TEST DIAGNOSIS AND NOISE REDUCTION RECTIFICATION OF ACCELERATING VEHICLE INTERIOR BOOMING NOISE OF A PASSENGER CAR by LIU Gang, WANG ShengBo, ZANG ZeNan, YANG Yi

“…Aiming at the roaring noise in the accelerating car of a passenger car, the corresponding troubleshooting methods for different paths when the roaring sound is diagnosed based on the transmission path are introduced; and after determining that the problem comes from the structural transmission path of the intake system, further analysis: There is a mode with a corresponding frequency at the intercooler bracket, so the engine excitation is amplified here, and coupled with the body acoustic cavity mode, and finally forms the roar of the car; furthermore, it is clear that the intercooler installation bracket structure and the The optimized plan for cooling vibration isolation is to improve the mode of the intercooler support, improve the vibration isolation effect, reduce energy transfer, eliminate modal coupling, and solve the problem. …”

Model for Calculating Seismic Wave Spectrum Excited by Explosive Source by Qian Xu, Zhong-Qi Wang

“…The model for calculating the seismic wave spectrum excited by explosive source was acquired by taking the seismic source model of spherical cavity as the basis. The results of using this model show that the main frequency and the bandwidth of the seismic waves caused by the explosion are influenced by the initial detonation pressure, the adiabatic expansion of the explosive, and the geotechnical parameters, which increase with the reduction of initial detonation pressure and the increase of the adiabatic expansion. …”

Evaluation of Acidity Constants and Evolution of Electronic Features of Phenol Derivatives in Different Compositions of Methanol/Water Mixture by Mahmood Sanchooli

“…It was seen that the dipole-dipole interactions increase as the amount of methanol increases in solvent mixture, which implies the contribution of highly negative oxygens of methanol on hydrogen bondings between solute and solvent cavity. The orbital energies are a major electronic descriptor on solvation processes. …”

Experimental Studies on Post-Explosion Lesions in a Model of Human Soft Tissues by Anna SMĘDRA, Adrian SIADKOWSKI, Jarosław BERENT

“…The tests performed allow to conclude that a shock wave affects the surface of the ballistic soap block, generating hemispherical craters, which begin to overlap when the distance between the explosive charge and block is reduced, until they form one semi-cylindrical hollow (when linear charge is used), which represents a temporary cavity. The results obtained allow for an assessment of the extent of post-explosion lesions.…”
