Vibration analysis of a simply supported beam under moving mass based on moving finite element method

Zhuchao YE, Huaihai CHEN,

Frontiers of Mechanical Engineering 2009, Volume 4, Issue 4,   Pages 397-400 doi: 10.1007/s11465-009-0044-7

Abstract: In this paper, a moving finite element (MFE) method is proposed to perform the dynamic analysis of asimply supported beam for a moving mass (MM).The MFE method treats the moving mass as a moving part of the entire system, so that the transverse inertialeffects caused by the moving mass may easily be taken into account.

Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 10,   Pages 1678-1678 doi: 10.1631/FITEE.1500483

Abstract: 在LED灯具加速老化过程中,为获得最小截止时间,对其寿命进行快速预估,本文采用5阶滑动平均误差方法分析数据。选用同批次的16个样本,分别进行80℃和85℃应力条件下的加速老化。首先,采用e指数对光通维持率进行拟合,获得每个灯具的加速寿命,进而采用威布尔分布对加速寿命进行拟合,获得中位寿命。其次,采用平均滑动误差方法,可获取不同截止时间下中位寿命预估误差。结果表明:加速老化过程中,存在最小截止时间,该时间可通过滑动平均误差和截止时间的关系确定;当截止时间小于该值时,寿命预估不合理;寿命预估误差随截止时间增加而逐渐减小。对于该类LED灯具,80℃时最小截止时间为1104小时,寿命预估误差为1.15%;85℃时最小截止时间为936小时,寿命预估误差为1.24%。当寿命估计误差约为0.46%时,80 ℃和85 ℃对应的中位寿命分别为7310小时和4598小时。
