【摘要】:離心式冷壓機(jī)是大型低溫超流氦制冷系統(tǒng)的核心部件,其低溫、負(fù)壓環(huán)境以及高速條件使得軸承工作壽命受到挑戰(zhàn)。高溫超導(dǎo)磁懸浮軸承具有載重大、抗干擾性強(qiáng)、無需主動(dòng)控制等優(yōu)點(diǎn),因此應(yīng)用潛力巨大。針對(duì)磁懸浮力與轉(zhuǎn)子動(dòng)力學(xué)性能的綜合考慮,提出了一種優(yōu)化設(shè)計(jì)方法和懸浮載重比優(yōu)化指標(biāo),基于ANSYS磁場(chǎng)有限元軟件,設(shè)計(jì)并優(yōu)化完成一款小型高速超導(dǎo)磁懸浮軸承,懸浮剛度達(dá)到5.21×10~5N/m。相關(guān)結(jié)果表明,通過合理優(yōu)化,超導(dǎo)磁懸浮軸承具備足夠的懸浮剛度,可以滿足相關(guān)應(yīng)用需求。
[Abstract]:Centrifugal cold press is the core component of large-scale cryogenic superfluid helium refrigeration system. Its low temperature, negative pressure and high-speed conditions challenge the bearing's working life. High temperature superconducting magnetic levitation bearing has many advantages, such as heavy load, strong anti-interference and no need of active control, so it has great potential in application. In view of the comprehensive consideration of magnetic levitation force and rotor dynamic performance, an optimization design method and optimization index of suspended load ratio are presented. Based on the finite element software of ANSYS magnetic field, a small high speed superconducting magnetic bearing is designed and optimized. The suspension stiffness is 5.21 脳 10 脳 10 ~ 5 N 路m ~ (- 1). The results show that the superconducting maglev bearing has enough suspension stiffness and can meet the needs of relevant applications through reasonable optimization.
