摘要该毕业设计主要研究初步设计双车五环过山车的运动学和动力学分析,其安全性能是否满足GB8404-2008《游乐设施安全规范》的要求。通过SoildWorks建立小车模型和人体模型并组装,导入UG后将组件拆分成左轮,右轮,轮桥,车身,人,连接叉,连接杆7个部分(一节车厢),最终导入到大型力学分析软件Adams中,通过添加各个运动副和约束条件(如摩擦力,刹车力等),形成模型的完全建立。另外需要指出的是,由于该毕业设计着重研究小车的运动学和动力学特征,对轨道并无实体模型的需求,故该毕业设计中的轨道模型是在Adams中建立的两条样条曲线。完成力学仿真后,对该游乐设施的运动学和动力学进行安全性评估,并未轨道结构提供载荷数据。84699 毕业论文关键词 双车五环过山车 设施模型 Adams力学分析 安全评估 毕业设计说明书(论文)外文摘要 Title The kinematics and dynamics analysis of two ring roller coaster Abstract The graduation design of kinematics and dynamics analysis is the study on the preliminary design of double car ring roller coaster,Whether the safety performance meets the requirements of GB8404-2008 "safety standard for recreational facilities,The car model and the human body model are built by SoildWorks,Imported to UG after components will be split into revolver, right wheel, axle wheel, body, and connection fork, connecting rod 7 part (a carriage),Eventually introduced into the large mechanical analysis software Adams,By adding various motion pairs and constraints (such as friction, braking force, etc。),Complete establishment of the model。And it needs to be pointed out,Since the graduation project focuses on the kinematics and dynamics characteristics of the car, there is no demand for the physical model of the track, so the track model of the graduation design is the two spline curve in Adams。 After the mechanical simulation is completed, the kinematics and dynamics of the recreational facilities are evaluated, and the load data is not provided by the track structure。 Keywords Two car ring roller coaster Facility model Adams mechanical analysis Security assessment 目 次 1 引言 1 1.1 课题意义 1 1。2。1 国内背景 1 1。3。2 国外背景 2 1。3 研究过程中技术问题 2 1。4 采用的解决方法和措施 3 1。5 联合仿真技术 3 1。6 本章总结 4 2 相关软件介绍及原理分析 5 2。1 ADAMS简介 5 2。2 运动学分析原理 5 2。3 动力学分析 6 2。4 本章总结 7 3 动态模型的建立 8 3。1 轨道模型 8 3。2 人体模型 9 3。2 小车模型 9 3。3 运动副 10 3。4 载荷 (责任编辑:qin) |
