Computer-aided design system for vibration-frequency density meters

The article is devoted to the description of developed automated design system for vibration-frequency density meters with a demonstration wide functionality program and interface settings. development solves problem designing meters, calculating quality factor sensitivity resonators, which provide dependence frequency self-oscillations on controlled density. lack clear methodological recommendations calibration, correction techniques different methods mounting resonator significantly limits use since tasks set require special skills, competencies both developers personnel during operation.
 algorithm software package based calculation amplitude-frequency characteristics tubular using differential equation determine frequencies forms bending vibrations resonator. implementation model makes it possible not only visualize shapes, frequency, antinodes vibration nodes any range materials, but also takes into account type fastening, numerical value support stiffness, adjust placement supports that meets operating conditions while visualizing shapes oscillations, simulate distribution along entire measurement range. computer-aided has simple interface, absence necessary installation settings product more accessible in industrial environment small enterprises.
 When subroutine solution free string, complex can be used string mechanical resonators sensors.
