虚拟测试，现实生活的好处
农业设备必须在一系列环境中安全有效地运行，这使得测试变得复杂，昂贵且具有挑战性。 通过引入虚拟测试，凯斯纽荷兰工业集团正在简化整个过程
农业设备的试驾必须在最严格的安全条件下进行，并在可控的情况下进行。 操纵一台25吨的联合收割机穿过不平坦的田地可能是一件棘手的事情，因此必须做出最大的预防和考虑。 CNH Industrial’s development of virtual testing is transforming that risk profile, as well as reducing the time, costs, and carbon emissions involved.
变化之风
农业部门正在迅速发展。 计算机能力呈指数级增长，从土壤到作物再到天气状况，所有方面的数据量都有了巨大的增长。 产品测试也在不断发展，这有助于农业技术取得重大飞跃。
凯斯纽荷兰工业集团正在利用高性能计算机（HPC）仿真和计算机辅助工程（CAE）加速和改进产品开发和制造过程。
自主之路
目前，大多数现代农用车辆通过交互式用户界面和先进的传感技术增强了操作员的作用，使车辆能够自我定位并避免危险。 然而，下一步已经在我们面前：监督自主，即操作员监督无人驾驶车辆。 最终，凯斯纽荷兰工业集团将提供完全自主，农业机械将能够在完全远程监督下执行各种任务。
在现实环境中测试这些车辆既昂贵又耗时，而且需要严格的安全协议。 通过在虚拟环境中进行测试，凯斯纽荷兰工业集团加快了完全自主的设计过程，同时最大限度地减少了职业安全问题。

一种更安全的测试方法
凯斯纽荷兰工业集团在整个产品开发过程中高度重视安全性。 从驾驶员的健康到车辆在不平坦地面上的稳定性，一切都必须考虑在内，并减轻IM体育的危险。
Normally, the product development team would run a series of “bump tests” for farming equipment, which monitors vibrations, analyzes the forces on specific elements of a design, and checks the pressures on hydraulic components. But now, by combining a variety of modeling techniques with physical components, CNH Industrial has created a simulation environment that mirrors standard testing, creating a “digital twin.” 通过转换到虚拟设置，设计验证变得更加安全。
虚拟测试
虚拟测试特别有效的一个领域是驾驶室设计，在这个领域，驾驶员的舒适度和安全性将被评估。 通过使用虚拟驾驶室，车队可以密切监控驾驶员舒适度和控制的可及性等因素。 Whereas traditionally, a person would have had to physically sit in the cab for ergonomic testing – possibly in some potential discomfort – the virtual system can assess all the design factors.
虚拟测试还允许客户在设计过程中提供输入和反馈。 使用虚拟驾驶室，他们可以查看解决方案，跟踪设计开发，并亲眼看到产品设计的改进。

削减成本和时间
传统的测试要求农业设备在广泛的环境和作物中进行评估。 Gennaro Monacelli, CNH Industrial’s Global Director of Design Analysis and Simulation, explains the process in more detail: “If we need to field test a tractor or a combine, we might have to ship a prototype to a remote country and synchronize the development time with the harvest season, in order to test the different missions of our agricultural machinery.
Any delays in product development mean the prototype may not be ready, thus missing a whole season of testing and resulting in almost a year’s delay. We can mitigate this risk using virtual simulation and simulating tire-soil interaction, anticipating many tests digitally.”
By running a virtual test, evaluations are effectively immediate, but it is also possible to learn more about the machine’s operation than during standard physical testing.
“When we harvest crop such as sugarcane in real life,” says Monacelli, “we aren't able to see what is happening inside the machine. But through virtual testing, like computational fluid dynamics and crop modeling, we can do exactly that.”
通过这些模拟，我们可以分析机器内部所有系统的动力学。 The Company’s ability to monitor the exact crop flow at every point inside a virtual machine, makes testing more accurate and allows for further enhancements.

虚拟测试减少了碳排放和风险
以传统的方式测试车辆会产生大量的碳排放。 农业设备将需要相当多的时间和公顷才能达到必要的信心水平。 运行虚拟模拟大大减少了这些排放。
Monacelli指出，原型车的碳足迹很高。 “When building a prototype, you know it is ultimately destined for the landfill,” he says. “It’s a significant investment and thanks to virtual testing, we don’t always need to develop one, as simulations become more realistic and predictive.”
To produce an autonomous vehicle, myriad elements – including cameras and LiDAR (Light Detection and Ranging, a remote sensing method that uses pulsed laser light to measure ranges) – must all be tested. 虚拟测试可以用于设计过程的每个元素，从评估拖拉机的一个小部件到最终产品的功能。
“On larger farms, vehicles will soon be able to communicate with each other. In the future, we will be able to tell farmers the optimum time to harvest a crop, and the combine will harvest with fully remote supervision,” says Monacelli.
凯斯纽荷兰工业集团继续投资于尖端技术的开发和实施，从而提高客户满意度和安全性。 The use of virtual testing will not only reduce risks but will ultimately provide the customer with an optimal – and comprehensively vetted – product.
