液压联合冲剪机剪切机构的建模与仿真

The hydraulic combined punching & shearing machine's shearing mechanism modeling and simulation

为满足各种不同的剪切需求,液压联合冲剪机经常要改变剪切机构的尺寸,以至改变机床床身的结构尺寸。对液压联合冲剪机剪切机构进行运动分析,建立剪切机构结构尺寸与运动参数之间的数学模型,通过求解非线性方程,实现对剪切机构运动的动态仿真。以Q35Y-20液压联合冲剪机为例,通过计算实现剪切机构运动的动态仿真,并可即时显示剪切机构结构尺寸与运动参数之间的关系,在任一时刻,都可对剪切机构结构参数进行修改,使剪切机构执行按修改后的参数继续运动,仿真过程通过比较优选,直至得到一组最优解。对液压联合冲剪机的关键部位进行研究,不但实现了参数化设计,还有效提高了设计的可靠性与设计效率。

For meeting all kinds of demand, the hydraulic combined punching ＆ sheafing machine often has to change the size of sheafing mechanism, even change the dimension of the lathe bed. Analyze the movement of sheafing mechanism of the hydraulic combined punching ＆ sheafing machine, establish its mathematical model between size and motion parameters. Through the solution nonlinear equation, realize the dynamic simulation of sheafing mechanism movement. Take the Q35Y-20 hydraulic combined punching ＆ sheafing machine as the example, through the computation to realize sheafing mechanism movement dynamic simulation, and may demonstrate the relations between sheafing mechanism sizes and movement parameters immediately. We can change the design parameters of the shearing mechanism at any time, and this cause the sheafing mechanism execute the revision parameter to continuative move. Through comparison optimization, the simulation process will execute until it obtain a group of optimal solutions. Study the key parts of the hydraulic combined punching ＆ sheafing machine not only realize the parametric design, but also enhance the design reliability and efficiency.
