摘要: 高過載沖擊試驗成本高、周期長,同時失效檢測手段較少,難以定位結構薄弱點。針對體硅工藝MEMS(Micro-electromechanical System)射頻微系統,采用沖擊響應譜與瞬態動力學方法,研究板級與試驗條件下的高沖擊載荷響應。仿真結果表明,該射頻微系統能夠承受高沖擊過載,仿真結果可提前預判結構失效點,提高產品抗沖擊可靠性。

Abstract: The high overload impact test is costly and time consuming, and the failure detection means are few, so it is difficult to locate the weak points of the structure. In this paper the impact response spectrum and transient dynamics method are used to study the impact load response of a RF microsystem based on bulk silicon micro-electromechanical system(MEMS) at plate level and under experimental conditions. The simulation results show that the RF microsystem can bear a high impact load,which can predict the structural failure point so as to improve the impact reliability of product.
Key words : bulk silicon MEMS;RF microsystem;impact;response spectrum;transient dynamics;reliability
