ESI发布Virtual Performance Solution 2011新版本

针对多领域的端对端虚拟原型解决方案的可升级软件包

法国巴黎,2011年10月4日---世界领先的工业虚拟原型及制造解决方案供应商ESI-GROUP宣布发布最新Virtual Performance Solution (VPS) Version 2011。Virtual Performance Solution (VPS) Version 2011.可以帮助客户控制设计迭代，缩短产品研发周期降低研发成本同时保证高的产品质量标准。

ESI已开发最新的VIRTUAL PERFORMANCE SOLUTION2011来适应当今主要工业所面临的各种挑战；如何应对新的交通安全与环境保护法规，同时降低重量？如何评估新材料和制造工艺对产品性能带来的的影响？如何平衡日益复杂的产品各种性能要求之间的矛盾并开创革命性的变化，同时大幅降低研发的成本和时间？

Virtual Performance Solution 2011为广大工业用户提供了一个横跨多个分析领域的数值模拟解决方案，可以处理一系列的模拟仿真问题，包括: 碰撞，冲击和乘员安全；乘员舒适性；非线性静力学及动力学；热力学；NVH以及最新的内饰声学。

新加强的玻璃模型能方便用户更加准确的模拟EURO-NCAP汽车安全条例所规范的头部与车辆挡风玻璃之间的碰撞过程，这一全新模型已经被大众集团快速采纳应用并取得令人满意的效果。

大众集团项目经理Helge Liebertz博士表示：在大众集团，我们已经应用Virtual Performance Solution进行各种分析已经有很多年了，在与ESI的合作下，由于我们采用最新Virtual Performance Solution2011中专门为安全玻璃所开发的非局部失效模型准则，使头部与挡风玻璃碰撞模拟变得更加准确。我们可以利用许多试验与仿真结果对比来衡量一个准则，我们可以断言最新的Virtual Performance Solution玻璃模型在处理工业领域面临的多种载荷工况时这种模型是非常卓越的。

VPS2011提供给用户一个独特的多物理场处理能力即基于一个统一核心模型来进行多领域的协同仿真及优化；使得跨领域跨设计之间的协同与同步工程成为可能，且考虑到耦合因素能为用户大幅降低不同分析领域间模型传递的时间和工作量，最终使用户不必为许多不同求解器及其单一的仿真过程而困扰进而明显降低仿真流程的复杂程度，由此使得产品的快速设计更新成为可能。VPS同时允许用户通过对接触、非线性特征以及制造工艺过程适当考虑来改善仿真质量来达到优化设计安全裕度的目的。

VPS2011为NVH工程师专门开发的最新模块中包含一项最新的内饰声学模块，能帮助工程师准确预测结构加载下的中低频频率响应。

最新版本的VPS同时也集成了ESI产品舒适性解决方案PAM-COMFORT，ESI这一虚拟座椅原型解决方案能对座椅设计的裁片装套等过程进行模拟仿真，能精确预估座椅在大量设计变化及不同载荷工况下的产品物理性能表现。

所有仿真工具都基于一个求解器包Virtual Performance Solution和一个通用的用户环境VISUAL-ENVIRONMENT下。

“新发布的Virtual Performance Solution涵盖了许多新的特征，不仅仅可以用来帮助用户改善车辆耐撞性和乘员安全性，同时也能改善乘员在车内的总体感受。例如，现在降低车内噪声同时减小结构振动是可行的---这两个参数是用户体验汽车产品质量影响最直接的因素。由于跨领域的虚拟原型协同仿真成为可能，新的2011版VPS可以帮助客户简化产品研发流程提高工作效率，加速项目研发同时降低成本来应对日益剧烈的市场竞争。”VPS产品经理Peter Ullrich

ESI offers a wide range of simulation applications for Virtual Performance including crash, impact and occupant safety, linear & nonlinear statics & dynamics, strength & thermal, NVH (noise, vibration and harshness) as well as interior acoustics and seat prototyping. All these applications for Virtual Performance are grouped together in one coherent software solution package: Virtual Performance Solution (VPS).

Paris, France – 4 October, 2011 – ESI Group, pioneer and world-leading solution provider in virtual prototyping for manufacturing industries, announces the release of Virtual Performance Solution (VPS) Version 2011. Virtual Performance Solution enables ESI’s customers to shorten product development time by mastering design iterations and reducing costs while ensuring high quality standards.

The latest version of Virtual Performance Solution was developed to address today’s main industrial challenges. How to cope with new safety and environmental regulations for transportation, while reducing weight? How to anticipate the impact of new materials and manufacturing processes on product performance? How to reconcile conflicting requirements and bring revolutionary changes to increasingly complex products, while cutting development costs and time drastically?

Virtual Performance Solution 2011 provides numerical simulation across multiple domains: crash, impact & occupant safety; passenger comfort; linear and nonlinear statics & dynamics; strength and thermal performance; noise, vibration & harshness (NVH); and, most recently, interior acoustics.

New enhancements include a glass model to simulate head impacts on a vehicle’s windscreen; required by part of the Euro NCAP car safety performance assessment program.

VPS 2011 offers unique multi-physics capabilities for multi-domain optimization with a single core model. It enables collaborative and simultaneous engineering work across domains and components, taking into account coupling effects, while saving model translation tasks between domains. Not having to deal with multiple solvers and individual processes for each product part leads to a significant reduction in the workflow’s complexity and hence enables faster design changes. VPS also allows customers to optimize safety margins, by improving simulation quality thanks to proper consideration of contacts, nonlinearities, and manufacturing history. Furthermore, VPS helps reduce IT costs by using one single scalable solution with fewer software installations.
