Objective
The objective of this master thesis is to perform a theoretical investigation of cooling concept in hydraulic
system and optimization of cooling strategy.
Introduction
© Bosch Rexroth AG 2010
Bosch Rexroth Mellansel AB delivers complete drive solutions for industrial applications where low rotational
speed and high torque is required. Customer focus is important for Bosch Rexroth Mellansel and it is important
to help customer to reduce Total Cost of Ownership (TCO) by being more energy efficient and improving the
availability of the hydraulic system.
At present coolers for the hydraulic systems are dimensioned using thumb rules. Presently cooling systems
are designed such that the cooling strategy is designed for worst efficient operating point possible in load
cycle. At efficient working points cooling flow corresponding to the worst efficient operating point creates
wastage of energy.
Work description
This thesis work involves understanding operating principles of closed loop hydraulic dive systems. The losses
in hydraulic systems which generates heat needs to be understood. The proposed thesis involves three main
parts:
1. Develop mathematical model of heat generation and cooling of the hydraulic system and use this
theoretical understanding to develop simulation models suing simulation tools like MATLAB, AMESim
etc.
2. Investigate on different methods for cooling the hydraulic system efficiently.
3. Suggest methods to verify the simulation models.
