Dynamic simulation – effective use in day-to-day development

Simulation tools are widespread in everyday industrial development processes. However, they will only make a useful contribution to development tasks if used effectively. Hydrive combines a methodical approach and outstanding technical knowledge with skilled use of tools to provide its clients with customised simulation services that enable products to be developed quickly and effectively.

1,000 forage harvester tests in one night

Hydrive has set up a Hardware-in-the-Loop test bench for a forage harvester by Claas Selbstfahrende Erntemaschinen GmbH. Over 1,000 tests have been programmed so far and can now be performed automatically on each piece of new software.

Control system for a valveless wheel loader

Implementing energy-efficient drive technology in mobile machines reduces fuel consumption, cutting costs for users. To ensure acceptance, these new drive technologies must maintain the same standards of operability and machine performance that users are used to. This represents a huge challenge in terms of developing the control system, as in-depth understanding of machine behaviour and drive technology is required.

Developing and commissioning a concrete paver

The concrete paver was taken into operation after being successfully developed and commissioned with considerable help from Hydrive. It has now been in use on various construction sites for over six months.

New modelling approach for evaluating shaft seals

Large ship drive shafts are sealed using special radial shaft seals, whose operating conditions are as complex as they are varied. Hydrive Engineering has conducted a project to develop a simulation model for shaft seals, in which it laid the foundations for a more precise way of simulating the dimensions of entire sealing systems.

3D Modelling of Hexapod Manipulators

Hydrive simulates Hexapod Manipulator to create a more mature prototyp and to minimize development time.

System optimisation of an active roll stabilisation

Hydrive Engineering develops simulation models that make coordinating and optimising active stabilisers in vehicles more effective.

Simulation models speeding up the development of shock absorbers

Hydraulic valve systems can help car manufacturers and suppliers to achieve complex vehicle functions, for example variable electric shock absorbers or active roll stabilisation system. However, such complex components have to pass functional and safety tests during the development phase.

Supporting development and identifying faults using targeted equipment measuring techniques

Analysing and optimising the drive functions of equipment and plants often poses many challenges. Dynamic equipment measuring techniques can bring significant advantages for experimental investigations.

Hydrive at 15th ITI Symposium in Dresden

The 15th ITI Symposium took place in Dresden from 14th to 15th December 2012. There, Hydrive Engineering and KÖPPERN Aufbereitungstechnik reported on common, simulation based investigation for a risk analysis in their presentation “Intake Effect of Oversized Foreign Material in High Pressure Grinding Rolls”.

Hydrive Engineering develops customised valve design

Certain applications increasingly require hydraulic control systems with special functions. A wide variety of functions coupled with a compact design is usually only achievable with individually designed valves. Hydrive Engineering develops, constructs and tests innovative valve constructions which meet your needs.

Bridge hydraulics

A detailed simulation model of a lowering brake valve was developed for the analysis of the oscillatory tendency of a hydraulic bridge drive.

State theatre Dresden

The main valve stages in the low pressure water hydraulic system, which operates the three lifting platforms in the substage and is about 100 years old, had to be replaced due to heavy abrasive wear. The newly developed main valve stage with a nominal size of 100 mm led to a considerable improvement in positioning behaviour.

Hydraulic Steering system for drilling equipment

Different variants of a miniature hydraulic drive for steering drilling equipment operated underground were designed, analysed and evaluated with the help of the dynamic simulation.

Miniature axial piston pump

The effect of extreme ambient conditions on the pumping behaviour of a miniature axial piston pump operated underground were systematically analysed using dynamic simulation and checked in an experiment using a high-speed camera.

Adjustment for a piston pump

An innovative adjustment system for piston pumps for traction drive applications was tested and compared with the state of the art using dynamic simulation.

Plastic injection moulding machine

Alternative variants were tested and evaluated in the course of the development of an innovative drive concept for a plastic injection moulding machine based on rpm-regulated hydraulic pumps.

Hydraulic system for a road finishing machine

A complete hydraulic system, which met the requirements in terms of controllability, precision dosing control and energy efficiency, was developed for a road finishing machine.
