Embodiment 1
[0051] The first embodiment of the present invention provides a method for moving the position of a vehicle beam, including:
[0052] 101: Modularization is performed before the amount of movement, including:
[0053] Establish set A: The set A contains target beams in the same direction;
[0054] Establish set B: The set B contains overlapping parts connected to the target beam in set A;
[0055] Establish set C: The set C contains the connection relationship information between the target beam in the set A and the overlapping parts in the set B.
[0056] The system automatically classifies the car beams according to the position and direction of each car beam. For example, horizontal beams are class I beams, longitudinal beams are class II beams, and diagonal beams are class III beams. They have common orientation characteristics. Class beams form set A, for example: set up a set A of transverse beams (A1, A2, A3).
[0057] At the same time, in order to ensure that the connection rela...
Embodiment 2
[0069] The second embodiment of the present invention proposes another method for moving the position of a vehicle beam, which specifically includes:
[0070] 201: Modularization is performed before moving the beam, including:
[0071] Establish set A: The set A contains target beams in the same direction;
[0072] Establish set B: The set B contains overlapping parts connected to the target beam in set A;
[0073] Establish set C: The set C contains the connection relationship information between the target beam in the set A and the overlapping parts in the set B.
[0074] The operation method of this step is the same as 101. Set up set A (A1, A2, A3), set B ((A1, D1), (A2, E1)), set C ((A1, D1, weld, 2 layers , 5mm), (A2, E1, bolted, 2 layers, 4mm)), the details are not repeated here.
[0075] 202: Select the target beam A1 to be moved from the set A;
[0076] The designer can select the target beam to be moved from the set A (A1, A2, A3), for example, select the A1 beam to move. Of c...
Embodiment 3
[0092] The third embodiment is combined with the actual vehicle beam design process, and the technical idea of realizing the reasonable arrangement of the beam position in the vehicle design includes three parts. First, it is programmed to automatically move the beam position and parameterize the beam moving distance L; second, the beam is moved to a new position and submitted for calculation automatically; third, the calculation result is automatically extracted.
[0093] Such as Figure 4 , Figure 5 Shown.
[0094] 401-403, perform model processing, establish set A, set B, and set C;
[0095] Including the connection point processing in advance, so that the connection point connected to each beam is a two-layer connection point connection form. For non-two-layer welding (for example, three-layer welding), treat it as a two-layer connection point connection.
[0096] Create set A, such as Figure 4 with Figure 5 As shown, Figure 4 Is the bottom of the car, Figure 5 Roof struct...
