双螺杆转子的受力分析

从双螺杆转子螺旋曲面的参数方程出发，利用空间解析几何理论将转子三维螺旋面坐标映象为对应不同压力腔的二维积分区域，在整个积分区域积分可以计算作用在双螺杆压缩机，双螺杆泵螺旋面转子上的力和力矩。本文以一种双螺杆泵的转子为例，利用本方法进行了受力分析，解析出转子受力，力矩随转子转角的变化关系。

Analysis of Compression Loads on Twin Helical Screw Rotors

Dynamic simulation is very difficult for twin helical scr ew rotor because of its complex geometry. A method is presented for computing t he forces and moments induced on the helical rotors within twin screw compressor?pump in this paper.In this work,using the analytic geometry theorem, the3D surface of each rotor to 2D integration regions can be mapped.The loads can be computed by integrating the chamber pressure over the rotor surfaces.An example using the method is given in computation of loads on a type of twin sc rew pump ro tors.
