Analysis of the Traction Forces in Different Skull Traction Systems
Neurosurgery, 1988During transportation of patients under skull traction, swinging of the weights produces acceleration forces that not only can cause pain and discomfort for the patient, but also can cause worsening of the cervical fracture or dislocation. Skull traction systems also involve friction forces.

Real-Time Fault Diagnosis of Pulse Rectifier in Traction System Based on Structural Model
IEEE transactions on intelligent transportation systems (Print), 2020The pulse rectifier of a traction system in locomotives and electric multiple unit (EMUs) is usually vulnerable to performance degradation and faults due to uncertain factors, such as vibrations, aging, electromagnetic interferences.

Critical driving situations can occur not only while braking, but also whenever strong longitudinal forces should be transferred at the contact area between the tire and the ground. This is because the transferable lateral forces are reduced by this process.

Continuous Overvoltages on A.C. Traction Systems
IEEE Transactions on Power Apparatus and Systems, 1983Methods of calculating a. c. traction system overvoltages caused by harmonic distortion in the locomotive current waveforms are described. A comparison is made between the results of an analogue simulation and measurements obtained during a site test.
