Abstract: To study the design rationality and operation reliability of arc-shaped film binding nail teeth, this paper studies the stress of arc-shaped film binding nail teeth in soil by theoretical analysis method and carries out modal simulation and static simulation based on Ansys finite element analysis software. Finally, a field test is provided to verify the rationality of the design after the simulation test. According to the theoretical analysis, the structural parameters of the arc-shaped film binding nail teeth and the traction force of the machine have a significant impact on the force when it moves in the soil. According to the modal analysis of the arc-shaped film binding nail teeth, the first natural frequency is 788.15 Hz. The results show that the maximum deformation is 6.705 8 mm, the maximum strain is 3.889 2×10^-3 mm/mm, and the maximum equivalent stress is 466.27 MPa. The field test results show that the average pick-up rate of residual film of the residual film recycling machine is 58.53%, and the average film removal rate is 98.14%. The design of arc film lifting nail teeth achieves the expected goal, the work meets the actual operation requirements, and the strength also meets the actual work requirements. This research can provide a basis for designing a new type of residual film recovery machine.
