(from:NET)
LMS Virtual.Lab提供一套集成软件平台用以模拟机械系统的品质属性,如结构完整性、振动噪声、耐久性、系统动力学特性、驾驶的平顺性及操纵的稳定性等。LMS Virtual.Lab包括所有关键过程步骤及所需的技术,可对每个关键属性进行从头到尾的评价。使用LMS Virtual.Lab,工程团队可以建立精确的仿真模型,模拟其真实的性能,并能在实物样机建造之前快速有效地评估及优化设计方案。

精确仿真产品的真实工作特性

日益激烈的市场竞争促使制造商不断提供具有足够吸引力的产品,以满足或超越客户的期望。这就需要可靠的设计流程和界面友好易用的工具,帮助他们对新产品功能品质属性设计进行深入地了解,LMS Virtual.Lab恰恰满足这一要求。它能够精确地建立模型,并能仿真在真实的工况下产品的机械设计特性。LMS Virtual.Lab强大而精确的求解器,创新的工具,全面考虑进了使用者的真实使用情况,可准确地检测出产品设计的薄弱环节,使用户能够及时有效地评估多种设计方案,从而做出设计决策。

产品开发流程化

为了缩短产品推向市场的时间,研发部门必须加快研发过程的每个环节。LMS Virtual.Lab使他们可以从产品概念设计的早期,在建立详细的CAD模型出来之前就对产品设计进行评估。产品研发团队能够从一开始就做出正确的决策,从多个学科平衡产品的性能。更重要的是,可以避免以后昂贵的设计修改。LMS Virtual.Lab能有效捕捉和自动完成仿真过程,进而快速评估多种设计方案。其高效的求解器能以空前的速度和准确性处理大型仿真模型。总之,在不断缩短的产品开发周期的情况下,LMS Virtual.Lab是设计和开发更好产品的理想工具。


LMS国际公司已发布了它最新版本的仿真功能集成解决方案:LMS Virtual.Lab Revision 10。该软件包含了许多新的特征,从多体动力学仿真到有限元声学模拟, 会将客户的仿真能力提升到一个全新水平。

“随着版本10的发布,我们以加快计算速度和提高生产效率作为重点。我们的声学仿真软件用户会显著地提高计算速度,这源于尖端技术如AML方法(自动匹配层方法)和新的MUMPS求解器的使用;同时我们的多体动力学仿真用户也能中得到益处,例如,新的求解管理器可以管理多个项目。”LMS国际公司仿真部的副总裁Stefaan Goossens说。

在声学仿真方面,有限元声学以各种定制求解器为重点,以保证计算速度和提高处理效率为特征。客户最关心的也许是AML方法(自动匹配层方法), 这一被称为”下一代的PML”(完全匹配层方法)不需要模拟PML吸收层。求解器在靠近辐射系统处自动提供一个简化的有限元网格,并保持小尺寸单元,便于网格的管理和快速求解。

除了AML方法,还有其他新的特征能加速计算,包括MUMPS求解器(多波前大规模并行稀疏直接求解器),和VATV技术(声振传递向量),这是LMS国际公司的专利技术。这个新的版本还可以考虑温度对声音的影响。

LMS Virtual.Lab Motion这个流行的多体动力学仿真软件包(MBS)也提高了生产效率。新的求解管理器可以让该软件处理大量的分析案例,它还可以自动地进行数据管理。新添的LMS Virtual.Lab Motion-ABAQUS接口程序可以实现与非线性有限元的耦合仿真。该耦合仿真结合了特定部件的非线性计算精度和多体动力学的计算速度。对多体动力学求解器技术的连续投资明显改进了求解器在求解实际模型时计算速度。

LMS Virtual.Lab Durability Thermal Fatigue软件包提供了一个计算高温循环和蠕变疲劳的准确、快速求解器。另外进一步改善了焊缝的模拟精度,还可以快速计算疲劳寿命。

LMS Virtual.Lab Structures软件包是一个结构模拟和分析的集成方案,它包括对ABQUS软件的统一装配模拟支持,而且具有从CAD到CAE结果的先进的完全自动处理能力,用户可以从中节省50%的时间。

LMS Virtual.Lab offers an integrated software suite to simulate and optimize the performance of mechanical systems for structural integrity, noise and vibration, system dynamics and durability. LMS Virtual.Lab covers all the process steps and required technologies to perform an end-to-end design assessment in each key discipline. Using LMS Virtual.Lab, engineering teams can build accurate simulation models, simulate their real-life performance, quickly assess multiple design alternatives and optimize designs before prototype construction.

LMS Virtual.Lab Acoustics
FEM acoustics offers a variety of custom-fit solvers and features for guaranteed speed and process efficiency. Them main new item is AML (Automatically Matched Layer). Called the “next generation PML” (Perfectly Matched Layer), AML eliminates the need to model the absorbing PML layer. The solver does it automatically, delivering a simplified FEM mesh close to the radiating system. The FEM elements are purposely kept small so that the meshes are manageable and quickly solved.
Besides AML, other speedy new acoustic features include a MUMPS Solver (Multi-Frontal Massively Parallel Sparse Direct Solver) and VATV (Vibro-Acoustic Transfer Vector), an LMS Patented methodology. New to this release as well is temperature mapping, taking in the effect of temperature on acoustics.

AML (Automatically Matched Layer)
Because the FEM mesh around the system is built very close to the radiating system, the amount of FEM elements can be kept very small, therefore these meshes are very efficient to handle and ultimately solve.

MUMPS (Multifrontal Massively Parallel Sparse Direct Solver) Solver
Significantly faster solution compared to current FEM solvers

Temperature Mapping
For some acoustics applications, the temperature can be an important, critical item. For example, in the case of exhaust systems, temperature can be high and therefore it will influence significantly the acoustics.

VATV (Vibro-Acoustic Transfer Vector)
When dealing with “random” applications such as Turbulent Boundary Layer excitation of an aircraft fuselage or when dealing with wind loads on a window, traditional techniques will take significant time. The new VATV technique (building on our experience of ATV), extends the ATV technique to coupled problems and will as such handle these problems very efficiently.

Duct Modes
Method to gain significant more insight into how noise is propagating inside ducts. With this insight, understanding the countermeasures can be more efficiently designed for

LMS Virtual.Lab Motion

The new Solutions Manager makes it possible to handle large sets of analysis cases, many with automated data management. New as well is the LMS Virtual.Lab Motion-ABAQUS connection for non-linear FE co-simulation. This co-simulation combines the accurate non-linear representation of certain components with the calculation speed of MBS. The continued investment in MBS Solver technology brings yet another significant solver speed improvement in solving realistic models in accelerated timing.

Co-simulation with Abaqus
The 2 solvers (Motion and Abaqus) work in co-simulation. Simulate certain system components with a nonlinear FE package like Abaqus, while the rest of the system is simulated with multi-body technology.

Solutions Manager
Save time in running and managing different cases: simulate as fast as possible different design variants with different parameters, different loading conditions and different boundary conditions.

Motion-TWR
This unique feature allows to simulate an unconstrained vehicle, to correlate multi-body models with test data, to transfer spindle loads from an old vehicle to a new vehicle and to serve as help for testing on physical durability test rigs.

LMS Virtual.Lab Durability

Accurate and fast, LMS Virtual.Lab Durability Thermal Fatigue, provides a unique solution for high temperature cyclic and creep fatigue. Further improvements to Seam Weld modeling enable accurate and fast fatigue life calculations.

High Temperature Fatigue
Possibility to perform simulation of thermal shocks with only simple test data needed

Seam Welds: Stress Approach
Use automated stress based methods for fatigue of seam welds.

LMS Virtual.Lab Noise and Vibration

Structural damping modeling
The structural damping is a key component in reducing noise levels. Very efficiently study the effect of damping on the noise levels.

LMS Virtual.Lab Structures

LMS Virtual.Lab Structures, the integrated solution for structural modeling and analysis, includes unified assembly modeling support for ABAQUS, and further advancing the ability to fully automate the process from CAD to CAE Results, with customer documented gains of 50% or more in time it takes to create and post-process a model.

Unified assembly modeling supported for ABAQUS
Being able to leverage the unified assembly model directly for Abaqus

ANSA
Alignment to ANSA Rev 13 & Semi-automatic mesh correction with ANSA from Virtual.Lab

    小贴士:
  1. 类似“顶”、“沙发”之类没有营养的文字,对勤劳贡献的楼主来说是令人沮丧的反馈信息。
  2. 提问之前请再仔细看一遍楼主的说明,或许是您遗漏了。
  3. 勿催片。请相信驴友们对分享是富有激情的,如果确有更新版本,您一定能搜索到。
  4. 请勿到处挖坑绊人、招贴广告。既占空间让人厌烦,又没人会搭理,于人于己都无利。
  5. 如果您发现自己的评论不见了,请参考以上4条。
