Engineers at UST, Inc. have tested deformation tubes that are used in a string emergency towing system. We are telling you the main points of this inspection.
What is an emergency towing device?
The emergency towing device is a subsystem of the string transport that allows to evacuate broken vehicles. Towing takes place with the help of other models that are also on the line. The most important part of this system is the deformation pipe.

Why is a deformation pipe needed?
The deformation tube slows transport speed and absorbs energy in the event of a collision. During an impact, this part can crumple (hence the name is a deformation pipe) to protect the vehicle structure, passengers and loads from damage.
But such emergencies are extremely unlikely. String vehicles are protected from collisions by intelligent vision systems that can recognise obstacles. Nevertheless, engineers have to anticipate all scenarios to ensure the safety of the travellers.
How were the tests undergoing?
Testing was carried out on several pipe variants with different wall thicknesses. The samples were placed one at a time in a special machine which loaded them at a certain speed and pressure. Tests continued until one of the pipes confirmed the geometric parameters laid down by the designers.

Where will the deformation pipe be used?
The deformation tube will be part of the emergency towing device in the Unibus U4-212-01, which is currently under development. The new vehicle model will have a capacity of up to 25 people and is designed for urban and suburban routes with a speed of up to 150 km/h.
