| 1 | Structural Topology and Dynamic Response Analysis of an Electric Torque Vectoring Drive-Axle for Electric Vehicles显示文摘In-wheel motor-drive electric vehicles have the advantage of independently controllable wheel torque and the disadvantages of unsprung mass rise and power restriction.To address the disadvantages,a centralized layout electric torque vectoring drive-axle system(E-TVDS)with dual motors is proposed,which can realize arbitrary distribution of driving torque between the left and right wheels.First,the speed and torque distribution principle of E-TVDS based on velocity diagram are analyzed,and a virtual prototype of the whole vehicle with basic gear ratio relation model of the E-TVDS is built for simulation to verify the theoretical results and the basic effect of E-TVDS on the steering performance of the vehicle.Second,the charac-teristics of 36 types of the novel E-TVDS topology structure are compared and analyzed,and the optimal structure scheme is selected.Third,the accurate multiple degrees of freedom dynamic model for the optimal structure is established by using the bond graph method,and its dynamic response characteristics are analyzed.The results show that the vehicle equipped with the proposed E-TVDS can distribute the driving torque with the almost identical amount but opposite sign between the left and right wheels in any direction,and varying amount according to different chassis dynamics control requirements,and the torque response performance is great with little delay and overshoot.The function and dynamic response of the proposed E-TVDS show that it has potential application value for various performance improvements of electric vehicles. | Junnian Wang Shoulin Gao Yue Qiang Meng Xu Changyang Guan Zidong Zhou | 2022 | Automotive Innovation2022，5，2： | 1 |
| 2 | Mid-infrared all-optical modulators based on an acetylene-filled hollow-core fiber显示文摘We report all-optical mid-infrared phase and intensity modulators based on the photo-thermal effect in an acetylene-filled anti-resonant hollow-core fiber.Optical absorption of the control beam promotes the gas molecules to a higher energy level,which induces localized heating through non-radiative relaxation and modulates the refractive index of the gas material and hence the accumulated phase of the signal beam propagating through the hollow-core fiber.By modulating the intensity of the control beam,the phase of the signal beam is modulated accordingly.By use of a 1.53μm near-infrared control beam,all-optical phase modulation up to 2.2πrad is experimentally demonstrated at the signal wavelength of 3.35μm.With the phase modulator placed in one arm of a Mach-Zehnder interferometer,intensity modulation with on-off ratio of 25 dB is achieved.The gas-filled hollow-core-fiber modulators could operate over an ultra-broad wavelength band from near-to mid-infrared and have promising application in mid-infrared photonic systems. | Kaiyuan Zheng Shoulin Jiang Feifan Chen Yan Zhao Shoufei Gao Yingying Wang Hoi Lut Ho Wei Jin | 2022 | Light(Advanced Manufacturing)2022，3，4： | 0 |
| 3 | Broadband all-fiber optical phase modulator based on photo-thermal effect in a gas-filled hollow-core fiber显示文摘We report broadband all-fiber optical phase modulation based on the photo-thermal effect in a gas-filled hollow-core fiber.The phase modulation dynamics are studied by multi-physics simulation.A phase modulator is fabricated using a 5.6-cm-long anti-resonant hollow-core fiber with pure acetylene filling.It has a half-wave optical power of 289 mW at 100 kHz and an average insertion loss 0.6 dB over a broad wavelength range from 1450 to 1650 nm.The rise and fall time constants are 3.5 and 3.7μs,respectively,2–3 orders of magnitude better than the previously reported microfiber-based photo-thermal phase modulators.The gas-filled hollow-core waveguide configuration is promising for optical phase modulation from ultraviolet to mid-infrared which is challenging to achieve with solid optical fibers. | Shoulin Jiang Feifan Chen Yan Zhao Shoufei Gao Yingying Wang Hoi Lut Ho Wei Jin | 2023 | Opto-Electronic Advances2023，6，5： | 0 |
