Calculation for selection of vibration test systems and related factors:
The existing conditions for the experiment must be given for the selection of vibration test system, calculation of parameters such as maximum exciting force, maximum displacement, maximum acceleration and highest frequency must be performed according to the formulas and evaluation implemented of the selected type. The key factors for type selection are as follows:
＊Calculation of sine exciting force:
F=（Mo+Mt+ML）a F=（Mo+Mt+ML）a
F：Exciting Force N（kgf）
F：Exciting Force N（kgf）
Mo:Weight of Armature kg
Mo:Weight of Armature kg
Weight of platform and clamping apparatus kg
ML:Weight of specimen kg
ML:Weight of specimen kg
A: Acceleration G（m/s2）
A: Acceleration G（m/s2）
（G=9.8 m/s2）
（G=9.8 m/s2）
If clamping apparatus is used for installation of specimen, weight and co-vibration frequency of the clamping apparatus should also be taken into consideration)
＊The relationship between frequency, displacement and acceleration:
A=【（2πf）2/1000】D[m/sec2] A:Acceleration m/sec2
A=【（2πf）2/1000】D[m/sec2] A: Acceleration m/sec2
V=【（2πf）/1000】D[m/sec] D: Displacement mm
V=【（2πf）/1000】D[m/sec] D: Displacement single peak value mm
F:Frequency Hz
F: Frequency Hz
By means of the above formulas, the maximum displacement and acceleration can be obtained through the calculation of key factors.
＊ The size of the platform extension should be determined according to the dimensions of package, and the strength of the platform should be able to satisfy the requirements of maximum frequency.
- The calculation of the random exciting force of vibration should be made according to the root-mean-square of Acceleration:
Fref=(（Mo+Mt+ML）aref Fref:Random force kgf
Fref=(（Mo+Mt+ML）aref Fref:Random force kgf
Aerf: root-mean-square acceleration
