File Description
Landing Flap (AVI)Landing Flap (ZIP)

Model of a Landing Flap

This model represents a landing flap mechanism of a large aircraft. It shows a typical SIMPACK modelling style where the entire system is set-up by a chain of interconnected bodies yielding a so-called kinematic tree.

Automotive

File Description
Virtual Suspension (AVI)Virtual Suspension (ZIP)

Model with Virtual Suspensions

Simple car model with look-up table joints for the suspensions. The complex, part-oriented modelling of the suspensions has been replaced by a look-up table joint, in order to increase the performance and avoid differential algebraic equations.

Requires a license of SIMPACK Automotive+ and Virtual Suspension Joint.
McPherson Suspension (AVI)McPherson Suspension (ZIP)

Model of a McPherson Suspension

The basic component of all automotive models is its suspension. This guide shows how to set-up the most classical front suspension system of a passenger car. It gives a general overview about the topology of suspension models and can be used as a base model for various suspension models. The model also demonstrates the modelling theory for multiple closed loops, and applying point to point primitive definitions.
Jump Start Spider (AVI)Jump Start Spider (AVI)

Model of a Jumping Car

This model shows the reliability and stability of the SIMPACK solver, capable of solving models with large non-linearities or even models containing serious modeling errors. The vehicle has been built-up using standard substructures and components from the SIMPACK Automotive+ database. The standard automotive database must be available in order to open this model.

General Machinery

File Description
Football (AVI)Football (ZIP)

Model of a Football in a Paraboloid

This model represents a football falling into a paraboloid. It demonstrates the capabilities of SIMPACK in the solution of 3D contact problems. There are two bodies with different 3D surfaces mapped in the model, where the ball has 6DOF in space and the paraboloid is fixed to the inertial system. The surfaces are defined by a function and saved in the model specific database. Through special moved markers (3D-Contact) on each body and via force elements, there is a damped contact realised between the bodies.
Controlled Closed Loop (AVI)Controlled Closed Loop (ZIP)

Model of Controlled Closed Loop

This model represents a controlled balancing 3 link closed loop using the co-simulation interface to MATLAB. The mechanism of the model is quite simple; containing 3 links (one of them is elastic) in a closed loop on a platform, which connects via prismatic joints and a force element (actuating element) to the inertial system. The force element is responsible for the balance of the system. Output values for the control loop, created in MATLAB, are position and velocity of one of the link joints and the platform velocity as an input for the actuator. After running the co-simulation interface (system solution), measurements will be carried out in SIMPACK and through a U-vector, the actuator element (Force on the Platform) will use the data to reach an equilibrium of the system.
Bogie (AVI)Bogie (ZIP)

Model of a Bogie

The basic component of all wheel/rail models is a bogie. This model shows, how to set-up a basic bogie structure. It gives an overview about the topology of bogie models, typical eigenvalues and should be a fundamental model for your further work. The model can be extended for use in various different applications.

Rail

File Description
Elastic Wheelset (AVI)Elastic Wheelset (ZIP)

Model of an Elastic Wheelset

This model represents a wheelset with an elastic axle. The wheelset axle was modelled with SIMBEAM. A correct handling of the loads acting at the mounting points of the wheels and the axle boxes is guaranteed by application of frequency response modes at these points.

Parameterised Wagon (AVI)Parameterised Wagon (ZIP)

Model of a Parameterised Wagon

This model represents a completely parameterised wheel/rail model using substructures for the bogies and a controlled air-spring for the secondary suspension. The sleepers are elastically connected to the track. The model uses two different substructures, which are saved in the model specific database. There is a substructure defined for the bogies and another for the controlled secondary suspension. The bogie substructure contains the wheelsets, bogieframe and the complete primary suspension. Most of the variables are defined using substitution variables, which is also summarised in a file in the model specific database.

The main model contains the bogie substructure, which has been loaded twice and extended with the secondary suspension components; including longitudinal- lateral damper, bump stops, anti-roll bar and air-spring, also from substructures. Global parameters such as wheel/rail profiles, excitations, track and elasticity of the sleepers are also defined in the main model. To help with the post-processing; in the general plot window, there are some pre-defined plots against various force element output values and also about important joint position states.

Airspring System (AVI)Airspring System (ZIP)

Model of an Airspring System

This model shows some basic example configurations of the controlled air spring system (control elements 152 and 153). You will need a SIMPACK Control, SIMPACK Automotive+ or SIMPACK Wheel/Rail license to run the model. The model contains single air springs, connected air springs, level-controlled air springs and an air spring connected to an additional volume. The coordinate system is for wheel/rail purposes with z-axis pointing downwards. All important parameters are defined by substitution variables and can easily be changed.
Equilibrium in curves (ZIP)

Model Quasi-Static Curving Analysis

Quasi-static curving analysis is a common task in railway vehicle design and can easily be performed with SIMPACK's parameter variation module. This model is a railway vehicle, pre-configured for quasi-static curving analysis. Important: Please see also the respective How-to-model.
Flexible Track (AVI)Flexible Track (ZIP)

Model of a flexible track

This model demonstrates the use of flexible track. The model shows a railway vehicle running over a flexible bridge which is supported at both ends and in the middle. The respective how-to-model guide accompanying this model is found in the 'Track Module' manual of the SIMPACK documentation in the chapter: "TRACK:11 How-To-Model Flexible Tracks". This model requires the licences SIMPACK Wheel/Rail and FEMBS.
