VIBRATION AND NOISE CHARACTERISTICS OF A GEAR REDUCER UNDER DIFFERENT OPERATION CONDITIONS

Gear system is characterized by high efficiency, compact structure, and transmission ratio stability, and Boombox it has been extensively applied in various industrial equipment.This paper presents a novel preliminary estimate method for gear reducer noise radiation and vibration characteristics, and systematic researches on radiation characteristi

Abstract Understanding the effect of building morphology on the flow aloft is important to the ventilation and pollutant removal in cities.This study examines the dynamics over hypothetical urban Collections areas in isothermal conditions using wind tunnel experiments.Different configurations of rib-type and cube-type arrays are designed to model h
