The reasonable establishment of rotor dynamics model is very important in the study. This paper establishes a dynamic model of the rotor, and gets the numerical calculation of the frequencies and mode shapes of the rotor under the free condition. The modal of the rotor bearing system is analyzed by using software. Compared to the above two kinds of results, the test of turbocharger rotor mechanics...
The compliant parallel guiding mechanism is widely used in the micro-driving and precision measurement. In order to analyze the output displacement characteristics of compliant parallel guiding beam, a half beam model was established based on the force analysis and deformation analysis of the supporting arm according to the symmetrical structure. And the guiding displacement and coupled displacement...
The high pressure water jet nozzle is a key part to accelerating abrasive particles. The geometrical model of fluid control volume in front and back nozzle and physical model of particle were established by object oriented fluid flow flied and particle of submerged jet. The results showed that the outlet average velocity of fluid and particle falls down sharply with the particle concentration increasing...
The relationship between force and deformation in machining was studied, taking the flexible interlayer as object. Firstly, the factors influencing the deformation in machining the flexible materials and the uncertainty of deformation were analyzed, then the force analysis of the flexible materials in machining, and the simplified linear elastic mechanical structure model of the flexible interlayer...
The authors have developed a new type of active engine mount. The active engine mount is consisted of an electromagnetic actuator and an inertia-modulator hydraulic mount. The decoupler's motion is controlled by the dynamic force generated by the electromagnetic actuator .The pressure in the upper chamber is variational, as a result the total output force from the mount to the chassis is controlled...
Wheeled mobile robots are increasingly being utilized in unknown and dangerous situations such as planetary surface exploration. Based on force analysis of the differential joints and force analysis between the wheels and the ground, this paper established the quasi-static mathematical model of the 6-wheel mobile system of planetary exploration rover with rocker-bogie structure. Considering the constraint...
The nonlinear relation between the load and the force of sensor in soft-sensing of tower crane load is indicated by force analysis of load limiter. This paper proposes a soft-sensing model based on functional link neural network (FLNN) with the force of sensor as input and the load as output. By adding some high-order terms, the model applies the single-layer network to realize the network supervised...
The neural networks identification model is developed on the basis of the force analysis of magnetic bearing spindle, which reflects the nonlinear delay character between inputs and outputs system. This network is able to converge quickly in 5 training steps. The mean square error value reduces to 3.495e-006 in 50 steps. Inspection shows that the neural networks DTNN identification model can fit the...
In order to understand the flexibility of the combined power plant in the mode switching process, this paper studied the dynamic parameters of the synchro-self-shifting (S. S. S.) clutch, a key power transfer unit for the plant. We built the mathematical model of force analysis for the parts of the S.S.S. clutch. By simulation on the mathematical model and experiment on the built flat form about the...
Fatal traffic accidents are related with the overlength braking distance and sideslip when the automobile is braked in an emergency. It is very important to study and improve the braking ability of the automobile. The anti-lock braking system (ABS) is the active method of increasing the braking ability. The ABS controller is the key to ABS. The modeling and simulation of the automobile braking system...
This paper analyses the force of the landing gear during the process of taking off and landing of the aircraft on six-DOF platform, and simulates the running of the system. Most studies of the landing gear models are based on the steady ground. In this paper, the model supports for anomaly. Applying dynamics basic theory and considering the impact of various parameters as much as possible, it establishes...
