Study on abnormal abrasion of metro pantograph
机车电传动, 2023 Pantograph-catenary system is the central system for the power supply of urban rail transit trains. Higher train speed and complex train operating environment can generate severe vibrations on the pantograph-catenary system, resulting in high-frequency ...

Approximate solutions of hybrid stochastic pantograph equations with Levy jumps [PDF]
, 2013 We investigate a class of stochastic pantograph differential equations with Markovian switching and Levy jumps. We prove that the approximate solutions converge to the true solutions in 퐿 2 sense as well as in probability under local Lipschitz condition ...
