北京泡沫海綿落球回彈試驗機  產(chǎn)品：HMLQ-500  

北京泡沫海綿落球回彈試驗機  技術(shù)參數(shù)：
　1、鋼球回落高度：        460mm（國標） 
                           500mm（美標）
　2、鋼球直徑：       ￠16mm
　3、落球回彈率精度： <1%
　4、被測試樣尺寸：    長*寬*高=100 mm?100 mm?100（50）mm
  5、自動計算平均回彈高度
  6、自動計算平均回彈率
主要配置：
　 1、試驗主機一臺
   2、智能液晶控制操作系統(tǒng)一臺
   3、鋼球釋放機構(gòu)兩套（手動釋放機構(gòu)1套、自動釋放機構(gòu)1套）
   4、鋼球捕捉機構(gòu)一套
   5、高度調(diào)節(jié)機構(gòu)一組
   6、精密光電傳感器一套
   7、鋼球4個
   8、微型打印機一臺
   9、水平校準機構(gòu)一組

試驗步驟：
將調(diào)節(jié)后的試樣水平置于回彈儀的測試位置上，通過調(diào)節(jié)使鋼球底部從固定位置到泡沫塑料表面的落下高度為460mm。在釋放裝置上固定鋼球，然后使鋼球自由落下。對每一個試樣做三次回彈，取三次回彈中的最大值。每次回彈鋼球應落在試樣表面的同一位置上，并且兩次回彈的時間間隔應控制在20s之內(nèi)。如果鋼球在回彈過程中碰到或彈出測量裝置，所得數(shù)據(jù)無效，需重新補做。

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.
