摘要:提出一種金屬橡膠減振器隨機振動有限元仿真方法,采用正交各向異性阻尼材料模擬金屬橡膠材料。相關(guān)仿真參數(shù)由金屬橡膠減振器正弦掃頻試驗確定。對金屬橡膠減振器進行正弦掃頻試驗和隨機振動試驗,利用有限元仿真軟件ANSYS Workbench對金屬橡膠減振器隨機振動進行有限元仿真模擬,并將仿真結(jié)果與試驗結(jié)果進行對比分析。研究結(jié)果表明,所提出的有限元仿真方法能夠很好地對金屬橡膠減振器隨機振動進行仿真,且計算結(jié)果具有較高精度。

Abstract:A finite element simulation method of random vibration for metal rubber damper was put forward. The orthotropic anisotropy damping material was used to simulate metal rubber, and the related simulation parameters were determined through the sine sweep experiments of the metal rubber damper. The finite element simulation of metal rubber damper random vibration was done via ANSYS Workbench. Simulation results was compared with the experimental ones. Results show that the proposed finite element simulation method can well simulate metal rubber damper random vibration and the calculation results with high accuracy.

Key words: metal rubber damper;random vibration;finite element simulation; orthotropic anisotropy damping material
