【摘要】：移動制造中心為配置3D打印機的卡車,其中的熔融沉積成型(FDM)機運動狀態(tài)非常復(fù)雜,這會影響FDM成型機的成型成功率。為此,分析了FDM成型機的運動狀態(tài),主要有水平方向的加速與減速狀態(tài)、豎直方向的超重與失重狀態(tài)、水平旋轉(zhuǎn)狀態(tài)、縱向與橫向翻轉(zhuǎn)狀態(tài)、振動狀態(tài)等。用WORKBENCH軟件進行了不同運動狀態(tài)下的應(yīng)力仿真分析,分析得出,在不考慮振動時,零件與熱床的黏結(jié)面的應(yīng)力主要受水平加速運動狀態(tài)的影響,且最大應(yīng)力主要出現(xiàn)在零件與熱床黏結(jié)面的邊緣部分。在失重狀態(tài)及超重狀態(tài)下,黏結(jié)面的應(yīng)力均較小,其最大應(yīng)力主要分布在黏結(jié)面的邊緣部分。在考慮振動的運動狀態(tài)下,零件與熱床黏結(jié)面的最大主應(yīng)力及最大剪應(yīng)力顯著增大。
[Abstract]:The mobile manufacturing center is a truck equipped with 3D printer, in which the motion state of the molten deposition molding (FDM) machine is very complex, which will affect the success rate of the molding machine of the FDM. For this reason, the motion state of the FDM molding machine is analyzed, mainly with the acceleration and deceleration state in the horizontal direction, the weight loss state in the vertical direction and the horizontal rotation state. The stress simulation analysis under different motion states is carried out by WORKBENCH software. The stress of the bonding surface between the parts and the hot bed is mainly influenced by the horizontal acceleration state when the vibration is not considered, and the maximum stress occurs mainly in the edge part of the adhesive surface of the parts and the hot bed. Under the condition of weightlessness and overweight, the stress of the bonding surface is small, and the maximum stress is mainly distributed on the edge of the bonding surface. The maximum principal stress and the maximum shear stress of the adhesive surface of the parts and the hot bed are significantly increased under the vibration state of motion.
