A MODULAR, AUTOMATIC, MODAL IMPACT HAMMER - EXPERIMENTAL VALIDATION

Raw and calculated data from the repeatbility, single impact and force adjustment testing of the devloped automatic impact hammer at the University of Technology vibration lab. UTS required a hammer greater than the SAM-1 by NV tech that could measure force reposnses greater than 200N. The developed hammer uses a manual hammer in place of a connected arm that clamps into a rotor connected to the motor, allowing the hammer arm to be fully interchangeable depending on the hammer required for experimentation. The following data was conducted using the B & K 8206 hammer and measured against a test piece of steel. Impact hammer testing was conducted on a test block made of steel. Results were measured using the Keysight InfinilVision DSOX2004A Digital storage oscilloscope. To ensure that the signal was optimal for data processing a signal conditioner was connected between the two. The 4114B1 Dytran model was used. Velocity of hammer swing was the only factor changed throughout testing signified by eith 9000, 30000, 100000. The data set contains both raw data and calculated data, at different velocities. also contains comparison with the NV Tech Sam1 hammer (only in the form of PNG files).

本数据集为某理工大学振动实验室中，自研自动冲击锤（automatic impact hammer）的重复性测试、单次冲击测试与力调节测试所产生的原始数据与计算后数据。UTS要求研发一款性能超越NV Tech出品的SAM-1的冲击锤，以实现200牛以上的力响应测量。该自研冲击锤采用手动锤体替代了原本的连接臂——该连接臂可夹持于与电机相连的转子上，使得锤臂可根据实验需求完全更换为适配型号。本次测试采用B&K 8206型冲击锤，以钢制试件为测试对象，在钢制测试块上开展冲击测试，测试结果通过是德科技（Keysight）InfinilVision DSOX2004A型数字存储示波器采集。为确保信号满足数据处理的最优条件，测试系统中接入了型号为4114B1的Dytran信号调理器。本次测试仅改变锤体挥摆速度这一变量，以9000、30000、100000这三组参数分别标识不同工况。本数据集不仅包含不同挥摆速度下的原始数据与计算后数据，还包含与NV Tech出品的SAM-1冲击锤的对比数据（仅以PNG格式文件提供）。其中，自研冲击锤又名AMI（黄色款），NV Tech出品的SAM-1又名SAM（蓝色款）。
