【摘要】：針對目前龍門式3D打印機打印平臺固定且打印空間受限的問題,基于圓柱坐標系用ρ、θ和z三個參數(shù)對三維空間進行描述的原理,創(chuàng)新設計出一臺具有旋轉(zhuǎn)運動、水平移動和上下移動的三自由度懸臂式3D打印機。通過對底座上方機械的結構分析和受力分析,對旋轉(zhuǎn)傳動裝置分析模型進行了簡化處理。并使用有限元軟件ANSYS Workbench對簡化后的旋轉(zhuǎn)傳動裝置進行了靜力分析和模態(tài)分析。在靜力分析和模態(tài)分析的基礎上,按輕量化的設計要求,利用ANSYS的響應曲面優(yōu)化工具,對減速器承載體的關鍵尺寸進行多目標優(yōu)化。優(yōu)化結果表明,響應面優(yōu)化法能很好地完成多目標優(yōu)化設計,實現(xiàn)了整機的輕量化。
[Abstract]:In order to solve the problem that the printing platform of gantry 3D printer is fixed and the printing space is limited, based on the principle of describing 3D space with three parameters of 蟻, theta and z in cylindrical coordinate system, a rotating motion is designed innovatively. A three-degree-of-freedom cantilever 3D printer that moves horizontally and up and down. Through the structural analysis and force analysis of the machinery above the base, the analysis model of the rotating transmission device is simplified. The static analysis and modal analysis of the simplified rotating transmission device are carried out by using the finite element software ANSYS Workbench. On the basis of static analysis and modal analysis, according to the lightweight design requirements, the key dimensions of the carrier of the reducer are optimized by using the response surface optimization tool of ANSYS. The optimization results show that the response surface optimization method can well complete the multi-objective optimization design and realize the lightweight of the whole machine.
