Calculation for excitation force
1. The excitation force needed for the vibration test is calculated by multiplication of total load and max. acceleration:

1. For vibration test, there are 4 basic units: forece F(N), acceleration A (m/s2­­), velocity V(m/s) and displacement D(mmp-p).
   

F=ma	F....force (N)
	m....mass (kg)
	a.....acceleration (m/s2)

1. 
   2. mass of moving parts

if,
mass of vertical auxiliary table or slip table..................................................... m1
mass of moving coil.....................................................................................m2
mass of connection axis on environmental test chamber...................................m3
mass of fixture............................................................................................m4
mass of sample............................................................................................m5
test acceleration............................................................................................a
　then,
the excitation force needed for the test:
　　　　　　　　　F=(m1+m2+m3+m4+m5)a
