Embodiment 1
[0052] In Embodiment 1, a 3D model of a certain type of unmanned aerial vehicle is selected as an example. This type of UAV is in a folded state before launch, such as image 3 shown. When launching, the booster (4) pushes the UAV out of the launch stand, and then the booster is separated from the body (1), and the 2 main wings (2, 6) and 2 tail wings (3, 5) of the UAV are deployed, The cruise engine (fixed on the body (1)) starts to work, and the UAV enters the cruise state, such as Figure 4 shown. The body (1) is the root component, and the booster (4), 2 main wings (2, 6) and 2 empennages (3, 5) are the second-level components connected to the body (1).

The invention provides a three-dimensional model equipment motion general control method. The method is characterized by including a computer, storing and operating management and control programs in the computer; equipping a three-dimensional model and establishing a tree-shape organization structure; establishing a coordinate system which includes a specific three-dimensional space coordinate system, an absolute coordinate system and a relative coordinate system, giving a calculation formula of a space conversion matrix M of the specific three-dimensional space coordinate system and a conversion method of converting from the relative coordinate system to the absolute coordinate system, and using the space conversion matrix M to realize motion control of a component in the absolute coordinate system; and giving motion control parameter configuration and a motion control process. In the invention, a condition that special software exploitation is performed aiming at specific model equipment is not needed; a software parameter is configured so that the motion control can be completed; the method possesses characteristics that a requirement to operation personnel is low, preparation time is short and there are many suitable models; and versatility is good and a practical value is high.
Description
technical field [0001] The invention belongs to the field of equipment testing, and relates to a computer simulation technology for equipment three-dimensional model motion simulation, in particular to a general control method for equipment three-dimensional model mechanism motion. Background technique [0002] The motion simulation of the equipment 3D model mechanism drives the 3D model motion mechanism to perform spatial motion through external data, which is used to truly simulate the motion state of the equipment in the equipment test and build the 3D test situation. [0003] Mechanism movement during equipment test includes component rotation, translation, separation, throwing action or a combination of the above actions. The working principle, internal structure and mechanism movement mode of each type of equipment are different. When performing motion control of the 3D model of equipment, it is necessary to configure the drive data, control instructions, and component...
