What is DSHplus?

DSHplus is a simulation program especially developed for the dynamic nonlinear calculation of complex hydraulic and pneumatic systems and components. Its models also comprise 1D mechanical structures and controller elements of the mechatronic system. DSHplus is applicable for analysis of system dynamics, system revision, component selection, component development, fault diagnosis, as well as training purposes. It is a graphic oriented program and focuses in the description of the system on the function unit component part as the central element of the modeling conception. The resulting circuit analogy, aligned to ISO 1219, allows an easy and comfortable design of the simulation model and guarantees that the user feels immediately familiar with the simulation tool.

DSHplus comes with a collection of tools, that supports the design engineers work from the first conception of a fluid power drive to the controller design, and finally up to the start-up of the system. The result is a system design optimally adjusted to the technical problem. For the user this results into a reduction of the prototype expenditure and to a significant saving of development time.
