  • Red Hydraulic Elements
  • Green Translational Elements
  • Yellow Rotational Elements
  • Blue Functions 
  • Rigid Body Elements 
  • Multi-colored Elements

Modeling Examples Included

The modeling examples illustrate the use of HYSAN modeling elements and various configurations of these elements. They also demonstrate the numerical methods employed to solve models comprising complex coupled non-linear differential equations. The Model.dat files are included with the software.


The files can be opened in HYSAN, modified, and solved to enhance the understanding of the concepts discussed in the documentation. Additionally, sections of the provided examples can be extracted and incorporated into individual models, which can then be updated according to specific parameters

Assembly

Modeling the dynamic characteristics of inertia and momentum goes beyond the static load needed to move the load. A pressure load is created in the actuator to build up momentum or velocity for forward motion. The actuator also sees a pressure load trying to stop the velocity or momentum. Depending on the control and rate of change, the system can oscillate, overshoot, damp out, or become unstable.


Modeling dynamic characteristics of the loads involves the mechanical motion of the load and/or inputs. A translational motion can displace a fluid to produce pressure or hydraulic pressure on a piston to move the load. The mechanical motion can be transitional, rotational, or both. When the translational and rotational displacements are coupled, a kinematics relationship is formed. The velocity and acceleration of the connecting parts are also coupled. The velocity relationship couples the momentum, impact torques, and forces. While the acceleration couples the leverage or inertia torques and forces.


These examples cover the kinematic coupling of rotational and translational motions. The Assembly element in HYSAN provides the ability to define multiple rigid body CGs, with coupled pin constraints. You then connect key points in the Assembly with items from the diagram. The diagram references Body Points created in the Assembly.

Controls

Controls modeling is supported by using several modeling elements in HYSAN. The electrical coil or voltage input uses the first order delay of the current build-up (Inductance) and the detail of a family of curves to define the current, displacement force relationship. If that detail is not needed or required, then a simple force versus time curve can be used.


The Laplace elements can be used to construct a custom control. The Laplace element has Tools to construct Coil Resistance Inductance, first-order delay, notch filter, integrations, differentiations, and classical second-order transforms. Also, you can directly define the coefficients of the S operators to construct a special Laplace transform.


The Hydro-Mechanical model is usually developed using time-based functions. This identifies basic performance or response to command signals, and/or external load transients. The Sweep element can identify resonance open-loop characteristics. The hydro-mechanical side can then detune or identify which control algorithm to employ.

The classic Integral Control, with or without Derivative compensation, and various PID off-the-shelf systems can be placed in the loop with your system model. One can also construct a custom Laplace Feed forward and feedback control.

Hydraulic

The Hydraulic group of examples shows various uses of HYSAN’s ability to construct different Hydro-Mechanical systems. The tools and flexibility to configure, Volumes, Pistons, Masses, Springs, Area Curves, in a model is the key power of HYSAN. This can be applied to model more complex configurations of Hydro-Mechanical systems.

Methods

The model in this group cover how to model specific configurations and demonstrate the numerical methods employed to solve a model with complex coupled non-linear differential equations.


The Reference Material covers the details of the Numerical Methods used in HYSAN while the models in this group demonstrate the operation. For example, the Integration Continuous model shows the integration of continuous smooth response, while the Integration Discontinuous model covers events causing discontinuities. 

Power Source

The hydraulic model gets its power using the Hydraulic Pressure or the Hydraulic Flow element. These elements define the energy input to the hydraulic system. The input can be modeled as a fixed or static source of energy or can respond to the dynamics of the model. There are numerous ways to model the hydraulic input power source. The input can be defined by flow, pressure, or a combination of flow and pressure. 


The Hydraulic Pressure or the Hydraulic Flow element is the fundamental method to define the input of hydraulic energy to the system. Using these elements without any curve relationship defines a fixed or constant pressure or flow. Using these elements with a curve defines a variable pressure or flow.


The typical methods that are used to define the hydraulic power source are detailed in the following models. 

Training Workshops

The Training Workshops, included with the software, provide models to learn software operations and functions. These step-by-step workshops cover construction methods, options, and use Model Creation and Model Solution features. The three levels offered are Introductory, Intermediate, and Advanced.

FAQs

What is the purpose of HYSAN Software?

HYSAN offers dynamic simulation capabilities for hydraulic components and systems, enabling the prediction of time responses, stability, and performance metrics. The software generates comprehensive outputs, including transient response plots or tabulated data pertaining to pressures, flows, displacements, velocities, accelerations, forces, and other relevant quantities.

What types of systems can be analyzed using HYSAN?

HYSAN is not designed for a particular system; rather, it can model any hydraulic or mechanical system by combining the fundamental elements from the extensive HYSAN library.

What are the units of measurement in the software?

HYSAN offers three sets of traditional English units, five sets of Metric units, and Custom units. Additionally, conversions between these various sets of units are readily available.

How accurate is HYSAN?

The accuracy obtained using HYSAN is best characterized by first establishing whether the modeling elements mathematically represent the physical system and secondly, the ability to define the parameters of the model. When these conditions are met, HYSAN obtains accurate physical results. Conversely, if the modeling elements do not accurately describe the physical system, HYSAN will obtain the correct mathematical solution but poor physical answers.

Is Training available?

Three training workshops are included with the documentation. New users can progress through the models at their own pace, while experienced users can delve into more advanced topics. These workshop models cover construction methods, options, and the utilization of Model Creation and Model Solution features. The three levels offered are Introductory, Intermediate, and Advanced.

Consulting service is also offered.

What is ME&S?

ME&S stands for Maintenance, Enhancements, and Support. HYSAN software comes with the first year’s ME&S included. This includes phone and written support. Enhanced versions are sent at no additional cost. After the first year, this service is extended for an annual fee.
