TRAMotion: the best solution for envelope calculation

Overview

TRAMotion is based on a very efficient numerical engine to calculate the movement of tram/rail vehicles. It allows the automatic construction of a kinematic model of any tram vehicle and fast and accurate calculation of envelope, collisions with infrastructure and much more.

Purchasing new vehicles
In tendering procedures, the right choice of vehicle concept and its optimization are essential in order to meet the customer’s requirements. Moreover it ensures that the vehicle operates seamlessly in the given infrastructure.

TRAMotion supports the processing of basic tasks and questions such as:

• Collision-free operation with other vehicles and infrastructure (stops, poles)
• Avoidance of passing bans
• Compliance with existing track network and/or standards.
• Efficient and simple investigation of vehicle variants and their optimization
• Comparison of envelopes of in-service and new vehicles

Vehicle design
Optimization of individual vehicle parameters to ensure reliable passage while maximizing compliance with the requirements of the tender documentation, such as ideal axle pressure distribution, ideal passenger door position, ideal vehicle cross-section, cab shape, bogie rotation, etc.

TRAMotion provides options to optimize the vehicle in terms of envelope requirements such as:

• Easy modification of bogie configuration and/or vehicle concept
• Simple modification of the vehicle outline
• Comparison of the vehicle envelopes of different vehicle variants

Conversion of existing lines / planning of new lines
Rebuilding existing lines and planning new lines, stops, depots and workshops is a demanding planning activity. One of the basic requirements is to ensure the smooth operation of vehicles in interaction with the rebuilt or newly planned infrastructure.

TRAMotion supports the processing of basic documents and answering questions such as:

• Suitable construction and / or position of the new stops for existing and planned vehicles
• Recommendations for modifications to the alignment and surrounding infrastructure
• Collision-free operation with other vehicles and infrastructure (stops, poles)
• Avoidance of passing bans

• simple vehicle definition – the user can easily create any vehicle by connecting different types of modules with fixed or rotating bogies
• track & infrastructure – linear and circular segments; left and right borders relatively to track axis
• vehicle kinematics – simulates tram movement through infrastructure considering axial position and also axle offsets
• animation of vehicle movement – useful for better understanding of tramway behaviour and for presentations
• axial envelope calculation – vehicle moves along track axis, user is informed about particular point on a module outline which caused the envelope point
• worst case envelope calculation – algorithm calculates also “the worst case” position of vehicle based on track channel parameters
• bogies angles – the algorithm also calculates other geometric quantities useful in vehicle design and other analyses
• versatile input/output in Excel – vehicle structure and module dimensions can be read; calculation results are stored for further analysis or reporting
