PAGE\*MERGEFORMATIV某二级减速器箱体设计及模态数值分析摘要本文联合利用UG软件和AnsysWorkbench软件对二级减速器箱体进行模态分析。首先通过查二级减速器课程设计的相关书籍进行二级减速器的使用要求分析，其次进行了二级减速器力学分析和传动比分配，然后按照参数在UG中进行某型二级减速器箱体三维模型的参数化设计，并将设计好的模型导入AnsysWorkbench软件中进行自由模态和约束模态的分析，得出了二级减速器箱体前十阶的模态频率和阵型，了解了二级减速器箱体的阵型位移最大的区域和阵型特点。本设计将箱体的设计，建模和分析结合的一项综合性研究，对同类产品的固有特性分析和设计具有指导性意义，为二级减速器箱体振动、噪声特性分析及噪声控制提供了可靠的依据。关键词：二级减速器箱体，模态分析，数值模态，AnsysWorkbenchAbstractInthispaper,combineduseofUGsoftwareandAnsysWorkbenchsoftwaremodalanalysiswascarriedoutonthesecondarygearreducerbox.Checkfirstthroughthecurriculumdesignofthesecondaryreducerrelatedbooksforsecondaryreduceruserequirementanalysis,thesecondsecondaryreducermechanicsanalysisandthedistributionoftransmissionratio,andthenaccordingtotheparametersforacertaintypeofsecondaryreducerboxintheUG3dparametricdesignofthemodel,andtodesigngoodmodelimportinAnsysWorkbenchsoftwarefreemodalandconstraintmodalanalysis,obtainedthesecondarygearreducerboxfirsttenordermodalfrequencyandformations,understandthelargestdisplacementofthesecondarygearreducerboxformationandformationcharacteristics.Inadditionthispaperisthedesignoftheboxbody,modelingandanalysisincombinationwithacomprehensivestudy,theanalysisontheintrinsiccharacteristicsofsimilarproductsandthedesignofinstructionalsignificance,forthesecondarygearreducerboxbodyvibrationandnoisecharacteristicsanalysisandnoisecontrolprovidesareliablebasis.Keywords:secondaryreducerboxbody,themodalanalysis,thenumericalmodal,AnsysWorkbenchHYPERLINK"http://fanyi.youdao.com/translate?keyfrom=sogouse&i=%E6%9C%AC%E6%96%87%E8%81%94%E5%90%88%E5%88%A9%E7%94%A8UG%E8%BD%AF%E4%BB%B6%E5%92%8CAnsys+Workbench%E8%BD%AF%E4%BB%B6%E5%AF%B9%E4%BA%8C%E7%BA%A7%E5%87%8F%E9%80%9F%E5%99%A8%E7%AE%B1%E4%BD%93%E8%BF%9B%E8%A1%8C%E6%A8%A1%E6%80%81%E5%88%86%E6%9E%90%E3%80%82%E9%A6%96%E5%85%88%E9%80%9A%E8%BF%87%E6%9F%A5%E4%BA%8C%E7%BA%A7%E5%87%8F%E9%80%9F%E5%99%A8%E8%AF%BE%E7%A8%8B%E8%AE%BE%E8%AE%A1%E7%9A%84%E7%9B%B8%E5%85%B3%E4%B9%A6%E7%B1%8D%E8%BF%9B%E8%A1%8C%E4%BA%8C%E7%BA%A7%E5%87%8F%E9%8
