Problems solved by technology

The adjustment frame involved in this paper is a traditional beam frame, which has the following disadvantages: 1. The number of lateral position points is limited, and it is impossible to realize the investigation of the resistance performance under various side body spacings; 2. The adjustment of lateral position and draft is inconvenient and requires Disassembly and assembly of the side body reduces the efficiency of the experiment; 3. The accuracy of lateral position and draft adjustment is not high

Embodiment Construction

[0022] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings and examples:

[0023] Adjusting frame for trimaran model test ( figure 1 ) is connected by the main body to the adjustment part ( figure 2 ), the side body connection adjustment part ( image 3 ) and the transverse slide part ( Figure 4 )composition. Such as figure 1 and figure 2 As shown, the main body adjustment part includes a base plate 1 , a base 12 , a slider 2 , a top screw 9 , a connection hole 3 and a connection screw 13 . The base 12 is located below the base plate 1 and is fixedly connected with the base plate 1. The base 12 and the base plate 1 are provided with through connecting holes 3 for connecting the connecting screws 13 to the main deck of the ship model. Both ends of the base plate 1 are connected with slides. The block 2, the slide block 2 and the base plate 1 are provided with threaded through screw holes, which are fixed in the c...

Abstract

The invention provides a trimaran model test alignment jig comprising a main body connection adjusting part, a lateral body connection adjusting part and a transverse slipway part, wherein the main body connection adjusting part comprises two substrates, two ends of each substrate are provided with a slide block A and a top thread A, and each substrate is connected with two bases; the lateral body connection adjusting part comprises two clevises, two ends of each clevis are provided with a slide block B and a top thread B, the clevis is provided with a connection adjusting hole, and a connection adjusting bolt is arranged in the connection adjusting hole and is provided with a fastening nut; the transverse slipway part comprises two chutes; and the slide blocks A on two ends of the substrates and the slide blocks B on two ends of the clevises are arranged in the chutes. The invention can adjust the lateral body space and the lateral body draught of the trimaran and is suitable for various widths of main bodies and lateral bodies. The alignment jig has simple structure and convenient use and can improve the precision and the efficiency of the trimaran resistance prediction and lateral body layout optimization model tests.

Description

technical field [0001] The invention relates to an experimental device, in particular to a trimaran model test adjusting frame. Background technique [0002] The trimaran is a new high-performance ship developed to meet the needs of anti-submarine warfare in the 21st century. Compared with conventional single-displacement ships, it has good stealth performance, low navigation resistance, wide upper deck, and strong survivability. Good stability and seakeeping. [0003] The trimaran mainly reduces the navigation resistance from the beneficial wave-making interference between the hulls, and the layout of the side hulls at a certain speed has a great influence on the resistance of the trimaran. So far, the theoretical prediction effect of trimaran resistance is not satisfactory, and the theoretical optimization of side body layout is not reliable. Experiments are still the main method for trimaran resistance prediction and side body layout optimization. In the trimaran resist...
