“…According to our previous research [1], it is known that the increase of horizontal vibration parameters is favorable to the normal effect of particles on the workpiece, and the pressure-sensitive film can clearly detect the perpendicular collision between particles and the film [30,31], which can therefore be used to evaluate the validity of the simulation.

“…The bidirectional composite vibratory finishing is a novel collaborative finishing technology of structure shape and surface integrity [1]. By mounting a combined fixture of axial vibration and rotation of the workpiece on a horizontally vibrating container, the relative motion of the abrasive particles along the radial, axial and circumferential directions of the workpiece can be realized, which improves the media accessibility to grooves, slits, corners, and intricate profiles of the part, especially for non-spherical particles.…”

As a novel high efficiency collaborative surface finishing technology of structure shape and surface integrity, bidirectional composite vibratory finishing (BCVF) can be applied to finish various complex components. The movement behavior of abrasive particles is closely related to the machined part performance. The flow characteristics of particles were analyzed based on the discrete element method (DEM), which reveals that the granular temperature can explain the changes in the normal and tangential cumulative contact energy on the workpiece surface. In addition, the normal contact force on the container sidewall and the pressure distribution on the workpiece surface were tested under different process parameters and the results were compared with DEM simulations. The results show that DEM model accurately predicted the particle-wall normal contact force frequency content, and the dominant frequencies are the container driving frequency and its multiplication. Meanwhile, the pressure-sensitive film can clearly and intuitively demonstrate the integrated action behavior of the particles on the workpiece surface. The overall trends of the measured pressure were comparable to the simulation results, in that the pressure increased significantly with vibration frequency and amplitude. Dimensionless vibration velocity amplitude has been verified effective in analyzing the combined effect of vibration frequency and amplitude. Therefore, it is shown that spherical particle in simulation can predict some critical properties in non-spherical processing, which provides a reference for the extended application of the BCVF process.

“…The vibration signal at the LIDAR installation location is measured in the UAV flight test site and used as an external excitation condition to design the vibration damping device. During the flight of the UAV, the wind and its own vibration factors give random excitation, and the structure will vibrate randomly under the effect of random excitation [10][11][12][13]. The statistical information of the random response mainly includes: power spectral density, correlation function, probability density, etc., where the power spectral density and the correlation function are Fourier transform pairs, i.e.…”

During the flight of a UAV, the LiDAR device undergoes random vibrations due to the changing flight attitude and wind speed conditions of the UAV. It is important to control the frequency and amplitude of the vibrations within a reasonable range by means of a damping structure. As the vibrations caused by various factors during flight are random and non-linear, this paper innovates the analysis principle and damping control means for the random vibrations of airborne optoelectronic devices. The response spectrum analysis theory is used to establish the shock response spectrum, and an optimised and improved recursive digital filtering method is used to fit the frequencies of random vibration to the synthetic shock response. Considering the uncertainty of the vibration excitation signal, a virtual excitation method is used for the first time to simulate the random vibration to which the radar may be subjected in the air, and to simplify the calculation steps. The shock plate structure is designed using a multi-point control method to innovate a passive response to the random excitation. Finally, a modal analysis of the synthesised shock response was carried out to verify that the first six modal frequencies were controlled to within 220Hz to achieve frequency reduction and the amplitudes were controlled to within 0.5mm in the three xyz directions to achieve vibration damping.
