摘要
为使新型退卷机中承载接布作用的T形台最大挠度在最大载荷下小于0.5mm的标准要求,首先以T形台三维原理图为基础,利用ANSYS软件对T台结构在理想载荷下模拟仿真;通过机械结构应力应变结果图可看出T形台上板面最大应力沿中心对称面向两边逐渐变小,T形台竖板面最大应力分布在两个滑块以及竖板面与加强筋板的低端接触的点位。根据此结果,分别拟定了三种改进方案,一是竖板面前与上板面之间加一块筋板;二是竖板面后与上板面之间加两块筋板;三是前面加两块筋板,后面加一块盘板。利用ANSYS软件对这三种结构进一步仿真后,发现第三种方案可使T形台的最大挠度降为0.219mm。
In order to make the maximum disturbance of the T-shaped platform mechanical structure under the working load not exceed 0.5mm,Solidworks is used to draw the three-dimensional schematic diagram of the T-shaped platform,and the ANSYS software is used to simulate the T-shaped platform structure under theoretical load,and the stress of the mechanical structure is analyzed.Proposal 1 is proposed after the strain result diagram.Re-simulate scheme 1 and analyze the simulation results to propose schemes 2 and 3,summarize the pros and cons of schemes 2 and 3,and propose a more reasonable mechanical structure scheme 4 of the T-shaped platform.Perform simulation again to analyze the stress and strain simulation results to determine the rationality of Option 4.
