A general dynamic model coupled with EFEM and DBM of rolling bearing-rotor system

•The DBM and the EFEM are coupled seamlessly to model the whole system.•A variable step numerical integration algorithm is proposed to solve the coupled model.•A hybrid bearing - spindle system and a dual rotor - bearing system are analysed. Rolling bearing – rotor systems are the key components of...
