Formation Technical Study Of Hemisphere Top Harmonic Oscillator

In the 1960s,The hemisphere resonance top is one kind of new tops which be appeared, It is composed of the hemispheroid harmonic oscillator, the static electricity drove cover , Reading out the based 3 parts. Becomed by the high quality factor(Q)fused silica glass materials precision sizing, And carries on metallized processing on the surface, The oscillator, the static electricity drove cover, the sensitive base precise erecting welded in together, and seals in a perfect vacuum vessel. Formed a complete and independent angle or the angular speed sensor .Compared with the traditional mechanical top and optics top, The hemisphere resonance top has the following superiority: In structure, Non-high speed rotor, Non-moves the part, Non-preheating, the short starting time, Signal band width, The low drifting noise, Withstand the big mobile overload, Anti-nuclear radiation, And undergo the influence which interrupted by the short time power source, The small volume, The light weight, The low power loss, The long life, Suitable spatial application, Therefore the research hemisphere top has the vital significance.In the consideration of quartz material nature and processes in the shape characteristic foundation, we design in the hemisphere resonance top the most important part--Harmonic oscillator formation craft. In the research, The simple point diamond turning technology processing mold, to ground the craft is used, The conformal grinding tool, The attrition remainder, The sputtering coating, The coating material, The laser cutting to conduct the research to realize the performance. This paper has builted the foundation to the future of our country's hemisphere top enterprise and the later deep researchs.
