General spacecraft digital model design method and device for comprehensive test

The invention discloses a general spacecraft digital model design method and device for comprehensive testing. The method comprises the following steps: constructing a spacecraft digital model; constructing a spacecraft space environment digital model and associating the spacecraft space environment digital model with the spacecraft digital model; constructing a spacecraft ground test equipment digital model, and performing association to obtain a second association model; setting an association test mode for the second association model to obtain a first optimization model; configuring a control interface of the first optimization model to obtain a second optimization model; optimizing the state attribute of the second optimization model; and performing a comprehensive test based on the optimized second optimization model. According to the method, spacecraft test design work is applied in advance in a simulation verification stage, a test method tool set can be directly inherited and used in a spacecraft com
