Abstract

The longitudinal vibration model for wooden heterogeneous material was built in his paper , which was wood for analyzing the effects of free water gradient on longitudinal vibration frequency in its longitudinal direction . The results form experiments showed that this extents were ordered as fundamental , 2nd , and 3rd vibration modes . In addition , the measurement value of elasticity modulus after log storing 6 to 7 months was increased as 10 % as that of fresh log , which reason was from free water gradient .
- log,
- longitudinal vibration,
- resonant frequency,
- free water gradient,
- modulus of elasticity
