低成本设计: 仿真工程的意义

仿真工程(SBE)工具— 例如有限元分析、计算流体动力学和电磁场求解器 — 已经得到验证,能为国防工业的产品研发过程增加价值。事实上,大量报告显示这类工具在该行业中实现了显著的投资回报。然而,业内往往将重点放在工具的功能上。基本功能固然重要,但是,即便是业界一流的研发机构,要想充分发挥这些工具的价值,仅仅学会基本功能是远远不够的。一般来说,如何使用工具(过程),谁来使用工具(人),这些因素并没有得到广大建模和仿真社群的足够重视,甚至被完全忽略。这就会导致产生低效率因素,成为当前业务和新项目方案的内在成本。

在国防开支紧缩和不确定性增加以及低成本设计(DfA)主导的时代背景下,研发机构必须解决这些低效率因素,才能在不增加成本的前提下做更多事情。

通过对国防建模与仿真领域进行调研,了解全球很多主要的政府机构和承包商如何利用仿真设计,ANSYS已经找出了造成内部效率低下的三个主要原因:

  • 不同工程学科和职能相互分离,造成相互间的数据交换过程存在缺陷
  • 数据和知识重用受到限制
  • 缺乏对员工培养、培训和任务自动化的重视

本白皮书将探讨仿真工程与低成本设计的关联性并介绍内部效率低下的起因。文中介绍了业界一流的研发机构为解决低效率问题所采用的一些最佳实践。

工程知识管理

近年来,商业发展推动了人们对托管仿真环境的需求,同时还促进了一些被广泛认可的企业计划(如全面质量管理(TQM)和六西格玛)。“减少生产周期”和“提高质量”等工程要求已经转化为一些商业目标,如“降低成本”和“提高盈亏底线”。这些商业需求催生了“虚拟原型”或“仿真驱动的产品研发”等概念。

对很多人而言,产品生命周期管理(PLM)已成为解决这一严峻挑战的软件启用型解决方案代表。从广义上来说,PLM是一种信息驱动的方法,可用于管理产品生命周期的各个方面。产品的“生命周期”涵盖其设计、生产、部署、维修以及最后的停止服务与处理。通过协调并整合产品生命周期内用到的各种过程、方法、工具和数据,PLM可以简化上述步骤。虽然这种方法备受关注,但是它依旧存在很多缺点,尤其是应用于计算机辅助工程(CAE)时。

PLM是文件管理系统或产品数据管理(PDM)系统的副产物,这些系统最初开发用于管理计算机辅助设计(CAD)数据。因此,PLM系统依然主要以文件为中心,并不十分适合管理与CAE仿真相关的过程和数据。实际上,通常将CAE的使用限制在产品生命周期中一个很小但又极其重要的领域,具体而言就是产品工程领域。由于管理仿真过程及数据实际是更大PLM愿景的一个专门的子模块,因此当今的PLM解决方案通常会忽视或者没有妥善地处理该问题。

本文的目的在于描述相关方法,通过解决与卓有成效的CAE整合使用相关的关键产品工程问题,实现“托管仿真环境”或“仿真驱动的产品研发”。

ANSYS HPC Gateway Part of the ANSYS Engineering Knowledge Manager Solution - White Paper

While engineering simulation has been a best practice in product development for more than 40 years, today’s simulations are much larger, more complex and more computationally intense than ever. As engineers study products at the system level, apply multiple physics and add smart functionality to existing designs, product models have grown exponentially in their numeric scale.

Fast-Tracking Advanced Driver Assistance Systems (ADAS) and Autonomous Vehicles Development with Simulation

ADAS and autonomous vehicles will soon be transforming our world. Due to the complexity of this immense engineering challenge, manufacturers now realize producing a reliable autonomous vehicle requires millions of miles of road testing—as onboard computers must be trained, not programmed. A seemingly impossible task.

These same companies also recognize simulation as the only method to test and iterate millions of possible scenarios. Perhaps most impressively, simulation modeling provides greater precision, faster results and significant cost savings.

  • Ways of leveraging simulation in autonomous vehicles and ADAS development
  • Simulation examples, benefits and tools
  • A roadmap for simulation implementation

The Race to 6G — Faster Networks and Devices Promise a World of New Possibilities - White Paper

The impact of electronics is being felt in every industry. One key enabler is the continuing evolution of the integrated circuit (IC) toward higher speeds and lower power consumption, providing the ability to make products of all kinds smaller and more powerful. Increasing frequencies and shrinking geometries create a range of new challenges for engineers and designers: signal integrity, electromagnetic interference, thermal performance and mechanical integrity ―problems that cross physics disciplines and must be studied at both component and system levels. Multiphysics simulation is usually thought of as an engineering tool, but it has business implications as well, especially applicable to today’s highly competitive marketplace.

Engineering Knowledge Management - White Paper

The business forces driving the need for a managed simulation environment have been with us for years and have been the impetus for the widely recognized corporate initiatives such as Total Quality Management (TQM) and Six Sigma. Engineering mantras such as reduce cycle time and improve quality translate into business objectives such as reduce costs and improve the bottom line. These needs have given rise to the concept of Virtual Prototyping or Simulation Driven Product Development.
