滑索张紧力的抛物线计算方法

Method of Parabola Calculation for Tension of Inertia Ropeway

滑索是游乐设施 ,属特种设备。它直接涉及到人的生命安全。滑索张紧力的正确计算是确保滑索安全运行的关键因素。笔者从悬链线标准线形出发 ,在抛物线曲线方程基础上 ,推导了滑索在无载荷和有载荷时滑索最大张紧力计算公式及索线长度 ,并给出了工程应用实例 ,所得结论和公式具有一定的工程应用价值 ,希望能够为滑索的设计和制造提供正确思路。

Inertia ropeway is an amusement ride. It directly concerns the safety of passengers' life. Correct calculation of the tension is the key of safety exercise for inertia ropeway. According to state of inertia ropeway development, based on the standard curve of the catenary, the force calculation and the length of suspension in the condition of parabola equation are given through the strict derivation using mathematical and mechanical method and exemplified by a real application case. Results obtained and the equation derived have some practical value in engineering, which could provide scientific criteria for the design and manufacture of inertia ropeway.
