The invention relates to a remote collaboration technology, in particular to a remote collaboration method of a product design model. By means of a virtual reality technology and a network communication technology, three-dimensional model operations are synchronized in different places through a message distribution mode. The method is characterized in that a remote communication calculating unitand a main communication calculating unit linked with each other by a public network are included, wherein remote product design models are collaborated by the public network. In the invention, a collaboration environment that can be mutually experienced by all participants is constructed by using integrated virtual reality simulation software, a three-dimensional CAD (Computer Aided Design) model is converted through a model conversion technology from a common format to a model format that can be supported by a system and message distribution is completed by a windows network communication, thus the remote collaboration method of the product design model of remote synchronization of the three-dimensional model operationsis realized.

The invention relates to a blade body sectional surface design method for a die forging blade. The blade body sectional surface design of the die forging blade is carried out according to the following requirements that: (1) firstly, a mathematical model of a blade body sectional surface line is built according to the coordinate values of the blade part blade body sectional surface points; (2) the inscribed circle of the air inlet and exhaust edges of the blade body is obtained according to the mathematical model; (3) the edge radius or the sectional line is optimized so that the sectional surface is precise and smooth; and (4) a blade forging element mathematical model is built on the basis, and in addition, the allowance increase is carried out. The method has the advantages that the design process is simple, the parametric design can be realized, the blade body sectional surface is smooth, the design model precision is high, and the like. The fast conversion and output process of the process files or parts, forging elements and the like can be realized, simultaneously, the resource sharing and the digital manufacture can be simultaneously realized, the design and manufacture period can be greatly shortened, the development process is accelerated, and the production efficiency is improved.

The invention discloses a function of enabling power temperature control by sending instructions from the ground, and the satellite independently performs periodic power temperature control management. The computer on the satellite first sets the power temperature control target value, and then counts all the active thermal control mechanisms included in the management objects. at t x The open or closed state at any time, and obtain the power of all thermal control mechanisms that are powered on, the upper and lower limits of the temperature control threshold and the temperature of the temperature control point, so that at t x The power of the thermal control mechanism that is turned on at the i-th road at any time is Q i , statistics at t x After the sum of the thermal control power of the m-channel thermal control mechanisms that are in the open state at all times, it will be compared with the power temperature control target value; according to the comparison result, the active thermal control mechanism is turned on or off, so that the total thermal control power and the power temperature control target value are as close as possible. may be equal; therefore, the present invention solves the problem of long-term and large-scale fluctuations in the total power of satellite thermal control, and can reduce the overall energy consumption of the satellite thermal control system to meet the development needs of low-energy thermal control technology.
