北京泡沫海绵落球回弹试验机  产品：HMLQ-500  

北京泡沫海绵落球回弹试验机  技术参数：
　1、钢球回落高度：        460mm（国标） 
                           500mm（美标）
　2、钢球直径：       ￠16mm
　3、落球回弹率精度： <1%
　4、被测试样尺寸：    长*宽*高=100 mm?100 mm?100（50）mm
  5、自动计算平均回弹高度
  6、自动计算平均回弹率
主要配置：
　 1、试验主机一台
   2、智能液晶控制操作系统一台
   3、钢球释放机构两套（手动释放机构1套、自动释放机构1套）
   4、钢球捕捉机构一套
   5、高度调节机构一组
   6、精密光电传感器一套
   7、钢球4个
   8、微型打印机一台
   9、水平校准机构一组

试验步骤：
将调节后的试样水平置于回弹仪的测试位置上，通过调节使钢球底部从固定位置到泡沫塑料表面的落下高度为460mm。在释放装置上固定钢球，然后使钢球自由落下。对每一个试样做三次回弹，取三次回弹中的最大值。每次回弹钢球应落在试样表面的同一位置上，并且两次回弹的时间间隔应控制在20s之内。如果钢球在回弹过程中碰到或弹出测量装置，所得数据无效，需重新补做。

Product: HMLQ-500

Technical parameters:

1. Steel ball drop height: 460mm (national standard)

500mm (American standard)

2. Steel ball diameter: ￠ 16mm

3. Precision of ball rebound rate:<1%

4. Tested sample size: length * width * height=100 mm ? 100 mm ? 100 (50) mm

5. Automatically calculate the average rebound height

6. Automatically calculate the average rebound rate

Main configuration:

1. One experimental host

2. One intelligent LCD control operating system

3. Two sets of steel ball release mechanisms (1 set of manual release mechanism and 1 set of automatic release mechanism)

4. A set of steel ball capture mechanism

5. One set of height adjustment mechanism

6. A set of precision photoelectric sensors

7. 4 steel balls

8. One micro printer

9. A group of horizontal calibration institutions

Experimental steps:

Place the adjusted sample horizontally on the test position of the rebound instrument, and make the drop height of the steel ball bottom from the fixed position to the foam plastic surface 460mm through adjustment. Fix the steel ball on the release device and allow it to fall freely. Perform three rebounds on each sample and take the maximum value from the three rebounds. Each rebound of the steel ball should fall onto the same position on the surface of the specimen, and the time interval between two rebounds should be controlled within 20 seconds. If the steel ball touches or pops out of the measuring device during the rebound process, the obtained data is invalid and needs to be re made.
