One, effectiveness for a given period of time of vibration of Beijing satellite manufactory applies workpiece   1, aluminium alloy beam: Length 2 meters, before   of 140mm of × of 120mm of = of width × ply two end become warped after finish machining, error 8mm or so, craft requirement 1mm, after using oscillatory effectiveness for a given period of time, solve completely. 2, alloy housing washer (circle) diameter of     1) 2.

8 meters, use hot effectiveness for a given period of time before, use oscillatory effectiveness for a given period of time at present. 2) is direct 3.

3 meters, use hot effectiveness for a given period of time before, use oscillatory effectiveness for a given period of time at present. 3, aluminium board: Long × wide × is tall:   of 8mm of × of 300mm × 150mm is hot before flatness is out of shape after finish machining of effectiveness for a given period of time 1.

5mm, craft requirement 1mm, after using oscillatory effectiveness for a given period of time: 0.

7mm. 2, one aircraft group of Inner Mongolia some product over all dimension is big, and some spare partses already arrived final position, cannot undertake heating up effectiveness for a given period of time; Its component is in treatment process, as a result of stress release, generation is larger be out of shape, the influence machines precision. Natural effectiveness for a given period of time is taken between working procedure, effect difference, cycle is long. After installing solder to the component in the light of afore-mentioned problems (before finish machining) increase working procedure of oscillatory effectiveness for a given period of time, the deflection after Kong Jingjia of rear Φ 593H7 is versed in decreases 60% , of the bridge opening after decreasing long grind a quantity, reach design target. Have oscillatory effectiveness for a given period of time to 18 workpiece again, workpiece rear aperture is left, right in all 36, out of tolerance of the 1 aperture after its detect, percent of pass 94.

4% . The circularity percent of pass of product housing washer 100% , eliminated stress technology to replace original temper working procedure with vibration. 3, circularity of assembly of 1884H11 of Φ of the housing washer on company of group of northward heavy industry detects record (aluminium alloy) result of actual measurement of requirement of craft of number of result of actual measurement of number craft requirement 0010.

3   4, plant of machine of spaceflight state-operated elegance and talent solved nearly 10 years to tackle key problem not the technical difficult problem of fruit: The dimension precision of cast of body of magnesium alloy cabin reachs stability. Be out of shape after finish machining of former hot effectiveness for a given period of time for 3mm, through " navigate person " after handling precision work, be out of shape for 0.

23mm   5, the circularity percent of pass of housing washer of aluminium alloy of Chang'an automobile group 100%   6, the Chinese People's Liberation Army 7410 factories solder the dimension precision of gear-box body achieves a design to ask entirely 7, workpiece of aluminium alloy of high strenth of academy of craft of Beijing aviation material, the 40-50% of percent of pass after machine of the original effectiveness for a given period of time that use heat is machined, should use my firm " navigate person vibration eliminates II of stress expert system " hind, batch handles more than 50 thousand, the percent of pass after its machine is machined is in 95% above.
