Abstract: A hydraulic mem-inerter container device and applications thereof. The hydraulic mem-inerter container device comprises a first cylinder barrel, a first piston, and a spiral passage. The first cylinder barrel is divided by the first piston into a left cavity and a right cavity; and the spiral passage enables the left cavity and the right cavity of the first cylinder barrel to communicate, and the length of the spiral passage changes along with the change of the relative displacement of the first cylinder barrel and the first piston. The cylinder barrel and the piston serve as a first end point and a second end point that are independent and movable correspondingly. When used, the hydraulic mem-inerter container device can be connected to a system to control mechanical force. The hydraulic mem-inerter container device can serve as a regulation and control valve for an inerter and a damper.

Abstract: A generalized autocorrelation method for bearing fault feature extraction under a variable rotational speed condition includes: resampling an original vibration signal in an order domain based on instantaneous phase information by using an order tracking processing method, to greatly weaken a frequency modulation phenomenon; further weakening background noise in consideration of a correlation between a plurality of adjacent fragments by using a generalized autocorrelation method; and controlling an accumulation of periodic disturbances by considering only a correlation between several adjacent signal fragments based on that conventional noise resistant correlation (NRC) methods consider a correlation between all signal fragments and cannot eliminate influence of accumulated periodic disturbances. Compared with the conventional methods, this method overcomes the difficulties caused by mutually restricting signal features, and achieves a better effect.

Abstract: Provided is a hybrid electromagnetic suspension capable of self-powering and a control method thereof. The hybrid electromagnetic suspension includes an integrated structure of linear motor and cylinder block of equivalent hydraulic damper, a suspension spring, a connecting pipeline, a hydraulic rectifier bridge, an accumulator, a hydraulic motor and a rotary motor. The upper and lower chambers of the working cylinder, the lower chamber of working cylinder and oil storage cylinder are connected through the hydraulic rectifier bridge and the pipeline. The control has three modes including passive mode, semi-active mode and active mode. The ECU detects the road level according to the received sensor signal, and switches to the corresponding mode to control the suspension according to obtained road level, so as to obtain the optimal suspension performance under each road level. In the device of the invention, the linear motor and the equivalent hydraulic damper recover the vibration energy together in the case of good road condition; the linear motor and the equivalent hydraulic damper attenuate the suspension vibration together in the case of poor road surface, and at the same time the equivalent hydraulic damper also recovers the vibration energy, thus the self-powering can be realized.

Abstract: A continuously variable transmission with both equal-difference output and equal-ratio output includes an input mechanism, a hydraulic transmission mechanism, a planetary-gear-set convergence mechanism, an equal-difference output mechanism, an equal-ratio output mechanism, a clutch assembly, and a brake. The clutch assembly connects an output end of the input mechanism to an input end of the hydraulic transmission mechanism and the planetary-gear-set convergence mechanism and connects an output end of the hydraulic transmission mechanism to the planetary-gear-set convergence mechanism. The clutch assembly connects the planetary-gear-set convergence mechanism to the equal-difference output mechanism and the equal-ratio output mechanism. The clutch assembly connects the equal-ratio output mechanism to the equal-difference output mechanism. A continuously changing transmission ratio between the input mechanism and the equal-difference output mechanism/the equal-ratio output mechanism is provided by adjusting a displacement ratio of the hydraulic transmission mechanism and selectively controlling engagement of the clutch assembly and the brake.

Abstract: Disclosed are fault-tolerant permanent-magnet vernier cylindrical electric motors with an electromagnetic suspension and a fault-tolerant vector control method for a short circuit of two adjacent phases. The fault-tolerant permanent-magnet vernier cylindrical electric motor with an electromagnetic suspension and the fault-tolerant vector control method for a short circuit of two adjacent phases suppress motor thrust ripples caused by a fault of two adjacent phases of an electric motor. The dynamic performance and the steady-state performance thereof are consistent with those under a normal state, and the switching frequency of a voltage source inverter is constant.
