浮动活塞，是新型的级差活塞新结构。通过分析其碰撞过程、电动机的启动特性和压缩机启动压力的建立过程，可以得到适当的数学模型，为进一步研究和工程上采用浮动活塞提供理论依据。液压浮动活塞在运行时被油膜支托着，不与缸壁接触，可以减少磨损，并提高效率。
但从现有的断口看，二者均呈大应力过载断裂且浮动活塞明显受力不均。
According to the fracture surfaces, it is found that the fracture mode of the two parts is overload fracture and there is obvious stress concentration in the floating piston.
某飞机起落架缓冲柱塞在补压时发生突然断裂，同时弹出一小块浮动活塞碎片。
An undercarriage buffer plunger in an airplane suddenly fractured during the process of reinforcing pressure, and a fragment of a floating piston was thrown out.
四活塞卡钳双前盘式制动器，296毫米浮动叶轮和一个单活塞卡钳后轮盘式制动器，带来CBF快速感应制动功率。
Responsive stopping power is provided by four-piston caliper dual front disc brakes with 296mm floating rotors and a single-piston caliper rear disc brake.
