Different design of vertical auxiliary tables and flatness

       Vibration test is one of important environmental tests. A typical vibration test machine is used to conduct such a test. The major components of the vibration test machine contains vibration table attached to the shaker, control unit and sensing device for the implement of feedback control.This work will first layout the evaluation process for the analysis of vibration table and conduct both the analytical and experimental works to characterize the performance of vibration table. Section 2 mainly shows the design evaluation process and presents the performance evaluation for the initial design of the vibration table. Section 3 presents the design modification of the vibration table for several practical concerns in order to seek for a better design of table in terms of flatness performance. Section 4 shows the comparison of different designs and comes out the best one.
