University Exhibition Area of ​​the 26th Industrial Expo: Domestic wind power bearings, embodied robots and new varieties of river crabs unveiled

China News Service, Shanghai, September 29 (Reporter Chen Jing) Fully autonomous humanoid electric body-operated working robots, a full-chain localization plan for large-scale wind power main bearings, and a new strain of Chinese mitten crab "White Jade Crab"... These are the innovation achievements of universities that will be unveiled at the university exhibition area of ​​the 26th China International Industrial Expo (hereinafter referred to as the "Industry Expo"). On the 29th, the reporter visited a number of universities in Shanghai and got close to the scientific research teams and their results.

At the Shanghai Institute of Electrical Engineering, the reporter learned that the wind power main bearing is called the "core joint" of the wind turbine, carrying all the load of blade rotation. Once it fails, the whole machine will be shut down, and the maintenance cost is often dozens of times that of the bearing itself. "Insufficient reliability, substandard lifespan, and frequent abnormal failures" have always plagued enterprises in China's wind power industry chain.

Today, these problems have been solved by the intelligent design and manufacturing team of high-end transmission systems of Shanghai Institute of Electric Power - a set of localization solutions covering the entire chain of design, process, verification and application, giving the "big country's important equipment" an independent and controllable "Chinese joint". According to Associate Professor Gao Xuehai, the leader of the scientific research project team, it is not a "paper breakthrough" in the laboratory, but a solution that "grows" out of wind farm failures.

The team broke the tradition of "only designing bearings" and raised the perspective to "designing shaft systems", viewing the wind turbine transmission chain as an organic whole. Bearings are no longer isolated parts, but system links that work together with blades, main shafts and gearboxes. In long-term industry-research cooperation, the scientific research team has accumulated a set of wind turbine bearing design knowledge and failure mode libraries covering hundreds of scenarios, upgrading from "only evaluating raceways" to coupling analysis of all elements. This "whole machine-component" collaborative design idea allows bearings to shift from "passively adapting to the whole machine" to "actively optimizing the system."

It is reported that the key performance indicators of this full-chain solution are fully benchmarked against similar international products, and the cost is more than 30% lower than imported products. The supply cycle is compressed from 8 months to 4 months, so that the complete machine factory no longer has to "wait for rice to be ready" during the rush installation window period.

It is understood that places such as substations and distribution rooms are densely equipped with equipment, and some operations involve high voltages, which impose strict restrictions on on-site space and safety distances. In order to prevent personnel from approaching dangerous sources, the scientific research team of Shanghai Electric Power University developed a humanoid electric embodied working robot.

The school's scientific research team told reporters that at this industry expo, the team will focus on demonstrating the VR remote operation function of the robot. The reporter saw that when the operator puts on VR glasses and holds a controller, he can control the robot's arms through the movement of the handle and changes in posture. According to reports, this intuitive control method allows the operator to adjust the position and posture of the arms according to task needs. Through the teleoperation function, workers can remotely participate in tasks and adjust or stop actions according to actual conditions, providing a feasible path for robots to gradually assume power operation tasks.

At Shanghai Ocean University, the new strain of Chinese mitten crab "White Jade Crab" bred by Professor Wu Xuqian's team from the School of Fisheries and Life Sciences has attracted much attention. At present, this achievement has entered the industrialization stage and will be launched in large quantities in October.

It is understood that after ten years of genetic selection, the team has obtained a new strain of hairy crabs with shell colors, filling the gap in domestic hairy crab color crab varieties. It is reported that the white shell color is genetically stable, the meat is fresher and sweeter, and the crab roe and crab paste are visible to the naked eye.

It is reported that after successive generations of purification, the team has been continuously breeding to the fifth generation and found the control genes and molecular markers of white-shell crabs. The team found that the reason why the white jade crab is so white is that the crab shell lacks astaxanthin and beta-carotene, while the content of astaxanthin, beta-carotene and zeaxanthin in its crab roe is not significantly different from that of ordinary green-shell crabs; the white jade crab has a higher content of umami and sweet substances, achieving the unity of "good-looking" and "delicious". This year, the team signed authorization use and achievement transformation agreements with 8 companies, with a total contract value of 5.1 million yuan.

At Shanghai Maritime University, the school’s research team built a port digital twin intelligent simulation decision-making platform, innovatively constructed a three-in-one autonomous and controllable technology architecture of “twin base-agent cluster-realistic verification” to realize the integrated upgrade of port operations, energy efficiency management and control, and intelligent decision-making, and provide new domestic technology solutions for the green, efficient, and self-evolving development of smart ports. The platform innovatively creates a multi-agent collaboration system driven by AI Agent, and builds an intelligent operation matrix with two-way coverage of scenarios and equipment. It is reported that various types of intelligent agents can interact with data in real time, perform dynamic collaborative scheduling, and make independent judgments and decisions, replacing the traditional manual scheduling model and completing the entire process independently.
