木排摩擦阻力的试验研究

AN EXPERIMENTAL STUDY ON THE FRICTION OF RAFTS

研究和设计运行水阻力较小的木排新排型,对发展我国木材水运事业,降低运输成本,提高经济效益都具有重要意义。对木排运行水阻力问题,国内外的某些学者也曾进行了一些研究工作。但由于受各种条件的限制,还有许多问题,尚未深入研究,例如木排摩擦阻力的换算问题。

This paper deals with the cause of the friction resistance of rafts and its affecting factors and advances the calculate method of the cofficient (Cf) of the friction resistance, which promoted the research on the problem of the runniny water resistance of rafts.
