On June 22, 2020, China's leading new energy vehicle manufacturer BYD Automobile Co., Ltd. (referred to as: BYD) launched a new electric vehicle motor mounting bracket on its first global new energy vehicle sharing platform "e platform". Compared with traditional aluminum brackets, this motor mounting bracket uses BASF's high-performance material Ultramid® polyamide, which can effectively improve shock absorption and thermal insulation performance, and it is lighter at the same load capacity level.
Wang Lijun, a senior engineer of BYD chassis, said: "We and BASF have started good cooperation on various automotive applications since 2016. With BYD's first global electric vehicle sharing platform on the line, we will be able to use BASF's advanced lightweight materials to promote products To the market, to help the sustainable development of the electric vehicle industry. The newly launched electric vehicle motor mounting bracket uses BASF Ultramid® material, which is more than 40% lighter than the same aluminum bracket. This feature will help electric vehicle customers improve. recharge mileage."
This new electric vehicle motor mounting bracket is injection molded from glass fiber reinforced polyamide Ultramid® A3WG10. It has a high mechanical load-bearing capacity and is not prone to creep in the cabin even under continuous load. In addition, the bracket can withstand high bending moments according to the installation conditions in the cabin.
Thanks to its excellent shock absorption performance, the new mounting bracket can bring passengers a more comfortable driving experience. In addition, the thermal conductivity of BASF Ultramid® polyamide material is greatly reduced compared to aluminum, which can provide the best thermal insulation protection for the rubber parts in the bracket, thereby extending its service life.
Desmond Long, Global Vice President of BASF's Asia Pacific Specialty Materials Transportation Division, said: "The electric vehicle industry is always looking for lightweight, composite materials that improve NVH performance. BASF can help by providing sustainable and innovative solutions The electric vehicle industry achieves these goals."
In addition to testing performance in bench tests, BASF also cooperated with Anhui Zhongding Shock Absorber Rubber Technology Co., Ltd., a leading manufacturer of plastic brackets, in the initial development of this complex mounting bracket. The computer-aided simulation technology Ultrasim® accurately predicts the performance of parts under various loads and environmental conditions. Therefore, Ultrasim® technology helps optimize the design scheme in the early stages of development, maximize the strength and performance of components, and improve material utilization. This also greatly reduces the number of initial samples of the mounting bracket, and can improve the load-bearing performance of the bracket by adjusting the reinforcement rib arrangement and other measures in the early stage of development.
Andy Postlethwaite, Senior Vice President, Asia Pacific, BASF Performance Materials, said: "We always focus on close cooperation with customers, and strive to meet customers' market needs and regulatory requirements. BASF's new business and incubation business department will also further Improve market insight, create more opportunities for cooperation with customers, and help us quickly improve our ability to innovate and enter new markets."
With strong R&D and simulation capabilities, BASF can help partners optimize and jointly develop innovative applications, while reducing development costs and achieving faster commercialization. In 2019, BASF has completed more than 40 innovative applications in many industries through innovative material solutions and R&D capabilities.
