콘크리트 빔의 충격 성능

충격 3점 굽힘 설정을 한 콘크리트 빔에 대한 시험 수요가 높아지고 있습니다. 우리는 필요로 하는 최대 에너지에 따라 이 9450 과 9440을 시험에 추천합니다. 300mm 폭의 주문형 치구와 정밀 텁 인서트(tup insert)를 개발하였으며, DAS 와 Bluehill lMPACT 소프트웨어를 데이터 획득 용도로 사용하였습니다.

샘플은 400mm x 100mm x 100mm이며, 4.65m/s까지 시험됩니다. 속도는 필요로 한다면 더 높일 수 있습니다. 시험은 파괴 모드를 보여주며, 시험에서보다 훨씬 더 큰 에너지를 필요로 하는 더 큰 구조물을 시험하도록 설계되어 있습니다. 비교되는 결과의 종류는 흡수된 전체 에너지, 최대 하중, 파괴될 때까지의 에너지와 변형량입니다.

9300 시리즈는 고객이 그들의 재료가 충격을 받을 때 성능 특성을 알아내는데 도움을 주기에 적합합니다. 충격 시험을 통해 얻은 정보는 고객에게 데이터 기준치를 공급하여 그들이 실제 상황에서 그들의 혼합된 원재료가 어떻게 변하는지 알아내는데 쓰입니다. 다양한 온도에서의 충격 특성을 파악하기 위한 환경 챔버를 사용하거나 다른 종류의 시편 폭(span) 또는 다양한 충격 형태를 시뮬레이션 하기 위한 여러 치구들을 사용함으로써 더 폭넓은 시험을 할 수 있습니다.

复合装饰材料的冲击特性

后院搭建用建筑面板已日益增长为人们家庭生活尤其是对家居空间延伸、拓展不可缺少的重要角色。传统的建筑面板主要为压缩板，然而该材质由于造价、使用周期、外观、构建工期、维修和环境保护等原因正逐渐被新型木-塑材料所代替，即众所周知的复合装饰材料。

由多种木材和塑料的混合制造的复合装饰材料相对传统压缩板建材有着当然的优势：使用寿命长、色泽保持度好和少量的维修成本等。只有传统松木压缩板成本20~30%的复合装饰材料，两者的冲击性能相差无几。建筑面板遭受不同物件的冲击是家常便饭，如掉落的工具，院落物件，梯子或油漆罐等数不胜数，但各种各样不同种类的建筑面板的耐冲击性能是不同的。

对于复合装饰材料生产厂家的要求，我们的建议是采用英斯特朗 CEAST 9350 +高速系统冲击试验机，附件为：22.2KN示波冲击锤、1/2英寸半球冲头、1英寸球型冲头、DAS 8000数据采集系统和Visual-Impact软件包。该设备可装配不同类型的冲头和软件可设置不同的试验速度，建立起一系列的测试方案和不同能量等级的测试，使客户有可能对各种各样产品进行冲击性能的确定。

9350设备非常适合用以测试这类材料的冲击工作特性。有且只有示波冲击测试能提供生产商材料的基线数据，这可以帮助他们确定复合材料在生命周期内是如何变化的。该设备可适用的范围相当广，当然还可以包括环境箱，帮助解决样品在不同的温度条件下性能特性的确定，还可以使用不同的制具和冲击头模拟无支撑条件和其他冲击情况。

Drop Tower Impact Testing of Rocks and Stones

We have recently been in contact with a customer interested in a non-standard, but extremely interesting, way to perform impact tests. This company is specialized in the development of systems for selective fragmentation of various solids, especially in the mining and geosciences circuits. In these environments, improved methods for mineral comminution are continually being sought, pursuing the goal of achieving the required size reduction at a lower energy consumption level than conventional technology allows. Comminution is probably the largest energy consumer in most mine sites, with major implications for costs as well as environmental pollution. Applying different working conditions with their units they are able to pre-weak the rock or the stone to be comminuted. To understand how much their process is affecting the raw material, we suggest them a basic impact test by a means of a drop tower.

To help them to completely characterize the process, we have offer a 9450 drop tower equipped with a special support and a dedicated tup plus insert. The pre-weakened rock/stone will be placed for the test on the dedicated flat support. This support is connected to a reinforced adjustable height stand, which allows the proper positioning of the specimen for the impact. A dedicated tup, including a special reinforced flat insert, is used in combination with a reinforced tup-holder to impact the stone to be pulverized. Just selecting a specific mass and some basic test conditions (like the impact velocity or a drop height), it is possible to deliver on the specimen a well known amount of energy. The antirebound system is able to catch the tup preventing a second impact on the specimen. The weakened specimen will absorb a part of the impact energy fragmenting in many small pieces. The special box that is covering the impact area will allow to contain all pieces generated during the test, in order to perform further analysis and checks on the tested specimen.

To improve the understanding of the fragmenting process, is also possible to exchange the un-instrumented tup with a special one including a force sensor. The sensor, used in combination with a DAS and its related Bluehill software, will allow acquire the whole impact event and to perform more deeper analysis and studies.
