Dynamic design theory and application of large vibrating screen
Abstract
The reliability is a key factor for the design and manufacture of large vibrating screen. In the paper, we presented a new large vibrating screen with hyperstatic net-beam structure. Dynamic characteristic of the vibrating screen was researched and dynamic
simulation method of large screening machines was explored. We used finite element method (FEM) to analyze dynamic characteristic of large vibrating screen with hyperstatic net-beam structure. Multi natural frequency, natural modes of vibration and dynamic response of the vibrating screen were calculated. The structural size of stiffeners on
摘要：
可靠性是設(shè)計和制造一個大型振動篩的關(guān)鍵因素。在論文中，我們提出了一個新的超靜定網(wǎng)梁結(jié)構(gòu)振動篩的理念。對振動篩的動態(tài)特性和動態(tài)模擬大型篩分機方法進行了研究和探討。我們用有限元法 分析大型動態(tài)超靜定網(wǎng)梁結(jié)構(gòu)振動篩的特點。對于振動篩的固有頻率、固有振動模式和動態(tài)響應(yīng)進行了計算。對于在多頻率的約束下側(cè)板上加強筋的結(jié)構(gòu)尺寸進行了優(yōu)化，并給出一個自適應(yīng)的優(yōu)化準則。結(jié)果表明，增強振動篩的結(jié)構(gòu)強度 ，其彎曲變形的固有頻率也得到了增強。模態(tài)頻率遠離工作頻率，因此，該結(jié)構(gòu)能夠有效地避免共振，并減少了破壞性。該振動篩的最...
