【摘要】 为了研究扶蔗机构的工作性能,优化扶蔗器结构参数设计,建立了运动学模型。使用Solid Works,设计两段圆锥式螺旋扶蔗机构虚拟样机,应用ADAMS仿真工具,进行了运动学及力学仿真试验及高速摄影试验验证。结果表明:输送段安装角为30°~60°范围内,甘蔗不跌落;输送段安装角为60°,甘蔗扶起到最高点为4.1s,效率最高;螺旋倾角为45°时,甘蔗均匀受到螺旋叶片的作用力,无跌落现象;螺距有效范围为270~290mm,螺距为285mm时,受力情况以及扶起变化最稳定,扶起效果最好。更多还原

【Abstract】 In order to study the working performance of sugarcane support mechanism and optimize the structural parameter design of cane support device,a kinematics model was established. By using SOLIDWORKS,a virtual prototype of two-stage conical screw cane support mechanism was designed. The kinematics and mechanics simulation tests were carried out by using ADAMS simulation tool,and the high-speed photography test was also carried out. The results show that sugarcane does not fall in the range of 30 °-60 °,in which the angle of installation is 60 °,the highest point of cane is 4. 1 seconds,and the efficiency is the highest,and when the angle of helical inclination is 45 °,the sugarcane is subjected to the force of spiral blade evenly. The effective range of pitch is 270 mm-290 mm,and when the pitch is285 mm,the stress and lift are the most stable,and the lifting effect is the best.更多还原
