[0004] Traditional human-computer interactive painting Figure 1 It is generally necessary to define geometric elements with precise dimension values, and each input line must have a definite position. Once the graphics are established, even if the structure is similar, if you want to change the size of the graphics, you can only edit the graphics. In engineering design, New product design inevitably requires repeated revisions and optimizations; on the other hand, parts of the same basic structural form have a certain similarity in their graphic structures, often only in different sizes, and their graphics vary with the size parameters. change with change

Embodiment

[0049] Aiming at the needs of carrying out heat intensity tests for metal heat protection systems of various sizes, a flat-plate quartz lamp heater is designed, and a flat-plate quartz lamp heater for this test is designed by using the present invention. The specific steps are:

[0050] Step 1: Determine the design parameters of the flat-plate quartz lamp heater. The parameters include the distance H between the reflector and the flat plate, the length of the lamp tube Llight, and the number of lamp tubes LightNum.

[0051] Step 2: Customize the interface based on the design parameters determined in Step 1.

[0052] Step 3: Use VisualBasic language to write programs based on CATIAAutomation. In the main program, define the distance H between the reflector and the platform, the length of the lamp tube Llight, and the number of lamp tubes LightNum. The three-dimensional drawing of the bracket was directly drawn by CATIA software. Create the part document of the guide strip, es...

Abstract

The invention discloses a parametric design method for a quartz lamp heater, which belongs to the technical field of aerospace vehicle environment simulation. The invention uses constraints to express the shape characteristics of the quartz lamp heater, defines a set of parameters to control the design results, modifies the design model of the quartz lamp heater by changing the parameters, and creates design schemes of the quartz lamp heater for different test objects and test conditions . This method provides a fast and practical design method for quartz lamps for test designers specialized in structural thermal strength, and realizes the rapid design of ground thermal tests, thereby achieving the purpose of reducing test costs and improving test quality and level.

Description

technical field [0001] The invention relates to a parametric design method for a quartz lamp heater, which belongs to the technical field of aerospace vehicle environment simulation. Background technique [0002] Quartz lamp radiant heater belongs to high heating rate radiant heating equipment, which evaluates the heat-resistant ability of the heat-resistant structure by heating the surface of the test object. The thermal inertia of the quartz lamp is small, it is convenient for electric control, and it is very suitable for the transient characteristics of pneumatic heating. At the same time, it is small in size and high in power, and can be assembled into heaters of different sizes and shapes, and can obtain 1200kW / m on a large area 2 ~1300kW / m 2 It is suitable for both large-scale full-scale structural thermal tests and small-scale thermal tests. It has good adaptability to test pieces with complex shapes and structures, and can meet the requirements of most structural t...
