Past Research
[1] Title: In-machine measurement motion simulation based on multi-axis CNC machine tools Mar 2019- Apr 2020
Project Lead, Sponsored by Dalian University of Technology, No. 2019101410501040851, (funding: 1000 RMB)
- Personal Work: Aiming at the kinematics simulation of the in-machine measurement process, based on UG, the model of multi-axis machine tool was established and the contact probe model was integrated. Then the workpiece model with the complex surface was built, and G code was generated automatically. The results showed that the generated G code can simulate the motion of the probe well.
[2] Title: Large-area surface roughening method for high-performance adhesive bonding Apr 2023 - Date
Participant, Sponsored by National Youth Science Foundation of China, No.52205449
- Personal Work [1]: Targeting challenging issues, such as low grinding efficiency, poor consistency and ambiguous relationship between adhesive strength and the surface topography of the Co-Bottom Component surface, an adhesive experiment was designed. Through simulation and experimental analysis, the influences of roughness and texture direction on the adhesive strength of aluminium alloy and composite materials were determined.
- Personal Work [2]: A machining strategy is proposed utilizing the pneumatic control grinding head and KUKA industrial robot. Based on the abrasive kinematics, dynamics and MATLAB, the abrasive motion trajectory is analyzed, and the robot grinding surface prediction model is established.
- Personal Work [3]: The large-area grinding software of the robot is developed based on C++, which can automatically generate the machining trajectory according to the theoretical profile of the Co-Bottom Component.
[3] Title: Milling and finishing of liquid rocket engine nozzle cooling channel Dec 2022 - Mar 2023
Participant, Sponsored by China Academy of Space Technology, No.320UT-Z-202
- Personal Work: Aiming at the problem of removing burrs in liquid rocket engine cooling channel. The flexible grinding scheme for deburring was developed, and the platform was built. A deburring software of the KUKA robot was written based on C++. The results show that the scheme is more efficient than before.
[4] Title: Precision machining mechanism of large feed array with high-performance Sep 2021 - Nov 2022
Participant, Sponsored by National Natural Science Foundation of China, No.U20B2033
- Personal Work: To address the machining problem of space-borne antenna feed array, the electromagnetic coupling model of feed cup machining error (roundness error and position error) is established based on the electromagnetic field theory and geometrical theory of diffraction. In terms of antenna electrical performance (such as gain, beamwidth, etc), the error sensitivity of the feed cup and feed array at different frequencies were analyzed.
