【摘要】：为合理设计操作机悬挂系统的缓冲装置以减小惯性冲击的影响,针对平行连杆式锻造操作机,简化了设备模型,分析了制动工况下悬挂系统各杆件的受力状态和运动规律,并利用牛顿-欧拉法综合各杆件的动力学分析,建立了悬挂系统在制动时的动力学模型,提出了缓冲装置刚度及阻尼参数确定的思路。以300kN锻造操作机为例,在MATLAB中求解操作机悬挂系统动力学微分方程,分析了缓冲刚度、阻尼对吊杆摆角、钳杆质心运动规律的影响。结果表明,利用牛顿-欧拉法建立模型确定缓冲刚度与阻尼参数的方法是可行的与合理的,从而为平行连杆式操作机悬挂系统缓冲装置的刚度与阻尼设计提供了理论依据。
[Abstract]:In order to reasonably design the buffer device of the suspension system of the operator to reduce the influence of inertia shock, the model of the equipment is simplified for the parallel connecting rod forging operator, and the force state and the motion law of the members of the suspension system under the braking condition are analyzed. Using Newton-Euler method to synthesize the dynamic analysis of each member, the dynamic model of suspension system during braking is established, and the idea of determining the stiffness and damping parameters of buffer device is put forward. The 300kN forging operator is taken as an example. The dynamic differential equation of suspension system of operator is solved in MATLAB. The effects of buffer stiffness and damping on the swing angle of suspension rod and the motion of the center of mass of clamp rod are analyzed. It is feasible and reasonable to establish a model by Newton-Euler method to determine the parameters of cushioning stiffness and damping, thus providing a theoretical basis for the design of the stiffness and damping of the suspension system of parallel connecting rod type operators.
