1.ansys热力学分析的基本过程及注意要点 1.1,对于稳态分析,一般只需要定义导热系数,它可以是恒定的,也可以是随温度变化的。 1.2,在分析过程中,不一定选择国际单位制,但是在建立几何模型及输入材料热性参数时,单位必须统一。 2.ansys中提供6种热载荷:温度(temperature),热流率(heatflow),对流(convection),热流密度(heatflux),生热率(heatgenerate),辐射率(radiation)。 2.1温度载荷 2.1.1在单个或者多个节点上施加温度载荷 mainmenu/solution/defineloads/apply/thermal/temperature/onnodes 2.1.2在所有节点上施加均匀温度载荷 mainmenu/solution/defineloads/apply/thermal/temperature/uniformtemp mainmenu/solution/defineloads/setting/uniformtemp mainmenu/solution/loadingoptions/uniformtemp 2.1.3在关键点上施加温度载荷 mainmenu/solution/defineloads/apply/thermal/temperature/onkeypoints 2.1.4在线段上施加温度载荷 mainmenu/solution/defineloads/apply/thermal/temperature/onlines 2.1.5在面上施加温度载荷 mainmenu/solution/defineloads/apply/thermal/temperature/onareas 2.2热流率载荷 2.2.1在节点上施加热流率载荷 mainmenu/solution/defineloads/apply/thermal/heatflow/onnodes 2.2.2在关键点上施加热流率载荷 2.3对流载荷(convection) 2.3.1在节点上施加对流载荷 mainmenu/solution/defineloads/apply/thermal/convection/onnodes 2.3.2在单元上施加均匀对流载荷 manimenu/solution/defineloads/apply/thermal/convection/onelements/uniform 2.3.3在单元上施加非均匀对流载荷 manimenu/solution/defineloads/apply/thermal/convection/onelements/tapered 2.3.4在线段上施加对流载荷 mainmenu/solution/defineloads/apply/thermal/convection/onlines 2.3.5在面上施加对流载荷 mainmenu/solution/defineloads/apply/thermal/convection/onareas 2.4热流密度载荷(heatflux) 2.4.1在节点上施加热流密度载荷 mainmenu/solution/defineloads/apply/thermal/heatflux/onnodes 2.4.2在单元上施加热流密度载荷 mainmenu/solution/deineloads/applythermal/heatflux/onelements 2.4.3在线段上施加热流密度载荷 mainmenu/solution/defineloads/apply/thermal/heatflux/onlines 2.4.4在面上施加热流密度载荷 mainmenu/solution/defineloads/apply/thermal/heatflux/onareas 2.5生热率载荷(heatgenerate) 2.5.1在节点上施加生热密度载荷 mainmenu/solution/defineloads/apply/thermal/heatgenerate/onnodes 2.5.2在所有节点施加均匀生热流密度载荷 mainmenu/solution/defineloads/apply/thermal/heatgenerate/uniformheatgenerate 2.5.3在线段上施加生热密度载荷 mainmenu/solution/defineloads/apply/thermal/heatgenerate/onlines 2.5.4在面上施加生热密度载荷 mainmenu/solution/defineloads/apply/thermal/heatgenerate/onareas 2
