2results about How to "Meet the simulation requirements" patented technology

The utility model belongs to the field of acupuncture practice devices, and particularly relates to a device for acupuncture clinical practice. The device comprises a horizontally-arranged base, a hand model is vertically fixed to the top of the base, the outer side wall of the hand model is wrapped with a tissue simulation layer, the outer side of the tissue simulation layer is wrapped with a skin simulation layer, and the movable end of the skin simulation layer is provided with an adjusting assembly used for adjusting the relaxation degree of the skin simulation layer. According to the acupuncture training device, under the action of the skin simulation layer and the tissue simulation layer, the skin and muscles of the human body are simulated, the accuracy of acupuncture needle feedback feeling is improved, under the action of the adjusting assembly, the relaxation degree of the skin simulation layer is adjusted, the simulation requirements of the skin of the human bodies of different ages are met, and the acupuncture training effect is improved.

The application discloses a kind of fine modeling methods for single-shaft gas turbine gas path system, including establishing single-shaft gas turbine gas path system's step-by-step compression compressor module, establishing single-shaft gas turbine gas path system's combustion chamber module, establishing single-shaft gas turbine gas path system's step-by-step expansion turbine module, based on the calculation method of compressor module outlet temperature, power consumption, the calculation method of each component mass, temperature of combustion chamber module outlet and the calculation method of turbine module outlet temperature, power, using Python simulation platform establishes single-shaft gas turbine gas path system model, obtains rated operating condition and actual operation data, the data of rated operating condition is input into the single-shaft gas turbine gas path system model built, and the dynamic characteristics of gas turbine are analyzed;It aims at solving the problem of insufficient accuracy caused by neglecting the change of specific heat capacity with temperature and the evolution of combustion product composition in the existing model.
