Silencing sheet mounting method

Abstract

The invention relates to the technical field of silencing equipment, and provides a silencing sheet mounting method which comprises the following steps: establishing a barrel actual model and a three-dimensional theoretical model comprising a barrel and a mounting seat in three-dimensional software; coupling the actual cylinder model with the three-dimensional theoretical model to obtain the position of the mounting seat in the actual cylinder model; the position of the mounting base is positioned on the barrel, and the mounting base is fixed to the corresponding position in the barrel; and the silencing sheets are conveyed into the cylinder body and are mounted on the corresponding mounting seats. According to the method, the actual cylinder model and the three-dimensional theoretical model are established in the three-dimensional software, and the two models are coupled to obtain the position of the mounting seat in the actual cylinder model, so that the position of the mounting seat on the cylinder can be accurately positioned; the problem that in the prior art, due to the fact that the measurement precision control difficulty is large, the positioning precision of the installation base is low is solved, the positioning precision of the installation base is guaranteed, and the follow-up installation precision of the silencing sheet is improved.

Description

technical field [0001] The invention relates to the technical field of muffler equipment, in particular to a method for installing a muffler sheet. Background technique [0002] In the aerospace field, many flight data need to be obtained through simulation tests. However, during the simulation test, the airflow speed of the exhaust device is large, which will generate large noise and cause noise pollution to the surrounding environment. Install noise reduction equipment on the gas device to reduce noise. [0003] There is a muffler device, such as figure 1 As shown, the cylindrical body 10 includes a horizontally arranged circular cylinder 10 , and at least two groups of mufflers 30 are arranged in the cylinder 10 along the longitudinal intervals of the cylinder 10 , and each group of mufflers 30 includes a transverse interval along the cylinder 10 . 5-8 muffler sheets 30 are provided; two mounting seats 20 are arranged above and below each muffler sheet 30, and the mount...

Problems solved by technology

[0005] Since the inner surface of the cylinder is curved, traditionally theodolite, steel tape and wire pendant are used to locate the position of the mounting seat in the cylinder. However, this positioning method is inconvenient to operate and difficult to control the measurement accuracy, which leads to The positioning accuracy of the seat is low, which seriously restricts the installation accuracy of the muffler
