In this paper, an Automatic Test System runtime platform based on the ATML standard is designed and implemented. Firstly, the paper analyzes functions and internal relationship of the basic components of TPS based on ATML, and gives the parse method of TPS. Afterwards, the overall architecture design and functional division of the runtime platform were carried out. Realize the execution logic of the runtime platform by generating the Test Operation Tree and analyzing the test purpose of different Operation Type. Then, the software execution process during debugging control and simulation test is given, and finally the method of debugging information monitoring and persistence is explained. In addition, this paper introduces the resource allocation methods when calling the underlying test resources. By using the architecture described in this paper, the interchangeability and test efficiency of test programs can be improved.
A parameterized modeling and spatial layout method for marine parallel shaft gear transmission system is proposed using the idea of parameterized modeling and the characteristics of Open CASCADE technology, combined with the structural parameters of transmission system feature units and the logical relationship of transmission system. Based on the basic structural parameters and topological principles, parameterized models of gears, bearings, couplings, shafts, etc. were designed for typical units of the transmission system. The initial model generation of the transmission system shaft system was achieved. In response to the complexity and diversity of the spatial layout of the transmission system, a set of shaft system spatial layout schemes was summarized to improve the configuration efficiency of the marine transmission system, it has reference significance for the configuration design stage of the transmission system.
The paper takes marine transmission as the research object, generates the schemes of transmission automatically based on graph theory and maps the selected transmission graph theory model scheme into a more intuitive transmission configuration for subsequent design. The main contents of this article are as follows: Extracting the knowledge from existing Marine transmission data; generating the graph theory models and numbering the vertexes and edges of each model; converting graph-theoretic models into mathematical language for processing by computers; formulating screening rules for graph model schemes; listing the screened graph model solutions and mapping the selected transmission graph theory model scheme into transmission configuration. By using the methods described in this paper, designers can achieve a shortened design cycle for marine transmissions and improve design efficiency.
