Chun-Hsing HO,María Francisca Martínez GONZÁLEZ,Cristina Pilar Martín LINARES

Frontiers of Structural and Civil Engineering 2017, Volume 11, Issue 1,   Pages 1-7 doi: 10.1007/s11709-016-0367-5

Abstract: The objective of this research is to evaluate an impact of asphalt mixture beams with varying sizes ofthat the size of the aggregate may affect the test’s results; the other concern is that such small beamsAsphalt thin beams prepared with three different nominal maximum aggregate size (NMAS) (12.5mm, 9.5 mmdifferences among the three NMAS specimens are not significant, meaning that the impact of asphalt thinbeams prepared with the three NMAS on the prediction of thermal cracking is minimal and can be neglected

Position-varying surface roughness prediction method considering compensated acceleration in milling of thin-walled

Frontiers of Mechanical Engineering 2021, Volume 16, Issue 4,   Pages 855-867 doi: 10.1007/s11465-021-0649-z

Abstract: Machined surface roughness will affect parts’ service performance. Thus, predicting it in the machining is important to avoid rejects. Surface roughness will be affected by system position dependent vibration even under constant parameter with certain toolpath processing in the finishing. Aiming at surface roughness prediction in the machining process, this paper proposes a position-varying surface roughness prediction method based on compensated acceleration by using regression analysis. To reduce the stochastic error of measuring the machined surface profile height, the surface area is repeatedly measured three times, and Pauta criterion is adopted to eliminate abnormal points. The actual vibration state at any processing position is obtained through the single-point monitoring acceleration compensation model. Seven acceleration features are extracted, and valley, which has the highest R-square proving the effectiveness of the filtering features, is selected as the input of the prediction model by mutual information coefficients. Finally, by comparing the measured and predicted surface roughness curves, they have the same trends, with the average error of 16.28% and the minimum error of 0.16%. Moreover, the prediction curve matches and agrees well with the actual surface state, which verifies the accuracy and reliability of the model.
