“…In addition to the magnetic dampers as common equipment for utilizing magnetic fluids, there are other applications to use them. The other applications of MR fluid in various industries consist of building industry (He et al, 2017;Heo et al, 2017;Xu et al, 2017;Yanik and Aldemir, 2019;Zafarani and Halabian, 2018), polishing machine (Barman and Das, 2018;Grover and Singh, 2018;Kansal et al, 2018;Khatri et al, 2017;Mosavat and Rahimi, 2019;Zhang et al, 2018), MR elastomers (Agirre-Olabide and Elejabarrieta, 2018;Bastola and Lia, 2018;Bica et al, 2019;Vemuluri et al, 2018;Yao et al, 2018), and brake manufacturing (Attia et al, 2017;Dai et al, 2019;Kalikate et al, 2018;Kumbhar et al, 2015;Topcu et al, 2018). By the development of micro-machines, a new application of this semi-active equipment emerged (Liu et al, 2016), such as the bonding pressure of the microelectronics packaging instrument that requires a constant loading force of 5 N (Li et al, 2016) and in a flip chip solder which is necessary to load an electronic chip with a damping force of less than 10 N via a power control system with a maximum error of 1%; so, it is necessary to design and optimize MR damper which obtains damping force less than 10 N for slower landing (Li et al, 2014).…”
