Ablation experiments of 5-II insulator samples were carried out using this test facility. The test cases simulated flying acceleration,which was similar to that in the chamber of rocket motor with 50g longitudinal and lateral accelerations,and vibrancy coupled condition. The vibration frequencies and acceleration amplitude were(49.3Hz,) 12g,and(48.8Hz,)(15.4g,) respectively.
A matrix equation from an inverse problem of vibration theory
The symmetric, positive semidefinite, and positive definite real solutions of the matrix equation XA=YAD from an inverse problem of vibration theory are considered.
Acetone solution-casting films of poly(methylmethacrylate) were analyzed by differential scanning calorimetry and pyrolysis gas chromatography-mass spectroscopy under natural evaporation and ultrasonic vibration, respectively.
The continuous wavelet transform (CWT) is employed to analyze vibration signals obtained from the motor body.
The results of our study indicate that when nano-SiO2, using KH-550 silane as a coupling agent, was added to UF resin by discontinuous ultrasonic vibration, its properties improved effectively.
Second recent major developments in LSWS research, as epitomized by the paradigm shifts in the prediction strategy for LSWS and the emergence of the potential vorticity perspective, testify to the theme's on-going vibrancy.
These obligations flow in part from essential rights, and also in part from what is necessary to sustain the viability and vibrancy of the community.
Argentina is known for the vibrancy and diversity of its artistic production.
All of you add or have added greatly to the richness of character and vibrancy of the department and my experience there.
But not only do our dyes add vibrancy to international fashion, they do so without placing undue burden on the environment.
Slowing of the decay rate at large vibration amplitudes and jumps in the relaxation rate at certain critical amplitudes are predicted.
And the time parameter identification process of the foundation-structure interaction system was implemented by using the data of the layer foundation-storehouse interaction system model test on the large vibration platform.
It was also clearly observed that the vibrational motion of the particle in the well became large in amplitude and the probability of the occurrence of the large vibration became large with increasing salt concentration.
This dynamic post-buckling behavior is likely to occur in 3D microstructures when they are subjected to large vibration amplitudes.
The effects of large vibration amplitudes on the stresses of thin circular functionally graded plates
A method for calculating torsional vibration when only part of the cylinders of the diesel engine are in operation has been developed. It is not only suitable for the calculation of torsional vibration when part of the different types of cylinders of various kinds of diesel engines are in operation, but also for the analysis of the characteristics of torsional vibration in the case of non-uniform cylinder load.
