Electric car brakes using smart materials, IoT applications for forest monitoring… are studies on sustainable production that Vietnamese scientists share with international scholars.
The research results were shared at the 20th global conference on sustainable production (GCSM 2024) held from October 9 – 11 in Binh Duong with the participation of 200 domestic and international scientists divided Share more than 100 studies on sustainable products, materials, processes, and production systems.
Research aims to reduce the use of fossil energy sources, promote the application of new energy sources, new materials, technologies to combat climate change, and develop green economy in life and production.
At the conference, a group of authors from Viet Duc University and Ho Chi Minh City University of Industry shared research on types of brakes installed in electric cars using smart materials to help increase the driving experience for drivers. PhD student Nguyen Duy Hung (Viet Duc University) said that compared to gasoline cars, electric car steering wheels provide less driving sensation. Specifically, when cornering, the steering wheel of an electric car does not have a certain weight like a gasoline car. According to the research team, steering feel is very important to help the driver feel the steering angle based on the weight of the steering wheel to control the vehicle through difficult terrain.
From this fact, the team created a magnetic brake box installed on the electric vehicle’s steering system. Magnetic brakes feature smart compounds created from metal magnetic fluids and catalytic additives. When the current passing through the brake is greater, it will create a large force transmitted to the steering wheel to create the necessary heaviness to help increase the driving feeling for the driver.
“The magnetic brake system helps electric car drivers have the same steering feel as a gasoline car, helping them control the car better,” Hung said. The team’s research is in the stage of simulating and calculating magnetic braking operations on the two front drive axles. In the near future, the team will develop this braking system on all four drive axles and test it for drivers to use for evaluation. The group aims to apply this magnetic braking system to major electric vehicle manufacturers today.
The research team at FPT University Ho Chi Minh City campus introduces an IoT system that warns of risks of fire, flash floods, landslides… in the forest in real time. The system uses temperature, soil moisture, air humidity and precipitation sensors to collect data. This data source is collected and managed by software in the form of a website or mobile application. When the indicators exceed the prescribed threshold, the system issues a warning of forest fire risk to managers for timely handling. This system is evaluated by the team as low cost, simple to operate but provides accurate, real-time data for effective forest monitoring.
At the conference, many studies by international scientists on sustainable production received much attention from the community. The author group of Karlsruhe Institute of Technology (Germany) shares research on electric motor parts made of recycled, environmentally friendly materials. This institute scientist also proposed technologies to recycle used hydrogen fuel cells, contributing to the development of circular economy.
Next, a scientist from Cranfield University (UK) introduced research on optimizing aircraft manufacturing stages to help save costs and raw materials…
Dr. Ha Thuc Vien, Vice President of Viet-German University, assessed that the conference is an opportunity to connect and develop a global academic network, opening up opportunities for scientists to cooperate in teaching and research. He wants scientists to evaluate and propose technological solutions that use resources effectively, solve the challenges people face and aim to develop green industry.
Quality works at GCSM 2024 will be selected and published in the book series “Lecture Notes in Mechanical Engineering” published by Springer Publishing House.
