汽车电子

据估计,下一代汽车几乎一半的成本会用在随车携带的电子产品和机电元件上。制造商在先进引擎、安全控制、电动/混合动力驱动器和导航、音响系统以及指示灯设计等方面正使用先进的电子产品。因此,汽车电子设计工程师面临着各种挑战。

工程师设计的产品必须能够生存在恶劣的工作条件下,如在湿度水平显著波动下,以及温度从50摄氏度到-20摄氏度大范围的显著波动下。此外,产品必须表现出相对较长的生命周期。汽车行业是受高安全性和可靠性标准控制的。最后,由于减少燃料消耗的要求,汽车的重量也受到严格的限制。

ANSYS产品系列是用于汽车电子和机电设计的理想选择


通过虚拟仿真,最好的产品工程工具减少了对物理样机的依赖。ANSYS系列组件远远超越同行,便利了不同工程学科之间的交叉融合沟通。对于汽车行业,这是缩短设计周期和降低产品召回风险的重要因素。

ANSYS产品建立在足够的广度和深度基础上,使个人和团队能够进行全面的多物理场和多尺度仿真。优化产品在恶劣操作环境下的性能和可靠性是产品设计的最终结果,从而满足了该行业最严格的限制。

ANSYS为汽车电子设计人员提供了多种多样的工程仿真工具,解决了多物理场所固有的各种部件和系统的设计难题。
