Embodiment Construction
[0032] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0033] Such as Figure 1-9 As shown, a method for deploying a channel transition plate provided by the present invention includes the following steps:
[0034] S1. Establish a three-dimensional model when the flow channel transition plate 2 is smoothly connected with the hull plate 3, and draw a plurality of longitudinal section lines parallel to each other on the established three-dimensional model to form a longitudinal section line type 8;
[0035] Such as Figure 1-2 Shown is a schematic diagram of the linear relationship between the flow channel and the hull, which includes a flow channel 1 , a hull outer plate 3 and a flow channel transition plate 2 connecting the ...

The invention relates to a method for deploying a flow channel transition plate, which is based on the only line shape of the flow channel transition plate, a plurality of equal divisions of the top view projection lines of the outer contour of the flow channel transition plate, and connecting corresponding equal division points to form etc. Divide the line, and then back-project the equal line to the 3D model, connect it to form a new flow channel transition plate line type, connect the equal line projections along the diagonal to form a diagonal line, and then back-project the diagonal line to the 3D model, And connect to form a diagonal line, measure the actual size of each bisection line and diagonal line, and draw the length of each line from the middle to both sides in order, so as to realize the expansion of the flow channel transition plate. In addition, the present invention can also establish the model of the sample box according to the three-dimensional model and the new line shape of the flow channel transition plate, thereby solving the technical problem in the prior art that a suitable and accurate processing sample box cannot be cut.
Description
technical field [0001] The invention relates to the field of ship hull construction, in particular to a method for deploying a channel transition plate. Background technique [0002] The runner is an important structure of the waterjet propulsion ship, and it is generally connected smoothly with the outer plate of the hull through the runner transition plate, as a part of the hull of the ship. The line shape of the channel transition plate is relatively complex, the precision is high, and the shape is irregular. Its accurate deployment and processing are the most difficult points in the construction of water jet propulsion ships. The only hull line type is not enough to develop the flow channel transition plate parts, nor can it provide suitable sample box processing. The runner transition plate can only be roughly unfolded, and a certain margin is added, which reduces the blanking accuracy of the plate. [0003] Secondly, it is impossible to cut a suitable and accurate pr...
