摘要随着物质文化的日益增长，人们对于精神文明生活的追求也越来越高。过山车作为游乐设施之最，它以高速，多运动形式且极具刺激感而被大众所喜欢。为了能够更好的设计过山车类游乐设施，本文介绍通过联合仿真的方法建立双车五环过山车及其轨道模型。基于SolidWorks和ADAMS环境对五环过山车小车进行建模，建立虚拟轨道对其进行运动学仿真；基于Pro/E和HyperMesh环境建立五环过山车轨道实体模型。通过过山车动力学与应力学仿真获得过山车运动在各个工况时轨道受力所达到的最大值及其时间和位置，并利用Ansys对轨道进行有限元分析得出判断轨道各个工况的结构强度和刚度是否符合要求。87569

Title  Stress analysis on the track and column structure of two ring roller coaster

Abstract With the increasing of material culture, people's pursuit of spiritual civilization is becoming more and more high。 Roller coaster ride as the most recreational facilities, it is high speed, multi sport form and a great sense of stimulation and was loved by the majority of the people。 In order to better design the ride bikes recreation facilities。 This paper introduces double car ring roller coaster and orbit model is established through the co simulation method。 Based on the SolidWorks and ADAMS environment, the model of the ring roller coaster is built, and the simulation of the virtual track is built。 Based on the environment of Pro/E and HyperMesh, the solid model of the ring roller coaster is built。 Through roller coaster dynamics and mechanics simulation of roller coaster movement orbit in different conditions by force to achieve the maximum value and the time and location, and use ANSYS to track for the finite element analysis results to determine each track conditions of structural strength and stiffness are in compliance with the requirements。源-于,优~尔^论=文.网www.youerw.com 原文+QQ7520~18766
