【摘要】 随着石油、天然气等便于管道运输的能源在国家经济中的作用不断扩大，包括“西气东输”在内的一大批管道工程即将或已经开工，作为重要管道施工机械的吊管机越来越受到重视。但是国内现有的吊管机多是测绘仿形生产，缺乏可靠的理论设计计算，所以其机械质量、性能、吊重等难以满足管道建设的需要。 作为一项计算机辅助工程(CAE)的新技术，虚拟样机技术可以大大地简化机械产品的设计开发过程，大幅度缩短产品开发周期，大量减少产品开发成本，明显提高产品质量，提高产品的系统级性能。 本文在天津建筑机械厂生产的TY160C推土机的基础上，完成了DGSY-25型吊管机的改装设计及强度校核；使用三维实体建模软件UG建立了模型；使用机械系统运动学/动力学仿真软件ADAMS建立了液压——机械一体化的虚拟样机模型，并进行了动力学仿真，验证了设计方案的可行性及结构设计的正确性，为物理样机的制造提供了参数依据；对生产作业过程中的各种危险工况进行了仿真分析，为科学地选用配重类型以防止倾覆事故的发生提供了理论依据。更多还原

【Abstract】 With the development of energy sources industry, energy sources convenient to convey by pipeline, such as petroleum , natural gas , play a more important part in national economy. What’s more, a large set of pipeline projections included West-East Gas Pipelines Projection will start working or have started. So as an important pipeline construction machine, pipe crane is paid more attention. But existing home-produced pipe cranes are mostly imitative, and short of credible theoretic design calculation. Therefore, their mechanical quality, performance and weight-hoisting are difficult to meet the demands of pipeline construction.As a new technique of Computer-Aided Engineering (CAE), the advantages of virtual prototyping technology are as follows. It can simplify the design processes of machine products, shorten the exploit period, reduce cost and obviously improve quality and systemic performance.This paper includes: on the basis of TY160C bulldozer made in Tianjin Construction Machinery Works, completing the design and intensity verifying of DGSY-25 pipe crane; using high-grade 3-dimensional plotting software UG (Unigraphics) to sculpt; using ADAMS (Automatic Dynamic Analysis of Mechanical Systems) to establish virtual prototyping model and do dynamic simulation, and verifying the feasibility of this design precept and provide the basis for trial-manufacture of physical prototyping. At the same time, still simulating all kinds of danger operating mode in the course of production, which provides the theoretical foundation for rationally selecting ballast type to prevent the occurrence of overturn accidents.更多还原
