针对柴油机曲轴轴承磨损故障信号特征微弱,易被噪声湮没且不同故障程度信号较难区分的特点,提出了一种基于压缩小波和局部保持投影的柴油机信息熵增强方法。利用压缩小波对信号多尺度重构减弱噪声干扰,通过局部保持映射对多尺度信号进行降维,消除冗余信息并增强信号的冲击特性,最终以时域、频域以及时频域的三种信息熵表征信号特征。仿真和实例信号表明,该方法对故障信号特征增强明显,依据信息熵值实现了曲轴磨损状态的分类识别。

In the past few decades, much effort has been devoted to estimate accurate protein-ligand binding affinity, which is a central challenge in structure-based drug *** the equilibrium free energy estimators, such as free energy perturbation（FEP） method, thermodynamic integration（TI） method,Bennett’s acceptance ratio（BAR） and so on, require that molecular dynamic simulations at each states including many immediate states reach equilibrium and the structure sampling is uncorrelated. These need a large computational cost to get the converged free energy calculations. Rather than spending large computational costs on long equilibrium sampling, in 1997,Jarzynski put forward an equality to calculate the free energy difference between the two states, which needed to carry out many shorter nonequilibrium simulations from state A to state ***, in contrast to equilibrium free energy calculations, how the performance of the nonequilibrium free energy calculations in the relative binding free energy calculations is not clear *** known complex systems with respective different ligands are chosen to calculate the relative binding affinity for comparing the performance of nonequilibrium and equilibrium *** is T4-lysozyme mutant L99A（L99A） system. Another one is cyclooxygenase-2（COX-2） system.

基于时频相干分析的曲轴主轴承磨损故障诊断研究

第十五届全国化学动力学会议

作者： Pengfei Li Meiting Wang xiangyu jia 梅晔 State Key Laboratory of Precision Spectroscopy School of Physics and Materials ScienceEast China Normal University CNYU-ECNU Center for Computational Chemistry at NYU Shanghai

Free energy calculations at high levels such as QM（ai）/MM level are very expensive, due that extensive phase space sampling is always indispensable before the convergence can be reached and for most cases many intermediate states are required to make the conversion between two states smooth enough. We proposed an efficient method for the calculations of free energies at QM/MM levels. In this method, the QM/MM free energies are computed indirectly via a series of MM states and the MM-to-QM corrections were computed at two end points using thermodynamics perturbation（TP）. This method provides the minimal variance for the results if expensive QM/MM simulations are avoided. We also proposed a quantity called reweighting entropy, which measures the reliability of TP calculations. Similarly, calculations of potentials of mean force（PMF）, which are essential to the understanding of reaction mechanisms, are also expensive. We also proposed an efficient method for the calculations of PMF at high QM/MM levels using phase space sampling under low level Hamiltonians followed by free energy corrections.

关键词： free energy potential of mean force QM/MM WHAM TP
