Since 20 16, BYD and BASF, a material supplier, have been cooperating in various automotive applications. Lijun Wang, senior engineer of BYD Chassis, said: "BASF's advanced lightweight materials contribute to the sustainable development of the electric vehicle industry. The newly launched electric vehicle motor mounting bracket is more than 40% lighter than the same aluminum bracket, which will help electric vehicle customers improve their cruising range. "
This brand-new motor mounting bracket for electric vehicles is injection molded with glass fiber reinforced polyamide ULRAM ID A3WG 10, which has high mechanical bearing capacity and is not easy to creep in the engine room even under continuous load.
In addition, according to the installation conditions in the engine room, the bracket can bear higher bending moment. This new mounting bracket also improves the shock absorption performance of the vehicle, and can provide heat insulation protection for the rubber parts in the bracket, thus prolonging the service life.
In addition to testing the performance in the bench test, BASF also cooperated with Anhui Zhong Ding Shock Absorbing Rubber Technology Co., Ltd., a plastic bracket manufacturer, and used BASF's proprietary computer-aided simulation technology Ultrasim? , accurately predict the performance of parts under various loads and environmental conditions.
So, Ultrasim? In the early stage of development, this technology is helpful to optimize the design scheme, improve the strength and performance of components and improve the utilization rate of materials. This also greatly reduces the number of initial samples for installing the bracket, and the bearing capacity of the bracket can be improved by adjusting the arrangement of reinforcing ribs at the initial stage of development.
