Design and experimental analysis of circular saw blade for stubble-cutting Salix psammophila imitating bamboo rat incisors
摘要
Abstract
The circular saw blade is the main component for stubble-cutting operation of Salix psammophila,but it suffers from problems such as low cutting efficiency and teeth prone to wear during operation.Therefore,a mechanical analysis was conducted on the sawing process of circular saw blades,and a new biomimetic circular saw blade was designed by extracting the contour characteristic curves of the bamboo rat incisors as the bionic prototype.Subsequently,a finite element model of the circular saw blade imitating bamboo rat incisors was established,and the explicit dynamics software LS-DYNA was employed to simulate the sawing process for analyzing its mechanical performance.Meanwhile,the parametric comparison was made with the ordinary circular saw blade with folded-back teeth.The simulation results showed that the average sawing force of the circular saw blade imitating bamboo rat incisors reduced by 19.17%,among which the tangential force and radial force decreased by 16.67%and 10.68%,respectively.It also exhibited smaller fluctuations in axial force with shorter impact duration and achieved an 18.99%reduction in sawing energy consumption.The sawing test results indicated that the circular saw blade imitating bamboo rat incisors delivered superior sawing performance while reducing pressure and energy consumption on the saw teeth during the cutting process.The newly designed biomimetic circular saw blade provides a novel solution to address the problems of high energy consumption and easy wear of circular saw blades in the mechanized stubble-cutting process for Salix psammophila.关键词
