簡支梁沖擊試驗機
概述：
本試驗機主要用于硬質塑料（包括板材、管材、塑料異型材）、增強尼龍、玻璃鋼、陶瓷、鑄石、電絕緣材料等非金屬材料沖擊韌性的測定。廣泛應用于化工行業、科研單位、大專院校質量檢測等部門。
本儀器滿足主要技術參數完全符合ISO179、GB/T1043、GB/T18743、GB/T2611、JB/T8762、DIN8078、和Q/QJAR521標準的要求。是一種結構簡單、操作方便、數據準確可靠的沖擊試驗機。
工作原理：
用已知能量的擺錘打擊支承成水平梁的試樣，由擺錘一次沖擊使試樣破壞，沖擊線位于兩支座正中，以沖擊前、后擺錘的能量差，確定試樣在破壞時所吸收的能量，然后按試樣原始橫截面積計算其沖擊強度。

Charpy Impact Testing Machine
Overview
This testing machine is primarily used for determining the impact toughness of non-bllic materials, including rigid plastics (plates, pipes, plastic profiles), reinforced nylon, fiberglass reinforced plastic (FRP), ceramics, cast stone, and electrical insulating materials. It is widely used in chemical industries, research institutions, universities, and quality inspection departments.
This instrument fully complies with the requirements of standards such as ISO 179, GB/T 1043, GB/T 18743, GB/T 2611, JB/T 8762, DIN 8078, and Q/QJAR 521. It is a simple-structured, easy-to-operate, and reliable impact testing machine with accurate data.
Working Principle
A pendulum hammer with known energy strikes a specimen supported as a horizontal beam. The specimen is broken by a single impact, with the impact line located at the midpoint between the two supports. The energy absorbed by the specimen during failure is determined by the energy difference before and after the impact. The impact strength is then calculated based on the original cross-sectional area of the specimen.
