Correlation between the accuracy of a SHPB test and the stress uniformity based on numerical experiments
H Meng,Qingming Li +1 more
TL;DR: In this paper, two coefficients are introduced to measure the stress uniformity in axial and radial directions of the specimen in a numerical split Hopkinson pressure bar (SHPB) test.
Journal ArticleDOI
Attenuation or enhancement - A one-dimensional analysis on shock transmission in the solid phase of a cellular material
Qingming Li,H Meng +1 more
TL;DR: In this article, the characteristics of compressive shock wave propagation in the solid phase of a cellular material were studied using a one-dimensional mass-spring model, which leads to several interesting observations on the characteristic of one dimensional stress wave transmission.
Journal ArticleDOI
An SHPB set-up with reduced time-shift and pressure bar length
H Meng,Qingming Li +1 more
TL;DR: In this paper, a modification of split Hopkinson pressure bar (SHPB) set-up based on wave separation technique is proposed, which may be used to reduce the time-shifting distance and the pressure bar length in an SHPB test.
Journal ArticleDOI
Shock analysis of a head actuator assembly subjected to half-sine acceleration pulses
Dongwei Shu,Bao-Jun Shi,H Meng,Fook Fah Yap,Dazhi Jiang,Quock Ng,Razman Zambri,Joseph HengTung Lau,Chao-Shan Cheng +8 more
TL;DR: In this paper, the authors investigated the influence of pulse width/duration and pulse amplitude on the shock response of the relative displacement of the actuator arm and found that the peak relative displacement occurs at a critical frequency ratio (i. e. β = ω / ω n ≈ 0.6 ).
Journal ArticleDOI
Drop test simulation and power spectrum analysis of a head actuator assembly in a hard disk drive
TL;DR: In this paper, a simplified beam model with a torsional spring and a translational spring located at the end of the actuator arm was developed to analyze the effects of the pivot bearing stiffness on the dynamic response of the arm in a drop test.
