Embodiment Construction

[0058] Below in conjunction with the accompanying drawings, the fine-tuning structure and method thereof for the quality characteristics of the aircraft wind tunnel model formed by light-curing molding of the present invention are described in detail:

[0059] see Figure 1 to Figure 5 As shown, a method for fine-tuning the quality characteristics of an aircraft wind tunnel model formed by light curing of the present invention comprises the following steps:

[0060] 1. Pre-design and process "quality characteristic fine-tuning structure"

[0061] Such as image 3 Shown is a schematic diagram of the structure of the projectile aircraft model. The origin of the coordinate system is at the vertex of the model, the x-axis is parallel to the axis of the projectile aircraft model and points to the rear, the y-axis is perpendicular to the longitudinal symmetry plane of the fuselage and points to the right, and the z-axis is in the longitudinal symmetry plane of the fuselage and poi...

Abstract

The invention provides a quality property micro-adjustment structure of an aircraft wind tunnel model quickly formed based on light curing and a method; the method comprises the steps that: 1. the aircraft wind tunnel model in the micro-adjustment structure is designed and processed in advance; 2. an optimal quality property micro-adjustment scheme is obtained through computer-assisted optimization: the quality property parameter of the aircraft wind tunnel model after being processed is measured and compared with a design value, and an error value is calculated as a target function; portfolios which are added or removed from the micro-adjustment structure serve as optimization variables; and an optimal quality property micro-adjustment scheme is obtained through computer-based automatic optimization. The invention provides the quick and automatic quality property micro-adjustment method which can provide the quality property simulation precision of the model.

Description

technical field [0001] The invention belongs to the fields of rapid prototyping technology and aircraft wind tunnel experimental model manufacturing, and relates to a method for fine-tuning the quality characteristics of a light-cured aircraft wind tunnel model. Background technique [0002] The aircraft wind tunnel model manufactured by light curing rapid prototyping technology can shorten the manufacturing cycle of the model and reduce the assembly process of the model, which is a new technology with application prospects. [0003] For special wind tunnel tests of aircraft (aircraft, projectiles, etc.), such as experiments such as free flight and spin, the quality characteristics of the model (including the weight, center of gravity and moment of inertia of the model) are strictly required. Due to the inevitable loss of precision in materials, manufacturing and assembly, there are certain errors in the quality characteristics of the completed model. When this error is gre...
