文采用系统工程分析方法,确定了以综合考虑各系统或总成的技术特性、运行特性、经济性和社会性,构建多因素分析与评定模型,并采用强制判断法确定了各评价目标的加权系数。组织了设计制造工程师、现场施工人员、运行维护人员、开发商和用户代表等,对各组合方案评分,通过对评定模型的求解,优选出各方面性能综合最优方案,从而使机械系统在加工、装配、运行、维护、成本控制和绿色环保等方面达到和谐统一,为深井式立体车库的价值优化和社会推广的分析研究提供了依据。为保障多因素分析与评定工作的高效有序进行,本文基于MATLAB R2010b平台,设计开发出深井式立体车库机械系统综合评价软件,集成加权系数设置、组合方案评分、机械系统总评价、数据维护等模块功能,实现了评价过程的信息化。
