Stability analysis of pantograph under frictional force

Nihon Kikai Gakkai ronbunshu, 2019
The frictional force acts to the travelling pantograph head in horizontal direction due to sliding of the pantograph head and contact wire. Therefore, vertical motion of the pantograph head is generated by link mechanism of the pantograph.
