Work Experience
| Jun. 2011 - Sept. 2021 | China Automotive Technology and Research Center (CATARC), Automotive Engineering Research Institute. |
| 2012 - 2019 | Road Simulation. Team Leader. |
| I founded two Road Simulation teams, 4-poster and Spindle-Coupled road simulation, while building the standardized iterative operation workflows. I turned the testing teams over to my teammate in 2019. These two business units consistently contributing revenue of twenty million RMB annually. Our main cooperation partners are Honda, FCA, and Daimler AG. | |
| 2012 - 2014 | Road Load Data Acquisition (RLDA) and Data Analysis. Team Leader. |
| I founded an RLDA team to cultivate our technical expertise in instrumentation, polarity check, strain gauge application, calibration, and on-the-site troubleshooting. I handed the testing team over to my teammate in 2014, this unit has been consistently contributing revenue of six million RMB each year. | |
| Expertise in up to 200 channels simultaneously data collection against the MIL-STD working condition and ensured data quality. | |
| We developed a serial of three-component load cells based on strain gauge with the crosstalk coupling between channels being less than 3%. The finished product reaching 10 kN and 70 kN of capacity can be equipped in various parts on a vehicle, including chassis sub-frame and engine mounting. |
| 2011 - 2012 | Vehicle Dynamics Testing. Test Development Engineer. |
| Configured various instruments and sensors and established standard testing procedures under the ISO/SAE/GB/OEM to fulfill clients’ demands. Executed data processing and programmed efficient pipeline by nCode, FlexPro, and VBA to meet the signal processing requirements. Contributed to the road testing capability based on vehicle dynamics, set up a corresponding team, handed the instruments and knowledge to colleague in 2012. | |
| Dec. 2018- Present | XERUS Engineering Technology, Founder. |
Projects
| 2020 | Side Impact Test Rig, Principle Designer |
| We cooperated with Mechatronic Vehicle Systems Lab at the University of Waterloo to propose a PLC-driven test rig that could introduce predefined energy into the wheel-suspension assembly for the Daimler Greater China Ltd RD Tech Center China. The proposed system was composed of a pendulum, an adjustable pendulum head, and a Beckhoff PLC system control impact energy by changing impact weight, releasing height, and triggering impact force measurement in one second. The up-to-one-ton moving pendulum triggered a high-speed light curtain, and the 30 channels of acceleration and force between the pendulum system and the specimen could be simultaneously collected–the complete process is less than one second. | |
| 2019 | Air Spring Controller, Researcher |
| Employed the Siemens S7-200 PLC, compressed air pump, and proportional air valve to construct an air suspension ride height-adjusting system for Daimler AG’s prototype vehicle. Enabled the system to adjust the vehicle’s ride height to a designated value only within 5 seconds. | |
| 2018 - 2020 | Wheel Force Prediction Algorithm, Researcher |
| Discovered the strong coherence between wheel hub acceleration and wheel force by frequency response function. Programmed a real-time convolution pipeline to predict wheel force via Python. Investigated in black-box modelling by multilayer perceptron and Long short-term memory. | |
| 2019 | HSRC Technology, Researcher |
| Developed iterative technology grounded on virtual Road Load Data Acquisition and Hybrid Simulation Response Convergence (HSRC) with adopting the self-developed strain gauge three-component load cell as the feedback signal of suspension in iteration, and capitalizing on HSRC to integrate real physical models, virtual FTire model, with the digital road to calculate drive file. | |
