【摘要】 以某型号热压机的热压板及油缸为研究对象,运用固体力学中基于能量原理的变形体虚功理论,使用单位载荷法对热压板在油缸及加工板材共同作用下的变形进行计算。将热压板长度或宽度方向受力情况简化成悬臂梁和简支梁两种受力结构,根据热压板在由这两种结构的组合下,建立热压板在某一个截面上,其末端和油缸中点的挠度函数,利用MATLAB绘制函数图像,计算出使热压板变形量最小的油缸位置。使用ANSYS分析比较优化前后热压板变形的最大挠度,结果表明:优化布置后的油缸显著减小了对热压板的变形影响。更多还原

【Abstract】 In this thesis,taking hot plates and piston-cylinders as study objects,using unit load method,the thermal deformation of the plate with the common actions of piston-cylinders and woods were analyzed by the virtual work principle of solid mechanics. Along the longitudinal or width direction,the structure of hot plate was simplified into cantilever beam and simply supported beam and established specific location’s deflection function at a certain cross-section with the combination of the two structures. Also,using function graphs established by MATLAB,calculated the piston-cylinder’s optimum position where the plates got minimum deformation. In the end,the dissertation compared and analyzed the deformation of the optimized hot plates with the original using ANSYS. The result showed that the plate’s deformation is remarkably reduced after optimization.更多还原
