High-quality data samples are essential for the early detection of bearing failures and analysis behavior. The accurate simulation fault conditions can provide valuable insights into understanding failure mechanisms. This paper establishes a new numerical method double-row cylindrical roller (DCRB) faults based on augmented Lagrange dynamics method, overcoming limitations previous models by incorporating related to cage fracture. accounts dynamic behavior rollers during motion cycle their...
A split Hopkinson pressure bar (SHPB) experiment was done to examine the feasibility and explosion resistance of high‐damping rubber materials developed for use in area antiexplosion applications. Through experiment, dynamic mechanical properties were determined. The existence compressive stress‐strain curves at various strain rates have been confirmed from SHPB experiment. variation law compression performance with rate is studied, energy absorption characteristics are analyzed. To study...
The long duration and high impulse shock wave of thermobaric bomb threatens the security underground structures. To obtain resistance blast door against wave, firstly, dynamic mechanic property damping rubber was studied by split Hopkinson pressure bar (SHPB) equipment stress-strain relationship under average strain rate 5200/s obtained. Secondly, numerical model interlayered high-damping-rubber established with ANSYS/LS-DYNA code based on test results, antiknock performance analyzed...
