挑战
德纳公司是汽车行业零部件和总成的领先供应商,在设计重型卡车悬架系统和其他总成时面临着重大挑战。由于这些部件的负载重、环境恶劣且寿命要求长,这项任务十分艰巨。从历史上看,这些组件被过度设计且更重,以满足可靠性要求。然而,在当前经济形势下,商用卡车的重量及其对车辆成本、乘坐和燃油经济性的影响成为卡车制造商和最终用户的重要关注点。面临的挑战是用最少的材料设计这些零件,但仍保持足够的强度和刚度。必须在满足紧张的预算和产品发布时间表的同时实现这一目标,从而排除了构建和测试大量硬件原型的可能性。

解决方案
作为产品设计过程的一部分,Dana Corporation 的商用车工程师使用 ANSYS Mechanical 软件的拓扑优化功能来优化组件重量。该方法首先通过多体仿真确定载荷。然后构建初始粗糙实体模型以填充组件允许的最大可用空间包络。接下来,开发了有限元网格,ANSYS 拓扑优化例程自动消除了刚度低于指定阈值的单元。结果是一个分析模型,仅包含用最少的材料维持组件所需刚度所需的元素。然后将该拓扑优化模型叠加在实体模型上,以指导工程师完成重量优化零件的详细设计。

Transformation for IoT Business Model in Connected Industrial Vehicles
CNH Industrial wanted to put IoT-enabled viechles onto the market. Whether monitoring a single machine or integrating an entire fleet, operators are able to track the status, speed, and movement of machines and their performance and also receive alerts on issues that may require service by a qualified technician to improve uptime and overall effectiveness of the vehicle.
Case Study
Integral Plant Maintenance
Mercedes-Benz and his partner GAZ chose Siemens to be its maintenance partner at a new engine plant in Yaroslavl, Russia. The new plant offers a capacity to manufacture diesel engines for the Russian market, for locally produced Sprinter Classic. In addition to engines for the local market, the Yaroslavl plant will also produce spare parts. Mercedes-Benz Russia and his partner needed a service partner in order to ensure the operation of these lines in a maintenance partnership arrangement. The challenges included coordinating the entire maintenance management operation, in particular inspections, corrective and predictive maintenance activities, and the optimizing spare parts management. Siemens developed a customized maintenance solution that includes all electronic and mechanical maintenance activities (Integral Plant Maintenance).
