Product Introduction

SimHydraulics software is a modeling environment for the engineering design and simulation of hydraulic power and control systems within Simulink and MATLAB. It is based on the Physical Network approach and contains a comprehensive library of hydraulic blocks, as well as one-dimensional translational and rotational mechanical elements and utility blocks.

SimHydraulics software key features are:

• Enables modeling and simulation of hydraulic power and control systems in Simulink

• Provides intuitive and convenient description of multidomain models based on physical networks

• Includes a library of hydraulic components, such as pumps, valves, accumulators, and pipelines, that account for effects such as fluid compressibility, turbulence transition, and fluid inertia

• Provides foundation library of hydraulic building blocks, as well as fundamental mechanical and mathematical elements, to enable efficient extension and customization of models

• Provides customizable library of hydraulic fluids

SimHydraulics software employs a network approach to model building. Components in the network correspond to physical elements, such as pumps, motors, valves, etc. The lines that join the components correspond to physical connections that transmit power between components. Unlike traditional Simulink block diagrams, these connections are non-directional and do not require the user to resolve the causality of the system while building the model. SimHydraulics libraries contain more than 75 models of hydraulic and mechanical components. All the models were developed to be easily characterized by data normally available in manufacturer's catalogs or data sheets. Building a model of a system is analogous to assembling the actual physical system with off-the-shelf components. The end result is a hydraulic circuit schematic in concurrence with ISO 1219 Fluid Power Standard.

SimHydraulics limitations are:

• Explicit solvers are not currently supported. Only the following solvers are supported: ode15s, ode23t, and ode14x.

• A SimHydraulics physical network should not exist within a Simulink algebraic loop. This means that you should not directly connect an output of a PS-Simulink Converter block to an input of a Simulink-PS Converter block of the same physical network.

• Code generation is not currently supported.
