IACSIT International Journal of Engineering and Technology, Vol. 3, No. 6, December 2011 Shaker Table Design for Electronic Device Vibration Test System Waluyo Adi Siswanto, Mohd Norihan Ibrahim, Mohd Amran Madlan, and Siti Mariah Mohamad There are several types of vibration test systems. In regard Abstract—A general purpose vibration test system has been to the vibration control and the generating signals, a fuzzy developed to provide a testing platform for electronic devices. control can be used [4] or as a closed loop system [5]. The This paper presents the design of the shaker table for the vibration direction can be one axis in horizontal, vertical or platform-testing base where an electronic device will be placed inclined axis [6], and even multiple directions up to six axes and excited by the vibration exciter. Three design models are first analyzed their natural frequencies and the corresponding [7], [8]. mode shapes. The model with the lightest weight and the highest For a specific vibration test system for electronic computer first natural frequency is then selected to be manufactured. This devices with the dimensions not more than 15 cm x 15 cm selected shaker stable can be used in a frequency range of square, a vibration testing system in Vibration Laboratory service up to 2500 Hz and behaves as a rigid body when it Universiti Tun Hussein Onn Malaysia (UTHM) has been vibrates. The maximum dimension of the electronic device that
