Data underlying the publication: A flexure-based linear guide with torsion reinforcement structures

Measurement and modeling data for article "A flexure-based linear guide with torsion reinforcement structures", JMR-21-1127. The goal of the experiment is to verify the eigenfrequencies of the linear guide predicted by the SPACAR model. The linear guide is set up at different positions in its motion range (Z-direction). At each position, it is excited with a roving hammer and the vibrations are measured with a laser doppler device. This results in a dataset for each position in the motion range (these are the text documents, containing two rows, one for position of the linear guide in its motion range and one for the vibration velocity). Using an FFT transform, this data is converted to the frequency domain. More details can be found in the article. Postprocessing is done using the provided Matlab script (the script automatically plots the figures from the article). To open the modelling data, you need the SPACAR software from university of Twente. The SPACAR simulation is done by Mark Naves and the measurements are carried out and postprocessed by Jelle Rommers.本数据集为论文《带抗扭加强结构的柔性直线导轨》（"A flexure-based linear guide with torsion reinforcement structures"）的配套测量与建模数据，论文编号为JMR-21-1127。本实验的核心目标为验证SPACAR模型所预测的该直线导轨的固有频率。实验中将直线导轨安置于其运动行程（Z向）内的多个不同位置，在每个位置处采用漫游激振锤进行激振，并通过激光多普勒振动测量装置采集振动信号。由此可得到运动行程内各位置对应的数据集：所有数据集均采用文本文档格式存储，包含两行数据，第一行记录直线导轨在运动行程中的位置参数，第二行记录振动速度数值。通过快速傅里叶变换（FFT）将原始数据转换至频域。更多实验细节可参阅该论文。数据集的后处理可通过附带的Matlab脚本完成，该脚本可自动生成论文中所需的相关配图。若需读取建模数据，需使用特温特大学（University of Twente）开发的SPACAR软件。本次SPACAR仿真工作由Mark Naves完成，振动测量与后处理工作由Jelle Rommers执行。
