基于SolidWorks的破茬开沟犁刀的设计与强度分析
Design and Strength Analysis of Driving Colter Based on SolidWorks
摘要
Abstract
Break crop device is the key to no-tillage seeder working parts, directly affecting the quality of sowing machine. Currently, based on the domestic used break crop, a new kind of driving colter is designed. To study the strength property and reduce trouble in work, a threedimensional model on driving colter is created, using FEM analysis on driving colter with Cosmos. The distortion and stress of driving colter in service load are obtained, and the weak links are found. The maximum stress is 5. 862 × 108N/m2 and the maximum offset is 2. 648 mm. The driving colter is modified based on Cosmos. Results show that the strength and rigidity are increased, and the optimization design provides reference basis.关键词
