【摘要】 振动试验是产品定型前必不可少的环境试验项目,而夹具是关乎振动试验成败的关键因素,为确保夹具在试验频段上不出现共振,在进行振动试验前应对其进行模态分析。本文以一种典型夹具为例,分别用有限元法和试验法对其进行模态分析,并以试验结果来确定有限元分析的准确性及评判其是否满足试验的要求。更多还原

【Abstract】 The vibration test is essential before the product type environment pilot project,and the fixture is the key factor related to the success of the vibration test.To ensure that the fixture should not resonate in the test frequency range.During the vibration test should be carried out modal analysis.In this paper,I’ll take a typical fixture for example to illustrate how to produce modal test analysis.Test analysis is used to verify whether the result of finite element analysis is exact,and the fixture satisfies the demand of vibration test.更多还原
