论钢琴弦轴的松紧

摘要

分析钢琴弦轴板的材料制作工艺，及其配件内部的力学原理。并通过对钢琴弦轴回转阻力矩测量得出的实验数据，证实调律造成弦轴松动的可能性极小，提出钢琴弦轴松紧适度的理论依据及其重要性。%The paper analyzed manufacture craft of piano pinblock, along with its mechanics principle of internal acces based on the experimental data of rotation on tuning pin of piano tuning pin, the author proved there is mathematical chance that the tuning pin will be adrift caused by tuning, and put forward the theoretical foundation and importance of moderate tightness.
