Reliability Assessment and Dynamic Analysis of Electronic Circuit Board and Electronic Devices of Local Control Panel Mounted on Rotating Machine Skid

摘要

Reliability of electronic devices and circuit boards of local control panel installed on rotating machinernskid is an important issue. In this paper analytical modeling of electronic circuit board (plate) installedrnin a complex package under dynamic load is addressed. It describes how dynamic behavior of platernbeing changed in interaction with system dynamic characteristics. Solutions are in agreement with experimentalrnresults which show electronic circuit board failure in machine local control panel under dynamicrnloading considerably less than values required to affect the plate when plate itself , lonely, isrnunder vibration test. It is recommended to install local control panel near machine skid on separaternskid, if not possible (installation on machine skid) careful modeling and dynamic reviews are necessaryrnto investigate resonance and dynamic overloading.
