Understanding the accuracy of the impact test machine

Impact testing machineComplete sets of equipment, impact testing machines, impact specimen notch pulling beds, impact specimen notch projectors, low temperature tanks, and the following detailed introduction was made by the technical staff of Jinan Hengsi Shengda Instrument Co., Ltd.:

Each impact must be applied to the normal deviation of the battery surface. The pressure tester will achieve such acceleration when each impact of the battery, that is, at the initial 3ms, the small uniform acceleration is 75g (g is the local gravity acceleration). The peak acceleration should be between 125g and 175g. The battery should be subjected to experiment at 20±5°C (68±9°F). Impact experimental machine is a fine test instrument that determines the mechanical functions, process functions, internal defects and checks the dynamic trade-offs of torsional components under various premises and conditions. In order to ensure the precise dimensions of the notch, the notch should be processed by impact specimen notch bedding, requiring the notch bottom to be lubricated and there are no marks parallel to the notch axis. Also, the preparation of the sample should also prevent the impact function due to work hardening or overheating. In order to meet the needs of broad users and reduce the hardships in the sample preparation process, especially the hardships in the sample gap manufacturing process, impact testing machine (recommended: impact testing machine) We have developed and developed this special pulling bed based on the experiences of various advanced predecessors in this field in this field.

Impact testing machineIt is a double knife structure with hydraulic transmission. No matter whether you process the V-shaped notch, you still need to change the tool. The sample notch only takes 18 seconds to process it at one time, and the operation is simple and reliable. Because of the principle of single-brushing and forming, its processing uniformity is excellent and can guarantee that the sample gaps processed can pass 100%. The impact experiment machine is a new impact experiment machine that can instantly measure and record the characteristic curves of data during the impact process. After changing the pendulum and sample base, this machine can complete the experiments of two methods: simple support beam and cantilever beam. When the specimen that was impacted by the impact experiment machine was impacted by the hammer, the signal of the signal was generated by the high-speed load measurement sensor. After being expanded by the high-speed expander, it was quickly converted into a digital signal from A/D to the computer for data processing, and it was also sent to the computer for data processing by detecting the angular displacement signal, with high accuracy. Impact testing machines are mainly used to test mechanical function objectives of various metals, non-metals and composite materials.
