Description
技术领域technical field
本发明涉及一种测试设备，尤其是一种载荷试验机。The invention relates to a testing device, especially a load testing machine.
背景技术Background technique
玻璃钢格栅又名玻璃钢格板，是一种用玻璃纤维作增强材料，不饱和聚酯树脂为基体，经过特殊的加工复合而成的一种带有许多空格的板状材料，玻璃钢格栅可以作为结构材料，用作有腐蚀环境的地板、地沟盖板、平台、舰艇甲板、楼梯、栈道等。具有耐腐阻燃、无磁绝缘、颜色鲜艳样、有多种样式形式备选等特点。FRP grating, also known as FRP grating, is a plate-like material with many spaces that uses glass fiber as a reinforcing material and unsaturated polyester resin as a matrix. As a structural material, it is used as a floor, trench cover, platform, ship deck, stairs, plank road, etc. in a corrosive environment. It has the characteristics of corrosion resistance and flame retardant, non-magnetic insulation, bright colors, and various styles and forms for selection.
玻璃钢格栅在其使用过程中，往往会承受一定载荷的冲击作用，时间长了，玻璃钢格栅就会产生疲劳损伤，从而导致失效不能使用。所以在玻璃钢格栅出厂前，利用试验手段快速而有效地检测出冲击对玻璃钢格栅的影响，从而判断其寿命是否满足设计需要。During its use, the FRP grating is often subjected to the impact of a certain load. After a long time, the FRP grating will suffer from fatigue damage, which will cause it to fail and cannot be used. Therefore, before the FRP grating leaves the factory, test methods are used to quickly and effectively detect the impact of the impact on the FRP grating, so as to judge whether its life meets the design requirements.
目前，对玻璃钢格栅的试验还没有相关的测试装置，从而无法对玻璃钢格栅进行检测是否符合均匀载荷的标准。At present, there is no relevant test device for the test of FRP grating, so it is impossible to test whether the FRP grating meets the standard of uniform load.
