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.

文章《带抗扭增强结构的柔性直线导轨》（JMR-21-1127）的测量与建模数据。本实验旨在验证SPACAR模型（SPACAR model）预测的直线导轨固有频率（eigenfrequencies）。直线导轨在其运动范围（Z方向）内的不同位置进行布置；每个位置处，采用移动锤（roving hammer）激励导轨，振动则通过激光多普勒设备（laser doppler device）测量。每个位置对应生成一个数据集（以文本文件形式存储，包含两行数据：一行记录直线导轨在运动范围内的位置，另一行记录振动速度）。通过FFT变换（FFT transform），这些数据被转换至频域。更多细节可参见该文章。后处理通过所提供的Matlab脚本（Matlab script）完成，该脚本可自动绘制文章中的图表。建模数据需使用荷兰屯特大学（University of Twente）的SPACAR软件（SPACAR software）打开。SPACAR模拟由Mark Naves完成，测量及后处理工作则由Jelle Rommers负责。
