Every working situations dynamic stress range, working frequency and inherent frequency were gotten by data analysis, the main reason of the concrete pump having larger dynamic stress and vibration impact was found by comparing with corresponding working situations results of the bump hydraulic system test.
In order to adapt to the environment of random vibration and high shock,for the leveling equipment based on 2-axis quartz accelerometer,a design method of the support structure and inherent frequency of the accelerometer which has the structure of three beam single isle and double beam single isle is introduced,and the design result is analyzed by finite element method and proved by vibration and shock examination.
On this basis, the nonlinear dynamics of the simple vibro-impact crushing system was investigated by numerical simulation method, which prvide a base for the thorough study of coupling dynamics and dynamical design of the real vibration cusher.
The response equations are derived in sinusoidal excitations and the required electromagnetic force waves are computed in order to obtain a given vibration and shock accelerations.
The design approach presented has potential use in the development of vibration and shock isolation structures, sound isolation pads/partitions, and multiple band frequency filters, among other applications.
Steady-state nonlinear motion confinement is an essentially nonlinear phenomenon with no counterpart in linear theory, and can be implemented in vibration and shock isolation designs of mechanical systems.
The problems for gamma-ray spectroscopy in this application include size limitations, elevated and/or variable temperature environment, vibration and shock, and remote operation.
Results of the work will provide a platform for the development and understanding of nanoparticle-reinforced materials that are light-weight, vibration and shock resistant.
Statistical description of the limiting set for chaotic motions of the vibro-impact system
A numerical investigation of statistical properties of chaotic motions that occur in one vibro-impact system as a result of the bifurcation connected with the arrival of the periodic motion at the boundary of infinite-impact motion domain.
