松土齿是残膜回收机的重要工作部件之一。为此，针对以往残膜回收机松土齿易变形的情况，在 Solid-Works Simulation 中对松土齿结构进行有限元分析，找出松土齿受力时超出许用应力的区域，提出改进意见。同时，对修改后的松土齿重新进行有限元分析，结果表明：新的结构在尺寸和质量上没有大幅提高，而安全系数大大提高。采用新结构松土齿的残膜回收机在实际使用中，松土齿未见变形现象，且降低了收膜滚筒的故障率。

Ripper tooth is one of the most important working part of plastic film recycling machine , for the problem of ripper tooth easy-deformed , put ripper tooth into Solidworks Simulation and use finite element analysis , through analysis and calculating result , find out the area beyond the allowable stress when ripper tooth force , put forward improvements . Using finite element analysis again for improved ripper tooth , the new structure does not substantially increase the size and weight ,but greatly improve the safety factor .In actual use of new structure ripper tooth of plastic film recycling ma-chine,ripper tooth have no deformation , while reducing the failure rate of the recycle film drum .
