Diverter valve integrated with waterway switch, waterway control method and cleaning waterway

The invention discloses a diverter valve integrated with a waterway switch, a waterway control method and a cleaning waterway. The diverter valve comprises a valve element, a valve seat and a rotary driving part, a plurality of water outlets communicated with water use channels are formed in the end face, making contact with the valve element, of the valve seat, water passing holes communicated with a water inlet are formed in the end face, making contact with the valve seat, of the valve element, and the rotary driving part drives the valve element to rotate relative to the valve seat; and the water outlets and the water passing holes are distributed in a circular ring with the relative rotation center as the circle center, a blocking piece used for blocking the water inlet when the valve element rotates to the set position where the water passing holes and the water outlets are not communicated is further included, and the blocking piece and the valve element rotate synchronously. The diverter valve has the advantages of being simple in structure, flexible and convenient to adjust, integrated in function and the like; the waterway control method has the advantages of being high in adjusting sensitivity, eliminating the delay phenomenon, optimizing the use feeling of a user and the like; and the cleaning waterway has the advantages of being high in stability, obvious in cost optimization and the like.

Control method for multi-power source powertrain for vehicle

The invention discloses a control method of a multi-power source power assembly for a vehicle. The power requirement of the whole vehicle is decomposed into five levels of control such as working condition, mode, gear, power distribution and power source. Firstly, the vehicle operating data such as whole vehicle speed, the electrical charge state of a power battery, the state of an accelerator pedal and the time rate of change thereof, the state of a brake pedal and the time rate of change thereof are collected in real time through a power assembly controller when an electric vehicle runs; then, the power assembly controller realizes the power distribution and control for each power source of the power assembly through the five levels in sequence; the first to fourth levels of control in the five levels of control are used for selecting corresponding optimal working points according to stored data respectively, complicated calculation is not needed, the calculated amount of the control method is greatly reduced, the delay phenomenon caused by complicated mathematical formula calculation is eliminated, the requirement of a hardware system is greatly reduced, the cost of the hardware system is reduced, and the energy utilization rate of the whole vehicle is greatly improved.

Calculation Method of Correlation Coefficient of Aeroengine Load Spectrum Based on Rainflow Counting Cycle

The invention discloses an aero-engine load spectrum correlation coefficient calculating method based on rain flow counting circulation. Load spectrums of all parameters on different flight profiles are counted based on a rain flow counting method; after load circulation with the amplitude smaller than the amplitude threshold is filtered out, the circulation numbers of all the parameters of all the profiles are obtained, the different circulation numbers are obtained for different parameter load spectrums on the same flight profile, the circulation numbers, counted on all the profiles, of different parameters correspond one to one, a series of circulation data can be obtained for each load parameter, and then a correlation coefficient between all the parameters of the load spectrums are calculated. The delay phenomenon between rotation speed and overload value of an engine is eliminated, and the result more conforms to the reality. The correlation coefficient between the normal overload value representing maneuvering circulation and the rotation speed representing pneumatic circulation is close to 1 to a large extent. A basis is further provided for prediction and evaluation of aero-engine service life.
