Imaging the western boundary of the Sichuan Craton from multiple geophysical observations

The boundary between the cratonic and orogenic lithospheres is one of the most significant seismogenic zones characterized by strong lithospheric deformation. As the essential tectonic block bounding the eastern Tibetan Plateau， the Sichuan Craton (SCC) resists the eastward escape of Plateau’s crustal materials， resulting in the uplift of the Songpan-Ganzi Block (SGB) and the crustal deformation of the Longmenshan tectonic belt (LMTB). To uncover the compressional structures and deformational mode of the LMTB and SCC， it is crucial to determine the precise location and geometry of the western boundary of the SCC. To address this issue， the lithospheric properties of the obduction SGB， the underthrusting SCC， and the LMTB were analyzed using a series of geophysical data， including seismic reflection profiles， magnetotellurics， aeromagnetics， gravity， and seismic tomography. The crust of the SGB is characterized by low magnetism， low seismic velocity， low resistivity and low Bouguer gravity， while that of the SCC features non-uniform high magnetism， high seismic velocity， high resistivity and high Bouguer gravity. The LMTB， as the boundary between the SGB and SCC， shows the geophysical characteristics similar to the SCC along the southern and central segments. The integration of all these geophysical observations suggests that the SCC’s western boundary follows the Yingxiu-Beichuan fault along the northern segment， without obvious underthrust. However， this boundary is located west of the Wenchuan-Maoxian fault zone along the southern and central segments， with distinct westward wedging/underthrusting. The irregular geometry of the SCC’s western boundary can further explain the variation in structural deformation along the LMTB. By comparing the differences in crustal thickness and lithospheric strength between the SGB and SCC， this study suggests that the varying crustal strength between tectonic blocks may be the controlling factor for the irregular geometry of the

在2024年年底之前,将有4人登上航天器,飞往月球、绕月之后再返回地球。是的,曾经去过,曾经做过。但那已经过去50多年了。美国国家航空航天局的“阿尔忒弥斯二号”任务是2025年登月计划的热身,这将标志着自1972年“阿波罗17号”任务以来,美国首次有宇航员离开近地轨道。“这表明,美国正在恢复已失去几十年的技术能力,正在计划让宇航员重返月球。”英国莱斯特大学副教授布莱丁·鲍文(Bleddyn Bowen)说,“经过几十年的概念艺术、含糊其词的承诺、总统和国会的犹豫不决,现在看到一次真正的载人绕月任务,确实令人振奋。”

Implementation of Fuzzy Logic Control into an Equivalent Minimization Strategy for Adaptive Energy Management of A Parallel Hybrid Electric Vehicle

引用

Journal of Transportation Technologies 2024年第1期14卷 88-118页

作者： Jared A. Diethorn andrew C. Nix Mario G. Perhinschi W. Scott Wayne Department of Mechanical and Aerospace Engineering West Virginia University Morgantown WV USA

As government agencies continue to tighten emissions regulations due to the continued increase in greenhouse gas production, automotive industries are seeking to produce increasingly efficient vehicle technology. Hybrid electric vehicles (HEVs) have been introduced to mitigate problems while improving fuel economy. HEVs have led to the demand of creating more advanced controls software to consider multiple components for propulsive power in a vehicle. A large section in the software development process is the implementation of an optimal energy management strategy meant to improve the overall fuel efficiency of the vehicle. Optimal strategies can be implemented when driving conditions are known a prior. The Equivalent Consumption Minimization Strategy (ECMS) is an optimal control strategy that uses an equivalence factor to equate electrical to mechanical power when performing torque split determination between the internal combustion engine and electric motor for propulsive and regenerative torque. This equivalence factor is determined from offline vehicle simulations using a sensitivity analysis to provide optimal fuel economy results while maintaining predetermined high voltage battery state of charge (SOC) constraints. When the control hierarchy is modified or different driving styles are applied, the analysis must be redone to update the equivalence factor. The goal of this work is to implement a fuzzy logic controller that dynamically updates the equivalence factor to improve fuel economy, maintain a strict charge sustaining window of operation for the high voltage battery, and reduce computational time required during algorithm development. The adaptive algorithm is validated against global optimum fuel economy and charge sustaining results from a sensitivity analysis performed for multiple drive cycles. Results show a maximum fuel economy improvement of 9.82% when using a mild driving style and a 95% success rate when maintaining an ending SOC within 5% of th
