四方车辆研究所从1978年开始研制螺杆压缩机,已成功地用于车辆空调系统多年。当时为加工螺杆,委托西安交通大学进行螺杆与刀具型线计算。计算原理与方法,见朱国怀等所著《螺杆式压缩机型及等距型面盘型铣刀计算》。1985年,我所应用朱文所介绍的原理与方法,用FORTRAN77语言编写 Sifang Vehicle Research Institute has been developing screw compressors since 1978 and has been successfully used in vehicle air-conditioning systems for many years. At that time for the processing of screws, commissioned by Xi’an Jiaotong University, screw and tool line calculation. Calculation principles and methods, see Zhu Guohuai and other articles by “screw compressor and isometric disc cutter.” In 1985, I applied Zhu Wen introduced the principles and methods, written in FORTRAN77 language
