Using an extensible object-oriented query language in multibody system analysis
Since modern software tools produce large amounts of engineering data, the demand for efficient data management may be met by integrating database technology with engineering applications. This approach is taken in MECHAMOS, which is a previously reported system for symbolic and numeric multibody system (MBS) analysis. This work focuses on the high level analysis performed with the available query language in MECHAMOS. The data management is considerably improved in this system compared to a traditional MBS analysis tool. For instance, MECHAMOS can easily combine and compare MBS data not only within the same MBS model but also over several MBS models, each governing different equations of motion. To avoid redundant computations in such analyses a simplified materialisation mechanism is implemented. Examples are given of combining and comparing both symbolic and numeric MBS data
