Analysis and Improvement of Vibration Resistance of a Home-made Ruggedized Computer Motherboard
In response to the stress damage problem caused by the onboard memory of a home-made ruggedized computer after vibration test,the strain and stress of the chassis structure and motherboard installation structure are analyzed by simulation software and the response values of the chassis and motherboard under random vibration and impact excitation are obtained in this paper.A theoretical verification method is proposed for the strain and stress analysis results of the motherboard.Combined with the motherboard installation structure form,corresponding improvement measures are proposed for the chassis and motherboard installation structure by comparing and analyzing the simulation results of the chassis and motherboard installation structure under different constraint conditions and the verification conclusion between simulation values and theoretical limitations.The experimental verification shows that the improved structural form has a good effect on the rigid fixation of the motherboard and thus can solve the stress damage problem of the motherboard after vibration test and improve the anti-vibration performance of the motherboard.It can be used as a design reference for the installation structure of similar equipment motherboards.
