基于Adams软件建立了剥皮机主轴传动系统的多刚体动力学模型,利用ANSYS对剥皮机主轴传动系统的关键部件进行柔性化处理,构建主轴传动系统刚柔耦合模型。通过仿真的主轴传动系统各级齿轮的转速以及对齿轮接触力参数的设置,模拟主轴传动系统的齿轮啮合过程,验证了齿轮的传动比,确定了加速度波动主要按激振频率波动,同时,主动齿轮-传动齿轮和传动齿轮-主轴齿轮的切向力和径向力仿真值分别为3 649.21 N、1 580.15 N和3 598.64 N、1 415.13 N,与理论值具有较好的吻合度,并通过齿轮啮合频率验证仿真的可靠性。最后,提取了仿真过程中3个柔性零件等效应力最大的10个节点,结果均低于齿轮材料的许用应力,从而在实际应用方面可为高性能剥皮机主轴传动系统的设计与制造提供理论参考依据。

Based on Adams software,a multi-rigid-body dynamics model of the spindle transmission sys tem of the peeling machine is established.The key components of the spindle transmission system of the peeler are flexibly processed by ANSYS,and the rigid-flexible coupling model of the spindle transmission system is constructed.The gear engagement process of the spindle transmission system is simulated by simulating the ro tating speed of the gears at all levels of the spindle transmission system and setting the contact force parameters of the gears.The transmission ratio of the gears is verified.It is determined that the acceleration fluctuation mainly depends on the excitation frequency.At the same time,the tangential direction of the driving gear-trans mission gear and the transmission gear-spindle gear is determined.The simulation values of force and radial force are 3 649.21 N,1 580.15 N,3 598.64 N and 1 415.13 N,respectively,which are in good agreement with the theoretical values,and the reliability of the simulation is verified by gear meshing frequency.Finally,10 nodes with the maximum equivalent stress of three flexible parts in the simulation process are extracted,and the results are lower than the allowable stress of gear material,which can provide theoretical reference for the design and manufacture of the spindle drive system of high-performance peeler in practical application.
