一、主要適用范圍及功能：

      海綿往復(fù)沖擊疲勞試驗機主要用于泡沫聚合材料的往復(fù)沖擊壓縮疲勞試驗，測定試樣的厚度減少值和硬度降低值（殘余變形率），并由此可以了解材料的動態(tài)疲勞特性。

本儀器控制系統(tǒng)采用德國西門子PLC，通過7寸彩色觸摸屏進行參數(shù)設(shè)置和操作，可以根據(jù)實驗需要設(shè)定沖擊負(fù)荷及實驗次數(shù)和沖擊厚度，本儀器的zui大特點是：試樣隨著沖擊時間和次數(shù)的增加，沖擊載荷小于設(shè)定沖擊負(fù)荷時能夠自動調(diào)節(jié)試樣托盤的高度，使沖擊負(fù)荷始終保持在設(shè)定的沖擊負(fù)荷范圍內(nèi)，當(dāng)試驗完成后，具有報警提示！

本儀器具有使用操作方便，性能可靠，測量精度高，是的海綿疲勞沖擊試驗機。

One, the main scope and function:

Sponge fixed load impact / reciprocating impact fatigue testing machine is mainly used for compression fatigue test reciprocating impact foam polymeric material, determination of the sample thickness reduction and the lower hardness values (residual deformation rate), and then we can know the dynamic fatigue properties of materials..

The instrument control system used in Germany Siemens PLC, parameter setting and operation by 7 inch color touch screen, can according to the number of impact load and test and impact thickness hypothesis test, the biggest feature of this instrument is: with the increasing impact time and the number of samples, which can automatically adjust the height of a specimen tray impact load is less than the set of impact load when the impact load, impact load is maintained in the set range, when the test is completed, with alarm!
