| 摘 要： | 动弹模量是衡量混凝土质量是否合格的重要指标,设计出一种基于超声波的混凝土动弹模量检测设备。利用声波在不同密度的物质中传播速度不同的原理,穿过混凝土的超声波速度在一定的条件下能够反映出混凝土的弹性模量。综合利用微控制器技术、数据采集技术,对数据进行处理,快速测量出混凝土的动弹模量。该设备具有精度高、操作简便、易于携带等特点。

| Abstract: | The elastic modulus is an important index to measure the quality of concrete is qualified or not, this paper designed a kind of dynamic elastic modulus of concrete based on ultrasonic detection equip- ment. Using the acoustic velocity of different principle in different density of the material, the ultrasonic velocity through the concrete can reflect the elastic modulus of concrete under certain conditions. Comprehensive utilization of microcontroller technology, data acquisition technology, data processing, fast measure the loss modulus of concrete. The device has the advantages of high precision, simple operation, easy to carry features. |
