Landing gear system with magnetorheological damper

The present disclosure relates to a landing gear system that may include: a sleeve coupled to a fuselage of an aircraft, such as a city aerial mobile vehicle; a steering lever, one side of which is inserted into the sleeve and the other side of which is connected to a tire; a magnetorheological (MR) damper including a cylinder coupled to the sleeve and a piston coupled to the steering rod; a sensor unit configured to measure a condition of the urban aerial vehicle; and a controller configured to control a damping force of the MR damper based on measurement data of the sensor unit. The sensor unit may include a first sensor for measuring a stroke of the MR damper and a second sensor for measuring an acceleration of the bushing. 本公开涉及一种起落架系统，其可以包括：套管，联接到诸如城市空中移动体车辆的飞行器的机身；转向杆，其一侧插入套管，另一侧连接到轮胎；磁流变(MR)减振器，包括联接到套管的气缸和联接到转向杆的活塞；传感器单元，被配置为测量城市空中移动体车辆的状况；以及控制器，被配置为基于传感器单元的测量数据控制MR减振器的阻尼力。传感器单元可以包括用于测量MR减振器的行程的第一传感器和用于测量套管的加速度的第二传感器。
