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《带抗扭转结构的柔性直线导轨》（"A flexure-based linear guide with torsion reinforcement structures"，编号JMR-21-1127）的配套实测与建模数据。本实验的核心目标为验证SPACAR模型（SPACAR）所预测的该直线导轨固有频率。实验中将该直线导轨安置于其运动行程（Z向）内的不同位置，在每个位置处通过手持激振锤施加激励，并采用激光多普勒测振仪采集振动信号，由此为运动行程内的每个位置生成一组对应数据集（以文本文件形式存储），每行数据分别记录直线导轨在运动行程中的位置参数与振动速度值。通过快速傅里叶变换（Fast Fourier Transform, FFT）将时域振动数据转换至频域，更多实验细节可参阅该论文。数据后处理环节采用配套的MATLAB脚本完成，该脚本可自动生成论文中所用的相关图表。若需打开建模数据，需使用特温特大学（University of Twente）开发的SPACAR软件（SPACAR）。SPACAR仿真工作由Mark Naves完成，实验测量与后续数据处理由Jelle Rommers负责。
