摘要

In response to the issues of high cutting force and energy consumption during ramie harvesting due to the strong toughness of ramie fibers, research on optimizing the structural parameters of the cutter has been conducted. In order to analyze the variation in cutting force and energy consumption during the operation of the reciprocating double-action cutter for ramie, a finite element model of the ramie-cutter cutting simulations system was established using ANSYS/LS-DYNA software for numerical simulation. The study analyzed the patterns of cutting force and ramie stalk deformation under different structural parameters of the cutter during the cutting process. A three-factor, three-level Box-Behnken simulation experiment was conducted with the cutting angle, blade angle, and cutter thickness were selected as experimental factors, the maximum cutting force and cutting energy consumption as evaluation indicators. The structural parameter combination of the reciprocating double-action cutter for ramie was optimized and validated through bench tests. The results showed that the optimal effect was achieved with a cutting angle of 24.0°, a blade angle of 23°, and a cutter thickness of 2.5 mm. Under these parameters, the measured average maximum cutting force was 163.44 N, and the cutting energy consumption was 1.49 J. The relative errors compared to the simulated theoretical predictions were less than 10%. The findings of this study can provide a reference for the design and optimization of structural parameters in reciprocating double-action cutter for ramie harvesting.
