TURN Simulates low speed turning maneuvers of cars, buses, trucks, trailers, airplanes, user-defined vehicles... along a tracking path.

What is Turn?

Turn simulates the low speed turning maneuvers of a range of vehicles from cars through to trailers and semi-trailers, as well as user-defined vehicles, along a specified tracking path.

Why Choose Turn?

CREATE TRACK PATHS EASILY

It has been designed for ease of use. You simply draw or select the vehicle path, select the vehicle for the simulation, and then specify either a forward or a reverse run to create the track or swept path envelope.

VEHICLE LIBRARIES

Vehicle Libraries are completely user configurable. Libraries for TRH 17 design vehicles and various commercial aircraft are distributed with the program. You can create new libraries and add your own vehicles to the library by simply entering the dimensions for the new vehicle into a graphical vehicle dimension dialog.

A full range of vehicle configurations is supported. Single unit vehicles include passenger cars, buses, trucks and forklifts. Trailer and semi-trailer combinations such as cars with trailers, articulated vehicles and interlinks are also supported as well as nose-steer and tail-steer aircraft.

FORWARD AND REVERSE MOVEMENTS

Forward and reverse movement for any of the supported configurations can be simulated along a specified track path. You can generate minimum turning envelopes by simply indicating a start position and an initial direction of movement. You can then drag the entire envelope to check critical sections of intersections, traffic circles and parking areas.

OUTPUT GRAPHS

Output graphs which are displayed for every simulation can be used to determine how close the design vehicle is to any point along the path at its maximum steering angles.

CARGO POINT TRACKING FUNCTION

Additional points, within or beyond the vehicle’s body, can be tracked using the Cargo Point Tracking function. This allows you to track the position of cranes, side mirrors or cargo extremes along the track path.

DYNAMIC SIMULATION

Indicate the starting position and direction and then graphically indicate a series of way points. The vehicle will automatically move to the way points conforming to its minimum steering angles.

To finish off your drawings you can place a vehicle profile, complete with dimensions, by simply selecting a toolbar button and indicating the position of the profile graphically.

Turn has been used extensively in a number of projects to design roundabouts, intersections, parking areas, load bays and warehouses.
