摘要
通过对钢琴音准稳定性的研究,探讨了木材钻孔直径对置入销钉的握着力的影响,确定了获取最大握着力的定性理论基础及试验方法,为众多类似问题的木结构设计提供了现实的设计方法:(1)选择弦轴板钻孔直径时,应每批进行实验;(2)模拟生产过程和正确选择实验条件非常重要;(3)强度校核时允许出现较小范围的危险区域(小于20°)。
Through the research for piano sound accurate stability discuss the timber diameter of drill hole for set up to enter dowel hold the influence that put forth effort. Determine to get biggest hold put forth effort determine the nature theoretical basic and test method, for the design of numerous similar problem that the design of timber structure offers reality method. First, when selecting the string axle board diameter of drill hole, it should be each batch of to test; Second, is simulated to produce course select experiment condition correctly very important; Third, strength allow to arise the dangerous area of less scope ( is smaller than 20°) when checking nucleus.
