内容简介：

16吨铁路专用起重机设计摘要起重机械用来对物料作起重、运输、装卸和安装等作业的机械设备，它可以减轻体力劳动、提高劳动生产率和在生产过程中进行某些特殊的工艺操作，实现机械化和自动化。起重机械运送的物料可以是成件物品，也可以是散料或者是液态的。起重机受的载荷是变化的，它是一种间歇动作的机械。起重机一般由机械、金属结构和电气设备等三大部分组成，机械方面是指起升、运行、变幅和旋转等机构，即起重机一般是多动作的。铁路起重机操作的模型工作空间需求可以将与空间的冲突和危险有关的延迟减到最少。为了熟悉空间冲突相关操作, 研发工程师需要做模型并且说明有关时间空间的起重机的行为，跨越时间在动态的工程环境里面协调他们。判断设备关于空间的冲突的现在的方法是以动态设备运动的断续事件模拟为基础。使用此方法发现空间冲突的准确性可能是错误的自从它为模拟时间增量的比率被使用者设定。这只体现在操作期间移动起重机占领的工作空间的方式。它也讨论评估方法的效力在识别空间的冲突和在移动的起重机之间与建筑成份方面。关键词 机械 设备 载荷 支承 液压 起重机 工作空间 16 tons of special railway crane designAbstract Hoisting Machinery used for materials for lifting, transporting, handling and installation of mechanical equipment operation, which can reduce manual work, improve labor productivity and the production process for certain special techniques and mechanization and automation. Hoisting Machinery transportation of materials can be as items, it can also be a bulk material or a liquid. By the crane load of change, it is a batch of mechanical movements. Crane by general machinery, metal and electrical equipment such as three major components, machinery is in the case of lifting, running, luffing and rotating body, the crane is usually more moves. Modeling workspace requirements related to mobile crane operations could minimize delays associated with spatial conflicts and hazards on construction sites. To identify spatial conflicts related to crane operations, project engineers need to model and reason about spatio-temporal behaviors of cranes and coordinate them within a dynamic construction environment across time. Current approaches for identifying equipment related spatial conflicts are based on discrete-event simulation of dynamic equipment motion. The accuracy of spatial conflicts detected using such approaches can be error-prone since it depends on a rate of time increment for the simulation to be set by the user. This paper presents an approach for generating workspaces that encapsulate spaces occupied by mobile cranes moving during an operation. It also discusses an assessment of the effectiveness of the approach in identifying spatial conflicts bet
