木质材料力学性能无损检测方法的研究现状与趋势

木质材料用途广泛，在建筑、家具和包装等领域发挥着重要作用。目前，木材无损检测技术发展很快，应用到木材性质检测的无损检测方法已达几十种，然而对木质材料力学性能的检测还处于相对初级阶段，具有较大的挑战性。本文对木质材料力学性能的无损检测方法和原理进行归纳与总结，阐述几种主要检测技术（如应力渡检测、超声渡检测、振动法检测）的国内外研究现状、检测特点及存在问题。在此基础上，提出木质材料力学性能无损检测技术的发展趋势。

Research Situation and Trend on Non Destructive Testing Method of Wood Material Mechanical Properties

Wood materials are widely used and play an important role in the fields of construction, furniture and packaging, etc. Currently, wood non-destructive testing technology develops rapidly and application of non -destructive testing method in the detection of wood properties has reached dozens. However, detection on wood material mechanical properties is still at a primary stage and it would face many challenges. This paper summarized the basic methods and principles of non-destructive testing method of wood material mechanical properties, presented the research status at home and abroad, testing characteristics and existing problems of several main testing technologies （ such as stress wave testing, ultrasonic wave testing, vibration testing）. On the basis of that, the authors proposed the developing trend on non-destrnctive testing technology of wood material mechanical properties.
