摘　　要：以3段式变距螺杆为研究对象,通过对原数学模型仿真,找到螺杆螺旋线存在干涉的原因。依据供送容器的输送方式,推导供送变距螺杆新数学模型,仿真发现新数学模型可消除供送过程中出现的"挤瓶"现象。采用实测和仿真结合的方法,通过现场测试数据和仿真提取数据比对,验证了新数学模型的正确性。By the original mathematical model simulation the three - pitch variable screw was studied, and the cause of screw he- lix interference were found. According to the feeding container transportation methods, variable pitch supplying screw new matbe- matical model was derived, then the simulation shows that the new mathematical model can eliminate the feeding process of ＂squeeze bottle＂ phenomenon. At last, using a combination of measurements and simulation methods, the correction of a new mathematical model was verified by comparison of field test data and extracting simulation data.
