摘要
应用振动理论,对经过适张处理后的木工带锯条进行研究,确定张紧力与系统固有频率之间的关系,提出将带锯条的振动简化为弦的振动与受拉伸的梁振动。用电测法测应变换算张紧力,用频谱分析法测量系统的固有频率,理论解得到试验支持,同时计算张紧力和张紧应力。
The thesis studied the woodworking tension band saw blades by means of the vibration theories, made sure the relationship between tension force and inhesion frequency of its system. It brought forward that the vibration of the band saw blades may predigest to become the chordal vibration and the vibration of the drawn girders, measured its stress date to exchange its tension forces by means of electricity measure method, measured its inhesion frequencies of the system by means of frequency charts analysis method, and its theory results gained the experimental support, calculated its tension forces and tension stresses at the same time.
