ActiveCN102750739AEnables direct 3D interpretation analysisQuick response3D modellingSurface fittingWorkload
The invention relates to a three-dimensional modeling technology and discloses a construction method of a three-dimensional geologic model. The construction method solves the problem that massive auxiliary two-dimensional analysis must be carried out when the three-dimensional geologic model is built traditionally, so that during the modeling process, the workload is large, a modeling process is complex and the model cannot be automatically updated. According to the construction method, direct three-dimensional interpretation analysis of geological information is achieved in a dynamically and controllably adjusted surface fitting (interpolation) mode, and two-dimensional analysis results are no longer essential bases; an engineering geological base information database closely combined with production practice is established, and collecting work of geological base information and information storage management are carried out on the basis of three-dimensional analysis interpretation; the base information is continuously enriched and perfected along with a production schedule and can be rapidly reflected to the analysis and adjusting process of the three-dimensional geologic model; and three-dimensional direct output or two-dimensional sectioning output of geologic results is correlated with the engineering geological database, and normalized automatic output is formed. The construction method is suitable for three-dimensional modeling for geology.

Oil charging accurate control method for wet clutch

ActiveCN105805186AQuick responseShorten filling timeClutchesGearing controlSystem pressureOil temperature
The invention relates to an oil charging accurate control method for a clutch in the gear shifting process of a wet double-clutch automatic transmission. The oil charging process of the clutch is divided into four stages. In the first stage, oil is rapidly charged into the clutch, the oil charging pressure satisfies the equation that P1=P0+delta P1, P0 is the target pressure, and the most appropriate delta P1 value under each oil temperature and gear shifting type is found out through an experiment mode by considering the influences of the oil temperature of a gear box and the gear shifting type. In the second stage, oil charging compensation is carried out on the clutch subjected to rapid oil charging, the oil charging pressure satisfies the equation that P2=P0+delta P2, and the most appropriate delta P2 value under each gear shifting type and system pressure is found out through an experiment mode by considering the influences of the gear shifting type and system pressure. In the third stage, oil charging waiting is carried out on the clutch, the oil charging pressure satisfies the equation that P3=P0, and the third stage is ended when the pressure of the clutch reaches 95% of the target pressure. In the fourth stage, oil charging is finished. By controlling the pressure of each stage, rapid and accurate response of the pressure of the oil charging process of the clutch can be realized, and impact caused by pressure overshoot of the clutch is avoided.
