MOCVD 感应加热 1 、感应加热原理 感应加热是利用电磁感应原理把电能转化为热能。它与传统的加热设备相比具有诸多优点： ① 加热速度快，而且是非接触式加热； ② 只对导体进行加热，可以局部加热； ③ 加热效率高，节能； ④ 工件容易加热均匀，产品质量好。 由于其具有以上诸多优点，因此在工业中有着广泛的应用。它主要在机械制造工业、冶金及国防等领域用于淬火、透热、熔炼、钎焊以及烧结等。此外，随着感应加热理论和感应加热装置的不断发展，其应用领域也随之扩大，应用范围越来越广，如微波炉、电磁炉等已进人人们的日常生活。 急需要详细文章请回复邮箱。今天这网速是传不上去了，各位看官不好意思
这两天摸索了一下LMS.Virtual，总结一下，给初学者参考（以计算消声器为例进行 设置 ）。 1，建立 模型 ， 2，划分 网格 ， 3，网格检查，（1）Insert Acoustic Mesh Pre pro cessing Set，（2）Expand the Acoustic Mesh Preprocessing Set.1 feature and double-click the Grid Support.1 feature. A new dialog box will appear, select the mesh part monovolume Nodes and Elements and click the OK button.（3）Right-click the Acoustic Mesh Preprocessing Set.1 feature and select Update from the contextual menu. This will start the preprocessing. Click the Close Window button of the Computing.. dialog box once the preprocessing is over. 4，设置材料，（1）Insert Materials New Materials New Fluid Material or click the button from the Insert toolbar. （2）Insert Properties New Properties New Acoustic Fluid Property... or click the button from the Insert toolbar, to apply the air property to mesh.（3）A new dialog box will appear. Select the monovolume Nodes and Elements feature for the Application Region section. Refer newly created fluid material. Click the OK button. 5，模型最高频率，Right-click the Properties feature and select Update from the contextual menu. Now you can visualize the material maximum frequency images. Right-click the Properties.1 feature and select Generate Image from the contextual menu. The Image Generation dialog box will appear. Select Material Maximum Frequency and click the OK button. For better visualization, hide the Acoustic Mesh Preprocessing Set.1 feature. 6，边界集设置，Insert Mesh Grouping，本例设置了两个，一个进口，一个出口。 7，出口导纳设置，Insert Properties New Properties Absorbent Panel Property 8，进口声速设置，（1）Insert Boundary Conditions and Sources Boundary Condition and Source Set.（2）Insert Boundary Conditions and Sources Add an Acoustic Boundary Condition 9，设置分析类型，（1）Insert BEM Analysis Cases Acoustic Response Analysis Case.. or click the button from the Insert toolbar.（2）Select the Use an Existing One option for Boundary Condition Set section. This will activate the selection field. Select the No Panel Set option for Panel Set section. Refer the Acoustic Boundary Conditions and Sources feature in the specification tree. Click the OK button. This will insert the Acoustic Response Analysis Case feature in the specification tree. （3）Double-click the Acoustic Response Solution Set.1 feature to open the dialog for the solution parameters. In the Solution tab, select From Boundary Conditions option for the Edit Frequency Range. 10，计算，计算之前，要设置sysnoise的路径，Tools Options Acoustics menu, LMS SYSNOISE tab or on the Job tab of the Edit Solution Parameters dialog box. 之后就可以计算了，Right-click the Acoustic Response Solution Set.1 feature and select Compute/Update from the contextual menu. This will start the computation. 11， 结果 后处理 ，Right- click the Acoustic Response Solution Set.1 feature and select Generate Image from the contextual menu. The Image Generation dialog box will appear requesting you to select the different images.还有很多后处理方法。 比较了一下和sysnoise，感觉没有sysnoise那样方便地设置边界条件和后处理，也许我不太熟悉的原因。
