摘　　要：为了研究冷再生转子刀头的受力情况,通过搭建试验平台对刀头在不同空间安装参数下的切削力进行测试,获得了转子刀头切削动态应力、主应力方向和对应扭矩之间的关系,并从实验和仿真两个方面对刀座安装参数进行了相互验证。测试结果表明:刀座主应力方向与侧向倾角方向一致,侧向倾角7°切削效果较优;刀头在45°方向受到的扭力及应力较佳。In order to study the force condition of tool bits of rotors on cold recycling machine, a test bed was set to carry out the test of cutting force with different installation parameters. The relationship between dynamic cutting stress and direction of principal stress and related torque was obtained, and the setting parameters were verified by test and simulation. The test result shows that the principal stress of tool apron and lateral angle are in the same direction. Cutting effect is better with a lateral angle of 7°, while the tool bit bears better torque and stress at an angle of 45°.
