The invention discloses a quartz lamp and laser combined type complex curved surface heating device and method. Through the heating mode, the complex thermal field loading task of micro curved surfaces such as aero-engine blades can be achieved, and the specific effect includes that the temperature difference of 300 DEG C or above and the overall temperature of the whole blades being 1000 DEG C orabove are achieved within the small distance of 10 mm on the heating surface. The main implementation method of the heating mode provided by the invention comprises the steps of carrying out thermalloading on a heated workpiece through quartz lamps, and forming a basic temperature thermal field by adjusting the power of the quartz lamps at different positions; and for an area with the high localtemperature gradient, irradiating and heating the local part through a laser to achieve the high-temperature heating task of high-temperature stationary points on the surface. According to the quartzlamp and laser combined type complex curved surface heating device and method, high-temperature complex temperature field establishment of small high-temperature large-temperature-gradient test pieces such as aero-engine high-pressure turbine blades can be completed, and the establishment task of the local extremely-high accurate temperature gradient can be completed.
Description
technical field [0001] The invention belongs to the technical field of quartz lamp heating, and in particular relates to a quartz lamp and laser compound complex curved surface heating device and method. Background technique [0002] Blades are the most critical link in the development of advanced gas turbines and aero-engines. The test of gas turbine blades and aeroengine blades is of great significance to the design, analysis and inspection of blades. The service temperature of blades of advanced gas turbines and aeroengines has the characteristics of small heating area, high limit temperature, and complex thermal field distribution. So how to achieve a thermal field temperature exceeding 100°C in a small area of 10mm. [0003] The blades usually use resistive heating and quartz lamp radiant heating for thermal assessment tasks. The way of irradiation heating of quartz lamp is to radiate infrared radiation to the test piece through the heating tungsten wire inside the...
