Model-based simulation: Commissioning machines in a fast and safe manner

Reducing the time-to-market: Machine manufacturers can make this dream come true with Open Core Engineering and simulation environments such as Simster by Bosch Rexroth.

Rexroth’s free multi-domain simulation platform Simster offers machine manufacturers integrated digital engineering

  • Model library for the easy creation of digital twins
  • Virtual commissioning with Hardware-in-the-Loop (HiL)
  • Shortened time-to-market thanks to the simulation of hybrid drive concepts
  • Virtual servo press as practical example on the occasion of EuroBLECH

Commissioning forming machines in a fast and safe manner – machine manufacturers can achieve this target making use of model-based simulation using Bosch Rexroth’s free and powerful Simster solution. The principle: Even before the set-up of the real machine, a virtual image is tested safely and extensively with all control structures up to and including the virtual commissioning. As a result, the programming work is reduced, the engineering quality increased and the time-to-market is shortened. The visitors of EuroBLECH will be demonstrated how easy this is using a servo press as example.

Simster is a high-performance, freely available multi-domain simulation environment developed by Bosch Rexroth themselves by means of which regulated drive systems within machine tools can be efficiently modeled and optimized. To allow for the fast creation of a digital twin, the high-performance simulation platform also offers an extensive model library from different domains, including hydraulics, mechanics and control technology. Using the Open Core Interface technology, the Simster model can be directly linked to a Rexroth control as “Hardware-in-the-Loop” (HiL). In this way, all control structures including integrated PLC programs can be reliably tested by means of the virtual image. This allows for the early optimization of design and program codes with less recursion loops. By means of Rapid Control Prototyping, the control programs can be easily created on the simulation platform using a generator. The created models can also be used for subsequent tests and modifications, e.g. in case of changed basic conditions in the production.

Bosch Rexroth will demonstrate a concrete practical example at EuroBLECH showing a press with hybrid drive concept which was created in connection with Simster and the universal modeling language. Other model-based functions such as the state monitoring and diagnosis can also be generated by means of Simster.

As multi-domain simulation environment with intuitive operating concept, Simster is similarly suitable for simulation experts and beginners. Numerous program aids and system-related explanations ensure fast senses of achievement. Integrated interfaces also allow for co-simulations with other systems, e.g. with MATLAB, Simulink and other partner solutions from the Open Core Engineering ecosystem. For the visualization of the result curves, Simster moreover provides a high-performance plotter.

Both, Simster and the Open Core Interface technology for development and simulation solutions are available for download free of charge in the Engineering Network Forum of Bosch Rexroth. If necessary, Bosch Rexroth will also provide optional support and training sessions.

Economical, precise, safe, and energy efficient: drive and control technology from Bosch Rexroth moves machines and systems of any size. The company bundles global application experience in the market segments of Mobile Applications, Machinery Applications and Engineering, and Factory Automation to develop innovative components as well as tailored system solutions and services.

No fear of the extreme: seven records using hydraulics

Force, torque, robustness: These physical advantages have always been used as arguments in favor of using hydraulics in a wide range of applications. For decades, hydraulics have amazed us time and time again by pushing the limits of what is technically possible. Below you will find seven examples of how fluid power moves huge masses safely, precisely and, if need be, quietly, how it can be used for space travel, how it works at the bottom of the ocean, how it forms steel with millimeter precision, and how it saves enormous amounts of fuel.

Simple programming and networking

According to the trade fair motto “Connected Automation i4.0 now”, Bosch Rexroth brings its powerful IndraMotion MLC to a high-performance industrial PC platform on the occasion of EuroBLECH for the first time. The control cabinet PCs of the IndraControl V series are suitable as control for hydraulic, electro-hydraulic and hybrid drive concepts. The Open Core Interface technology is also available; by means of this technology, engineering, testing and commissioning can be considerably simplified in favor of a shorter time-to-market.
