中文拼音 [jiǎnzhèncítiě]
減振磁鐵
英文
damping magnet-
Ndfeb magnet is mainly made of neodymium iron and boron, with excellent magnetic property abundant raw material and reasonable prices, ndfeb magnet can be used as an ideal magnet in mini - motor permanent magnetic resonance sound device magnetic suspension system, magnetic transmission machine and iatrical apparatus and etc. for ndfeb, its surface is usually treatd with some special methods. the surface treatment method include zine nickel tin silver gold plating phosphor and spray epoxy resin etc
其主要應用在微特電機、永磁儀表、電子工業、汽車工業、石油化工、核磁共振裝置、音響器材、磁懸浮系統、磁性傳動機構和磁療設備等方面。釹鐵硼磁鐵容易生銹、氧化，所以對釹鐵硼磁鐵，其表面通常需作電鍍處理，如鍍鋅、鎳、銀、金等，也可以做磷化處理或噴環氧樹脂來減慢其氧化速度。The dissipative attenuation mechanism of the mn - zn ferrite that involved the natural resonance, the piezoelectric resonance and the magnetic hysteresis loss are also studied
本文還分析了錳鋅鐵氧體自然共振、磁滯損耗和疇壁共振等磁極化機制衰減吸收電磁波的各種機理。Based on the special property of magnetic fluid ( mf ), we fill the magnetic fluid into the working clearances of the servo valve torque motor. one side, the magnetized magnetic fluid can exert a damping torque on the torque motor armature and reduce vibration of the armature ; on the other side, it can improve the magnetic circuit efficiency of the torque motor because of the magnetic fluid ’ s larger magnetic permeability
基於磁流體所具有的特殊性質，將磁流體添加到伺服閥力矩馬達的工作間隙中，一方面磁流體被磁化后可增大銜鐵的阻尼力，減少振動;另一方面由於力矩馬達氣隙中磁導率的提高，使氣隙中的磁通量增大，力矩馬達的磁路效率和輸出扭矩將增大，因此可以提高力矩馬達的固有頻率和伺服閥的響應速度。With heat treatment temperature increasing, the complex permittivity of w - type ferrite hollow microspheres decreased ; " firstly increased and then decreased, increased and there was an obvious resonance peak ; the complex permittivity ? of m - type ferrite hollow microspheres increased ; " increased, " was basically unchangeable
隨熱處理溫度的升高， w型鐵氧體空心微球的介電常數降低；磁導率實部先增加后減少，虛部增加並出現明顯的共振峰； m型鐵氧體空心微球的介電常數增加，磁導率實部增加，虛部變化不明顯。分享友人
