The Design Of Vibration Table Monitoring System Based On STM32 Microprocessor

With the higher requirements of product safety and reliability,cars,trains,aircraft and aerospace equipment must complete large numbers of vibration fatigue tests before service.Stability and reliability of vibration table,as an important test equipment of reliability measurement,were of great significance.And large-scale vibration table was directly related to the national strategic weapons and deep space exploration and other key test areas,so it also symbolized the national scientific and technological strength from a certain perspective.It was prominent study to raise the parameters of comprehensive performance of vibration table and to manufacture larger vibration shaking table in vibration industry.As a result of inertia and other factors,the vibration table center featuring large stroke and high thrust was deviated that was misalignment.With great efforts to principle statement and scheme demonstration,a set of sensors equipped with new eddy current was designed to collect data,which was a digital servo control system processed by STM32 microprocessor.The system was mainly based on the servo control system expanding the sub-system of temperature regulation of moving coil,platform of horizontal inclination measurement and system voltage and current collection.The thesis introduced in detail key part of hardware and compared several PID control algorithms.Finally improved-type and fuzzy adaptive PID control algorithm was used,which had a good regulating effect on nonlinear system circuit by verification.The system could steadily and effectively achieve immediate rectification and automatic centering.Through comparison,the performance of system parameter raised by20% so that it had great engineering application values to meet the requirements of practical engineering.
