本文对不同坐标系中如何建立一个协调的空间变形管道的数学模型,进行了深入的探讨。对一些常用的简化假设在数学模型中的反映进行了分析。并对如何避免这些假设造成的不协调性提出建议。这样的模型在实际铺管问题中的应用,通过两个算例得到了反映。
In this paper, how to establish a coordinated mathematical model of space deformation pipeline in different coordinate systems is discussed in depth. The reflection of some common simplifying assumptions in the mathematical model is analyzed. And make suggestions on how to avoid the uncoordination caused by these assumptions. The application of such a model in the actual pipe laying problem is reflected by two examples.
