Recently, the Hunan Provincial Department of Science and Technology organized experts to convene an acceptance meeting for the province's top ten technological research projects. The project "Digital Prototype and Twin Technology Research for Rotary Drilling Rigs," led by Sunward Intelligent Equipment, successfully passed acceptance. Attendees included the Frontier Technology Division, the Supervision, Evaluation and Research Integrity Division, and the Project Operation Service Department of the Provincial Science and Technology Affairs Center of the Hunan Provincial Department of Science and Technology, the Major Special Projects Division of the Changsha Municipal Science and Technology Bureau, relevant heads of the project unit, and review experts. He Qinghua, founder, chief expert, and project leader of Sunward Intelligent Equipment, and Zhu Jianxin, deputy general manager and project task leader, attended the meeting.

The acceptance meeting was chaired by Zhang Tianjiao, a second-level researcher of the Supervision, Evaluation and Research Integrity Division of the Provincial Department of Science and Technology. Zhu Jianxin, deputy general manager and project task leader of Sunward Intelligent Equipment, attended the meeting and introduced the project team members present. He Songquan, dean of the Common Technology Research Institute of Sunward Intelligent Equipment and project task leader, gave a detailed report on the project's completion. The acceptance expert panel listened carefully to the project report, conducted an on-site inspection of the prototype demonstration of the results, carefully reviewed the acceptance materials, and questioned the project results. Finally, the expert panel fully affirmed the project results.

The attending experts unanimously agreed that the project "Digital Prototype and Twin Technology Research for Rotary Drilling Rigs" achieved breakthroughs in energy-saving technology for potential energy recovery and reuse of the main winch based on digital prototypes, and in energy flow analysis and formation identification during drilling based on twin models. It consolidated the unit's technical advantage in the field of rotary drilling rig products and played a promoting role in the industry's development.

At the meeting, Dr. Ma Yiwei of the Frontier Technology Division of the Hunan Provincial Department of Science and Technology affirmed the research results of the project team; at the same time, he also hoped that Sunward Intelligent Equipment would continue to reserve technologies and products in the field of construction machinery and continuously improve the company's innovation capacity.

Finally, He Qinghua, founder, chief expert, and project leader of Sunward Intelligent Equipment, expressed gratitude for the guidance of the leaders and experts. He Qinghua stated that the promotion and application of key technologies such as digital twins from this project should be strengthened in other construction machinery products, contributing to the high-quality development of China's engineering equipment.
