1手提电刨噪声源于提电刨刨木板时,噪声级达到l(:X:kll一12ffe。对环境构成噪声污染。该噪声发生机理是:刀片所在的轴高速旋转时,两把刀以固定频率冲击木板。在激振力及其反力作用下,木板和电刨同时发声。在木板较薄时其固有频率等于或接近作用力频率,木板引起共振,此
A portable planer noise from planing planing wood board, the noise level reached l (: X: kll a 12ffe. The noise pollution on the environment. The mechanism of noise occurs: the blade where the shaft rotates at high speed, the two knives to Fixed frequency impact wood.In the exciting force and its reactionary force, wood and planer sound simultaneously.When the wood is thin, its natural frequency is equal to or close to the force frequency, wood caused resonance, this
