Development of an H reduction and moderate oxidation method for 3,5-dimethylpyridine hydrogenation in

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 12,   Pages 1807-1817 doi: 10.1007/s11705-022-2243-2

Abstract: Under the same reduction conditions (300 °C in H2), the catalytic activity of the non-in-situ reduced Ru/C-n catalyst was higher than that of the in-situ reduced Ru/C-y catalyst.Therefore, an in-situ H2 reduction and moderate oxidation method was developed to increaseThe developed in-situ H2 reduction and moderate oxidation method eliminated the stepof the non-in-situ reduction of catalyst outside the trickle bed reactor.

A novel six-legged walking machine tool for

Frontiers of Mechanical Engineering 2020, Volume 15, Issue 3,   Pages 351-364 doi: 10.1007/s11465-020-0594-2

Abstract: The manufacture and maintenance of large parts in ships, trains, aircrafts, and so on create an increasing demand for mobile machine tools to perform operations. However, few mobile robots can accommodate the complex environment of industrial plants while performing machining tasks. This study proposes a novel six-legged walking machine tool consisting of a legged mobile robot and a portable parallel kinematic machine tool. The kinematic model of the entire system is presented, and the workspace of different components, including a leg, the body, and the head, is analyzed. A hierarchical motion planning scheme is proposed to take advantage of the large workspace of the legged mobile platform and the high precision of the parallel machine tool. The repeatability of the head motion, body motion, and walking distance is evaluated through experiments, which is 0.11, 1.0, and 3.4 mm, respectively. Finally, an application scenario is shown in which the walking machine tool steps successfully over a 250 mm-high obstacle and drills a hole in an aluminum plate. The experiments prove the rationality of the hierarchical motion planning scheme and demonstrate the extensive potential of the walking machine tool for operations on large parts.
