Publication number: 20240082966Abstract: A cross-coupling control method for moving beam of gantry machine tool is disclosed, which relates to the technical field of CNC machine tool control. The cross-coupling control method includes: Step 1: establishing a crossbeam dynamics model considering a ram on the crossbeam, and at the same time simplifying the model for an observer design; step 2: realizing a PID control parameter adjustment of motors at both ends in accordance with a method of parameter tuning of a unilateral servo control system; using a servo system with the same control parameters to jointly drive the crossbeam up and down, realizing the synchronous control and realizing PID control parameter tuning for both end motors. The disclosure not only reduces the synchronization error caused by the torsion of the crossbeam, but also solves the synchronization error caused by the asymmetric load on both sides, and improves the system robustness and stability.Type: ApplicationFiled: November 14, 2023Publication date: March 14, 2024Inventors: Chuanhai Chen, Zhifeng Liu, Jinyan Guo, Tongtong Jin, Xinyuan He, Shuo Zhao, Baobao Qi, Chunshi Liu, Zhaojun Yang, Zhijie Li, Chunlei Hua, Liang Zhang, Haoming Yan

Patent number: 7216924Abstract: An automotive vehicle comprises a frame having a pair of side rails interconnected by a plurality of cross members. A rocker panel substantially parallel to and spaced from each side rail creates a gap. An energy transfer member seats within the gap for transferring energy between the rocker panel and the side rail in a side impact event. The energy transfer member is sufficiently stronger than the side rail such that impact energy deforms the rocker panel and travels through the energy transfer member to deform the side rail prior to any deformation of the energy transfer member, thereby maintaining the gap to reduce side structure intrusion into an occupant compartment. An accelerometer mounted within the vehicle inboard of the side rails senses vehicle frame acceleration, and activates a vehicle airbag system as necessary.Type: GrantFiled: October 21, 2004Date of Patent: May 15, 2007Assignee: General Motors CorporationInventors: Haoming Li, Bryan J.
