为了提高四足机器人仿生腿的使用性能,使其腿部结构满足高承载、轻量化要求,提出一种以连续碳纤维(CCF)为增强材料,以短切碳纤维增强尼龙为基体材料的混合增强 3D打印技术,通过样条拉伸实验对碳纤维复合材料的伸性能进行了验证.使用连续与短切碳纤维混合增强 3D打印制备四足机器人仿生腿,对四足机器人常见4 种工况进行了静力学仿真,选取两类典型工况进行载荷测试实验,可知在站立工况下承载力提升了19.05%,变形量减少了50.70%,在30°外展工况下承载力提升了3.14%,变形量减少了 43.05%,且重量减轻了 18.83%,验证了连续碳纤增强材料替代传统铝合金材料的可能性.
3D printing Technology of Quadruped Robot Bionic Leg Reinforced Carbon Fiber and Experimental Study
In order to improve the performance of the quadruped robot bionic leg and make its leg structure meet the high load-bearing and lightweight requirements,a hybrid reinforced 3D printing technology with continuous carbon fiber(CCF)as the reinforcing material and short-cut carbon fiber reinforced nylon as the matrix material is proposed,and the tensile properties of the carbon fiber composite are verified by using the sample tension.The hybrid reinforced 3D printing with continuous and short-cut carbon fibers was used to manufacture the quadruped robot bionic leg,and the static simulation was conducted for four common working conditions of the quadruped robot.The load capacity in the 30° outreach condition was increased by 3.14%and the deformation was reduced by 43.05%,and the weight was reduced by 18.83%,which verified the possibility of replacing the traditional aluminum alloy with continuous carbon fiber reinforced material.
