【摘要】 悬链线理论是真实反映悬索重力特性的理论。从索道悬链线的标准线形出发，推导并建立悬索无荷线形及拉力计算的数学模型；通过建立状态协调方程，导出有荷水平拉力与有荷挠度的关系，运用牛顿迭代的数值解法求解悬索有荷线形与拉力。 滑速是滑索设计的关键。从悬索力学理论出发，进行滑索的动力学分析，并用能量的观点分析荷载(滑行小车和乘客)在滑行过程中的做功情况，建立滑索运动的能量方程，计算出乘客在滑行过程中各等分点的瞬时速度。 在已建立滑索悬索设计数学模型的基础上，利用Visual Basic 6.0配套研制悬索设计系统。系统界面友好，易于操作，避免烦琐的人工计算过程，可以实现给定参数输入，进行滑速迭代计算、安全性与耐久性检验等，为滑索的悬索设计提供科学依据。 运用论文所提出的一整套系统理论，对江西赣州宝葫芦农庄滑索进行论证设计，其设计方案可行，技术先进、经济合理、安全适用。滑索整体工程于2003年12月完成，并通过国家质量技术监督局验收。通过现场实测，对数据进行分析，验证系统理论的正确性。更多还原

【Abstract】 Catenary theory is a theory that really shows the gravity property of suspension rope. Based on the standard curve of the catenary, the calculation formulas of non-load sketch and tension of suspension rope are deduced. By establishing state coordinate equation, the relationship between load horizon tension and load deflection is deduced, load sketch and tension of suspension rope is solved by Newton iteration numerical method.Sliding speed is key to the design of strop ropeway. Based on mechanical theory of suspension rope, with the opinion of energy, this paper analyses the condition of making work of Ioad(carriage and passenger) in the process of sliding, establishes the energetic equation of motion of strop ropeway, calculates the instantaneous speed of respective point.Based on the established mathematics models of suspension rope design, the design system of suspension rope is built up by using Visual Basic 6.0, which has friendly interface, easy to operate and voids the trivial process of manual calculation. After inputting the given parameters, the sliding speed is calculated by iteration, safety and durability are checked, it provides scientific theory proof for the suspension rope design of strop ropeway.Applying the set of system theory put forward by this paper, strop ropeway of Bao Hu Lu Village of Ganzhu in Jiangxi province is designed, its designed plan is reasonable, it has advanced technology, reasonable economy, safe practice. The whole engineering of strop ropeway has been finished by December, 2003, it has passed the test of State Bureau of Quality Technical Supervision. The theory of strop ropeway is verified correct through measuring data on the spot.更多还原
