挑战
Scania CV AB 是一家领先的卡车和客车制造商,在准确模拟卡车驾驶室内的吱吱声和嘎嘎声方面面临着挑战。吱吱声和嘎嘎声是当组件的两个部件由于特定的激励负载而相对运动时观察到的两种现象。在汽车行业,研究这些现象是为了降低车内噪音并提高乘员的乘坐质量和舒适度。历史上,斯堪尼亚的客舱开发部门并未进行过此类模拟。该团队必须依靠公差计算和材料选择来降低吱吱声和嘎嘎声的风险。当第一个原型可用时,进行了迭代来修复和纠正最终设计以解决噪声问题。为了缩短开发时间并减少迭代变更,需要一种能够在客舱开发周期的早期阶段实现仿真驱动设计流程的解决方案。
关于客户
Scania CV AB 是世界领先的重型运输卡车和客车以及工业和船用发动机制造商之一。公司业务中越来越多的部分涉及金融和服务领域的产品和服务,确保斯堪尼亚客户拥有经济高效的运输解决方案和最长的正常运行时间。斯堪尼亚拥有 32,800 名员工,业务遍及约 100 个国家。研发活动集中在瑞典,而生产则在欧洲和南美洲进行,并拥有零部件和整车的全球互换设施。 2012年,发票销售额总计796亿瑞典克朗,净利润达83亿瑞典克朗。
解决方案
斯堪尼亚与 LeanNova Engineering AB 和 Altair ProductDesign 合作,协助斯堪尼亚卡车驾驶室的开发过程。该解决方案涉及使用 Altair 的吱吱声和嘎嘎声总监 (SNRD) 来模拟吱吱声和嘎嘎声现象。可以在设计过程的早期进行仿真,从而提高首次设计的正确性并减少物理测试的需求。仿真还可以显着减少时间,使工程师能够利用有限的资源及时执行更多分析。在 16 个月的时间里,斯堪尼亚现场进行了两次完整的设计循环和多项设计研究。第一步涉及现有驾驶舱塑料部件的模态关联,以改进未来模拟的材料数据库。第二步是建立各种类型座舱的整车模型,并通过施加道路测试测量的载荷,计算定义界面处的相对位移。

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).
