摘要： In this work, a novel shear blade was designed using the bio-inspired design method based on the outline curves of the badger incisors. Metal shearing experiments and numerical simulation were conducted to demonstrate the improved shearing cutting performance using the novel bio-inspired shearing tool both experimentally and numerically. The experimental results indicated the metal shearing process with bio-inspired shear blade exhibited both lower vertical force and lower temperature, especially when shearing thicker metal. Finish shear surface in Blade B exhibited the longer burnish length, which indicated Blade B also obtained a better finish surface quality. This experimental observation could be attributed to that the shear cutting process using Blade B gathered a shorter duration of elastic deformation process and a longer duration of plastic deformation process. Meanwhile, the numerical simulation results showed that the Blade B has the ability in reducing temperature in deformation zone, which is more beneficial for the extension of tool life. It can thus be concluded that optimization of cutting tool geometry using the bio-inspired curves will greatly benefit the metal shearing process. This work could provide useful guidance for the performance improvement of shear cutting process using bio-inspired design of animal prototype.
