Optimal Synthesis and Implementation of Resonant Vibratory Systems

Abstract

The problems of synthesis and substantiation of elasticity parameters of the resonant vibratory device with electromagnetic drive and one flat spring are considered. At first, the harmonic systems with oscillation frequencies of 50 Hz and 100 Hz were investigated. Then, various asymmetric piecewise linear characteristics of elasticity were carried into effect on one flat spring using auxiliary intermediary fixed cylindrical supports. Due to this, the corresponding vibro-impact operation modes were obtained. The resonant systems characterized by improved functioning efficiency were carried into effect using the new technique of optimization synthesis of elasticity parameters. The resonant systems being investigated were implemented in practice. The basic experimental investigations of their kinematic, dynamic and energetic parameters were carried out. The fundamental result of the investigation consists in confirmation of the improved dynamic efficiency of vibro-impact systems with pulsed electromagnetic excitation designed according to the new technique. The proposed systems may be used in technological processes of materials compaction and screening, of surface treatment of machine parts and in processes associated with nanotechnology.

Determination of parameters of vibro-impact machines taking into account their main characteristics

“…Тому оптимізаційну задачу доцільно базувати на моделях, що описують коливальний рух системи суміжно із джерелом збурення. Зокрема, модель, що описує коливальні процеси у вібраційному пристрої із двома коливальними масами, що приводяться в рух від електромагніту змінного струму, наближено можна подати у вигляді [10]: Визначальні залежності пришвидшення руху робочої маси, що відповідають встановленим вимогам, наведені на рис. 3.…”

Synthesizing a resonance anti-phase two-mass vibratory machine whose operation is based on the Sommerfeld effect

“…In them, vibration exciters of lower mass generate vibrations at a greater amplitude, thereby improving the energy efficiency, reliability, and durability of vibratory machine operation. The basic principles of designing such machines were considered in [1,2].…”

“…The inertial vibration exciters of a lower mass excite more intense vibrations compared to electromagnetic vibration exciters [2]. Therefore, hereafter we consider vibratory machines only with inertial vibration exciters.…”
