Embodiment 1
[0047] Below, the present embodiment further describes the present invention in conjunction with the accompanying drawings and specific implementation methods:
[0048] refer to figure 1 As shown, the present embodiment provides a multidisciplinary joint simulation system based on virtual time, including:
[0049] The FMU model loading module 1 is used to output the input tool requirements as FMU functional sub-models, and the functional sub-models are used as the input of the static architecture building blocks;
[0050] The integrated development environment 2 is used to assemble the input functional sub-models, describe the parameterized structure of each functional sub-model, obtain multiple single-disciplinary models, and combine the input single-disciplinary models with time-based construction The time series model of the system architecture is connected to obtain the redundancy mixed model;
[0051] The timing scheduler 3 is used to schedule the single-subject model c...
Embodiment 2
[0077] refer to figure 2 As shown, the embodiment of the present invention provides a multidisciplinary joint simulation method based on virtual time, including the following steps:
[0078] S1. Obtain the FMU function sub-model;
[0079] S2. Assemble the input functional sub-models, describe the parametric structure of each functional sub-model, and obtain multiple single-subject models;
[0080] S3. Connect the input single-disciplinary model with the time-series model of the system architecture based on the time dimension to obtain a redundant mixed model, and each single-disciplinary model is bound to a scheduling task;
[0081] S4. According to the virtual time corresponding to the single-subject model in the redundancy parallel task, the timing scheduler schedules the single-subject model corresponding to the minimum scheduling granularity in the current execution sequence;
[0082] S5. Use the timing modeling simulation scheduling engine to independently model the va...
