Dynamic analysis of vibration casting equipment

Abstract

In the casting process of thermosetting explosives, mixing slurry usually appears particulate matter stack and substances uneven contact, which may result in porosity and shrinkage defects in the products. To solve this problem, vibratory technique was introduced to the casting equipment. Based on mechanical vibration theory, the motion characteristics of the vibration casting equipment in single degree freedom vibration were obtained. Through ADAMS software, the equipment's motion characteristics were simulated and analyzed. Additionally vibration displacement amplitudes in vertical direction of the vibrating object (including vertical vibration, tilt vibration and rocking vibration) under conditions of vibration state at different exciting force's frequencies and amplitudes have been acquired, which were very close to theoretical results of the single degree freedom force at different frequencies and amplitudes.
