| 摘 要： | 介绍了基于任意密封线的双螺杆压缩机的转子轮廓的设计方法.该密封线可分为几个功能段.分别控制转子高压侧和低压侧的性能,每个功能段均用三次样条曲线来拟合,通过移动样条曲线上的控制点来调整该段形状.基于密封线的这种形状,压缩机的性能就可以直接计算出来,相应的无欠切转子轮廓也就可得到了.最后,用一兼顾转子轮廓几何约束的例子来证实本方法在参数化研究上具有一定的适应性和稳定性.

| Abstract: | A design method for the rotor profile of twin-screw compressor from an arbitrary sealing line is presented.This sealing line is divided into several functional segments that control the performances of the high-pressure side and the low-pressure side separately.Each functional segment is fitted by cubic spline and the shape of the segment can be adjusted by moving the control points of the cubic spline.Based on the shape of the sealing line,the performance of the compressor can be directly calculated and th... |
