Calculating the Effective Mass
Figure 9: Calculation of the effective mass of a unilaterally clamped piezo stack actuator without load
(left) and with additional load (right).
1.
Find the mass m of your piezo actuator in the data table (p. 41).
2.
Determine the additional load M.
3.
Calculate the effective mass m
eff
of the unloaded piezo actuator and m
eff
' of the loaded
piezo actuator with the formulas in the above figure.
6.2.3
Calculating the Maximum Operating Frequency of the Loaded Piezo
Actuator
INFORMATION
In the following calculation, the maximum permissible operating temperature of the piezo
actuator is
not
taken into account. During operation without cooling, the maximum operating
temperature may already be exceeded when the operating frequency is still below the limit
value calculated in the following.
For the maximum permissible operating frequency without cooling, see column B of the
table in "Maximum Ratings" (p. 43).
