The current study is to investigate the relationship between the sound radiation and enclosure vibration by using a laser vibrometer. 利用激光測振儀，測試了箱體振動(dòng)速度隨頻率的變化，分析了前幾個(gè)振動(dòng)模態(tài)的聲輻射能力。
Based on the operation of a slab caster which is equipped with hydraulic oscillators, the mould friction and oscillation velocity were measccred. 基于液壓振動(dòng)裝置的板坯連鑄試驗平臺，對結晶器摩擦力和振動(dòng)速度進(jìn)行了檢測實(shí)驗研究。
