Identification of noise and vibration is essential in dual-rotor systems with slightly different rotating speeds. This paper investigates the noise and vibration of a decanter centrifuge. Experimental investigations on a horizontal decanter centrifuge indicate that noise is correlated with the vibration in the Z axis. Noise can be classified as mechanical, fluid, air, or coupling noise. Increasing...
The flow properties of the start, stop, fluctuation and other unsteady flow stage are very important for high concentration slurry transportation. This text will analyse the change rule of the resistance, velocity and flow plug of high concentration slurry, as well as derive three equations for calculating the minimum driving pressure, the Average pressure loss and the stopping time under the viewpoint...
To satisfy the requirement of measuring high shock acceleration for hard target smart fuze, a double-end fixed beam structure of MEMS piezoresistive high g accelerometer is proposed. The designed sensor is based on the combination of Silicon on Insulator (SOI) solid piezoresistive material and Micro Electro Mechanical Systems (MEMS) technique. Based on the principle of the sensor, stress analysis...
The influence of the tire-road friction to the ACC controller has been analyzed. A double level Mamdani reasoning based ACC fuzzy controller has been established. The membership functions and the reasoning rules have been founded. The simulation results indicates that the ACC controller has very good character of road adaptive, and it performance very well in distance keeping and speed following.
