Fig. 2-2 2nd configuring phase
Hydraulically controlled drives are normally configured by the technical sales
and marketing personnel of the hydraulics supplier (e.g. Bosch, see Chapter 8
for contact address) in close co-operation with the machine manufacturer.
This configuring phase is divided into the following steps:
S
Selection of cylinder on the basis of required forces and velocities, and cylin-
der mounting conditions in the machine
(see Section 2.3.1).
S
Selection of servo solenoid valves on the basis of cylinder data, forces, ve-
locities and dynamic requirements (see Section 2.3.2, 2.3.3).
S
Selection of position measuring system, plus pressure sensors in some
cases, on the basis of measuring range, accuracy and linearity (see Section
7.1, 7.3).
S
Dimensioning of hydraulic power unit, taking all loads into account (see Sec-
tion 2.3.5).
S
Calculation of natural frequency of drive for initial assessment of whether
expected control result can be achieved (see Section 2.3.4).
S
Bosch sales personnel are assisted by the "Hydro 2" hydraulic configuration
calculation program.
The basic data required to design a system are obtained from a question-
naire.
