					<description><![CDATA[噪声、振动与声振粗糙度（Noise、Vibration、Harshness）的英文缩写。这是衡量汽车制造质量的一个综合性问题， 它给汽车用户的感受是最直接和最表面的。车辆的NVH问题是国际汽车业各大整车制造企业和零部件企业关注的问题之 一。有统计资料显示，整车约有1/3的故障问题是和车辆的NVH问题有关系，而各大公司有近20%的研发费用消耗在解决 车辆的NVH问题上。NVH问题是系统性的。例如有些轿车行驶时车厢噪声大，查源头在发动机，那么这一个噪声问题可能 就涉及到三个部分，一个是发动本身的噪声大，一个是发动机悬置部件减振效果差，一个是车厢前围和地板隔音技术不 好，是一个互相关连的系统问题。 振动及噪音的运用Case 汽车NVH性能分析 NVH特性的研究不仅仅适用于整个汽车新产品的开发过程，而且适用于改进现有车型乘坐舒适性的研究。这是一 项针对汽车的某一个系统或总成进行建模分析，找出对乘坐舒适性影响最大的因素，通过改善激励源振动状况(降 幅或移频)或控制激励源振动噪声向车室内的传递来提高乘坐舒适性 制动器刹车噪音模拟分析 对一车型轿车盘式制动器的噪声产生机理进行研究，利用有限元分析软件进行制动噪声的分析。发现在摩擦系数分别为0.3和0.5时都在2.0kHz这个频率产生了不稳定的状态，可见摩擦副特性并不是制动噪声产生的决定性因素。通过对结果的分析，对制动系统提出了改进方案。 累计仿真分析座椅系统项目 100+ 累计仿真分析天窗系统项目 200+ 累计仿真分析电动尾门系统项目 100+ 累计仿真分析玻璃升降机系统项目 200+ Get Started Business Right Now!

					<description><![CDATA[目前，流体力学的研究和分析手段分为理论分析、实验研究及数值计算三种。理论分析的方法是在研究流体运动规律 的基础上，建立各种简化的流动模型，形成描述流动的各类型控制方程；在一定假设和条件下，经过解析推导及运算， 得到问题的解析解或简单解。 长期以来，实验研究一直是流体动力学的主要研究手段， 其原理是利用相对运动原理，建立地面实验设备，如水洞、水槽、风洞、激波管等获得相关数据。但是，实验研究一般 是在模拟条件下完成的，几乎所有的地面实验设备都不能完全满足所有相似参数、相似定律要求，而且实验除了存在洞 壁效应、支架干扰、测量误差等外，还存在高超声速流动中真实气体的非平衡效应等很难模拟的因素，所以实验研究也 受到不少限制。一般来说，实验研究周期长、费用高。 计算流体动力学(Computational Fluid Dynamics)，简称CFD。它是利用计算机和数值方法求解满足定解的流体动力学方程,以获得流动规律和解决流动问 题的专门学问。计算流体动力学作为一门专门学科，大约是20世纪60年代形成的。现在CFD已深入到与流动有关的技术领 域。  汽车行业的运用Case 进排气岐管分析 对于汽车排气系统而言，通常由两部分组成：热端与冷端。其中热端主要由涡轮增压器、歧管以及三元催化 器等组成；冷端主要由消音器、排气管以及一些吊钩、支撑悬挂等组成。热端部分紧连着发动机，其温度通常 都能达到850。C左右，温度对于材料的力学性能会产生很大影响，因此温度对于汽车排气管热端的振动耐久性 能的影响不可忽略。 飞机气流分析 由于CFD在节省研制费用、缩短研制周期、实现研制数字化自动化、提高研制质量等方面的优势，越来越多的 人认为未来飞行器性能的确定，将依赖于在“虚拟风洞”（CFD）数据基础上产生的“虚拟飞行”，这将是飞行器研制 的主要发展方向。以数值求解Euler方程和RANS方程为代表的CFD技术已经广泛应用;改变了传统的空气动力学研究 和设计方法，推动了这些领域的技术进步。 汽车风道气流分析 根据空调系统的试验结果仅能够得到出风口风速、风量、压降等有限的数据，这对于整个系统的改进是远远不 够的。利用CFD软件进行计算，可以得到风道内任意一点的详细流场情况，风道内部的涡流情况也可以很容易看出。 同样，进行外流场计算时，可以得到车身周围详细的流场情况。 累计仿真分析座椅系统项目 100+ 累计仿真分析天窗系统项目 200+ 累计仿真分析电动尾门系统项目 100+ 累计仿真分析玻璃升降机系统项目 200+ Get Started Business Right Now!

					<description><![CDATA[在工程实践中，有限元分析软件与CAD系统的集成应用使设计水平发生了质的飞跃，主要表现在以下几个方面：增加设计功能，减少设计成本；缩短设计和分析的循环周期；增加产品和工程的可靠性；采用优化设计，降低材料的消耗或成本；在产品制造或工程施工前预先发现潜在的问题；模拟各种试验方案，减少试验时间和经费。 通用分析仿真的运用Case 机构仿真 整体式链轮作为扶梯驱动部件中非常重要的部件，对扶梯安全性，耐久性影响紧密。运用多体动力学的非线性分 析，及静力学的计算方式分析，在机构运转过程中，基于结构对称，链轮每转过60°，出现一次相同的受力状况，链轮由位置1转动 60°到达位置2，我们取这两种典型位置对链轮进行静态受力分析。 强度分析 采用HYPERMESH对各部分分别进行网格划分，然后提交给Abaqus赋予各部件材料模型，完成部件之间的装配连接，并定义边界条件和载荷。其边界和载荷为：工字梁侧端面的6个自由度均被约束住；施加在引轮、定子、转子环上的扭矩以及加在曳引轮上的压力通过耦合到中间轴的方式进行加载。 累计仿真分析座椅系统项目 100+ 累计仿真分析天窗系统项目 200+ 累计仿真分析电动尾门系统项目 100+ 累计仿真分析玻璃升降机系统项目 200+ Get Started Business Right Now!

					<description><![CDATA[复合材料是由有机高分子、无机非金属或金属等几类不同材料通过复合工艺组合而成的新型材料，它既能保留原组分材料 的主要特色，又通过复合效应获得原组分所不具备的性能。可以通过材料设计使各组分的性能互相补充并彼此关联，从而获 得新的优越性能，与一般材料的简单混合有本质的区别。 复合材料的运用Case 风电叶片强度计算分析 叶片设计中要进行风力空气动力学计算和结构力学计算。叶片的外形是通过空气动力学设计确定的，尺寸较复杂，而且其尺 寸、表面光洁度以及质量分布等都有较高要求。叶片的结构形式是通过结构力学计算确定的，常见形式为设有加强筋的空腹薄 壁和薄壁泡沫塑料夹芯结构。确定合理的结构，以防止在受载离心力、弯矩和扭矩时失稳或局部变形。 飞机模态分析 模态是机械结构的固有振动特性，每一个模态具有特定的固有频率、阻尼比和模态振型。这些模态参数可以由 计算或试验分 析取得，这样一个计算或试验分析过程称为模态分析。在根据自然状态下飞机的模态分析，提飞机 的一阶频率值及相应模态振 型，避开飞机引擎的共振频率，解决飞机的共振问题。 发动机罩盖轻量化设计 针对某车型的发动机罩板结构，在不改变几何外形的前提下采用替换发动机外罩板材料的方法，进行了普通钢板发动机罩盖 和自动铺丝复合材料发动机罩盖行人头冲击有限元模拟，研究了不同材料发动机罩板结构在行人头冲击下的吸能特性。采用复 合材料替换传统钢板材料可实现发动机罩盖减重39%。 累计仿真分析座椅系统项目 100+ 累计仿真分析天窗系统项目 200+ 累计仿真分析电动尾门系统项目 100+ 累计仿真分析玻璃升降机系统项目 200+ Get Started Business Right Now!

					<description><![CDATA[汽车安全性（automobile safety）汽车在行驶中避免事故，保障行人和乘员安全的性能，一般分为主动安全 性、被动安全性、事故后安全性和生态安全性。在道路交通事故中，汽车本身的安全性能也是不可忽视的因素。 汽车安全性能好，往往可以避免事故的发生或减少伤亡的程度。主动安全就是尽量自如的操纵控制汽车。无论 是直线上的制动与加速还是左右打方向都应该尽量平稳，不至于偏离既定的行进路线，而且不影响司机的视野 与舒适性。这样的汽车，当然就有着比较高的避免事故能力，犹其在突发情况的条件下保证汽车安全。 被动 安全是指汽车在发生事故以后对车内乘员的保护，如今这一保护的概念以及延伸到车内外所有的人甚至物体。 汽车碰撞安全的运用Case C-NCAP碰撞测试 C-NCAP碰撞测试包括 正面100%重叠刚性壁障碰撞试验、正面40%重叠可变形壁障碰撞试验、可变形移动壁障 侧面碰撞试验。通过这几项碰撞测试的得分，再加在一起总的分数，来给定出碰撞星级。 鞭打分析 运用混三50%TH的假人进行座椅的鞭打实验，首先确认HP点的坐标吻合，量测头部和座椅头枕的水平位移，把座椅 调整到中间位置，以每小时15.6公里速度进行碰撞，加速度峰值到达10G. 仪表盘碰撞分析 汽车仪表由各种仪表、指示器，特别是驾驶员用警示灯报警器等组成，为驾驶员提供所需的汽车运行参数信息。模拟 实车在碰撞过程中假人对仪表板的碰撞强度分析，来验证仪表板的结构合理性。 累计仿真分析座椅系统项目 100+ 累计仿真分析天窗系统项目 200+ 累计仿真分析电动尾门系统项目 100+ 累计仿真分析玻璃升降机系统项目 200+ Get Started Business Right Now!

					<description><![CDATA[多学科设计优化是一种充分探索子系统相互作用的复杂系统设计方法论，多学科设计优化最早是由美国国家航空航天 局（National Aeronautics and Space Administration ,NASA）高级研究院、现任美国航空航天学会（American Institute of Aeronautics and Astronautics,AIAA）多学科设计优化技术委员会主席Sobieszczanki-Sobieski提出，是一种探索子系 统相互作用的复杂系统设计方法论。通过探索和利用系统中相互作用的协同机制，利用多目标策略和计算机辅助技术来 设计复杂系统及子系统，可以有效缩短设计周期，获取系统整体最优性能。 多学科优化的运用Case 白车身多学科多目标优化 设计变量涉及了结构梁位置、角度、截面尺寸、板厚、材料等58个参数，以满足包括白车身刚度、模态、100%刚性墙碰 撞、40%偏置碰撞、侧撞等在内的多个设计目标。通过分析可以找出对各项性能有较大的影响的白车身设计参数，同时发现各性能指标随工程更改可能出现的变化趋势，这对项目后期针对工程问题做出正确的决定非常重要。同时了解白车身满足各设计目标的最大减重可能以及保持设计成本时的最大产品设计潜能，并可以在多个目标值之间进行权衡分析，以对设计空间进行全面深入的了解 扭梁悬架多学科优化设计 为了缩短产品开发周期提高产品的竞争力，通过产品模型同时优化产品的各方面性能变得越重要。扭梁悬架的设计过程 中就要求同时满足多方面的性能，像动力学特性、结构强度特性等。但是现有的多学科共同设计方法耗时很长，因为重复 工作效率非常低。通过统计表明自动化集成优化要比手动每一个方面单独优化节省80%的时间.多学科集成优化技术的本质 是模型数据在集成系统中每一个CAE分析软件中被确认、传递和求解，最后经过判断得到满足所有性能要求的优化模型。 累计仿真分析座椅系统项目 100+ 累计仿真分析天窗系统项目 200+ 累计仿真分析电动尾门系统项目 100+ 累计仿真分析玻璃升降机系统项目 200+ Get Started Business Right Now!

									<p>多学科设计优化是一种充分探索子系统相互作用的复杂系统设计方法论，多学科设计优化最早是由美国国家航空航天 局（National Aeronautics and Space Administration ,NASA）高级研究院、现任美国航空航天学会（American Institute of Aeronautics and Astronautics,AIAA）多学科设计优化技术委员会主席Sobieszczanki-Sobieski提出，是一种探索子系 统相互作用的复杂系统设计方法论。通过探索和利用系统中相互作用的协同机制，利用多目标策略和计算机辅助技术来 设计复杂系统及子系统，可以有效缩短设计周期，获取系统整体最优性能。</p>								</div>

									<p>为了缩短产品开发周期提高产品的竞争力，通过产品模型同时优化产品的各方面性能变得越重要。扭梁悬架的设计过程 中就要求同时满足多方面的性能，像动力学特性、结构强度特性等。但是现有的多学科共同设计方法耗时很长，因为重复 工作效率非常低。通过统计表明自动化集成优化要比手动每一个方面单独优化节省80%的时间.多学科集成优化技术的本质 是模型数据在集成系统中每一个CAE分析软件中被确认、传递和求解，最后经过判断得到满足所有性能要求的优化模型。</p>								</div>

					<description><![CDATA[多体系统动力学是研究多体系统（一般由若干个柔性和刚性物体相互连接所组成）运动规律的科学。多体系统动力学包括多刚 体系统动力学和多柔体系统动力学。虽然经典力学方法原则上可用于建立任意系统的微分方程，但随着系统内分体数和自由度的 增多，以及分体之间约束方式的复杂化，方程的推导过程变得极其繁琐。 为适应现代计算技术的飞速发展，要求将传统的经典力 学方法针对多体系统的特点加以发展和补充，从而形成多体系统动力学的新分支。为建立多体系统动力学的数学模型，已经发展 了各种方法，其共同特点是将经典力学原理与现代计算技术结合。这些方法可归纳为两类，即相对坐标方法和绝对坐标方法。 多体系统动力学分析涵盖建模和求解两个阶段，其中建模包括从几何模型形成物理模型的物理建模、由物理模型形成数学模型的数 学建模两个过程，求解阶段需要根据求解类型（运动学/动力学、静平衡、特征值分析等）选择相应的求解器进行数值运算和求解。 多体动力学科的运用Case 登机门结构多体分析 虚拟样机技术是当今先进的机械设计、分析理念和发展方向，随着计算机硬件和软件技术的不断发展，以多体系统动力学为核心的 虚拟样机动态仿真技术逐步应用到飞机设计中。在某型飞机的登机门设计中，由于采用门梯合一设计，门部件间的运动关系十分复杂 ，因此机门能否有效开启和关闭是机门设计中的主要设计因素。本文采用多体动力学软件MotionView搭建该登机门多虚拟样机模型， 得到相关的力和力矩，为登机门设计参数的优化以及后期的疲劳和强度提供参考依据。 副车架MotionView分析 副车架作为重要的支撑和承载部件，其强度和疲劳寿命直接影响乘员的安全，在开发过程中需要重点关注。传统的开发过程要先试制样件或是样车，然后通过整车道路试验和台架试验对设计方案进行反复验证，耗费大量的时间和金钱。随着计算机仿真技术 的发展，通过CAE分析对设计进行验证被普遍应用到汽车开发过程中。本文通过使用多体动力学分析软件MotionView对某在开发的副车 架进行了分析，以验证设计方案结构强度，并将分析结果与台架试验结果进行对比，两者基本吻合。 风电系统多体分析 多体系统的模拟在新兴的风能工业中是相对较新的部分。由于长达20年的设计生命周期，所以表征性的结构模型试验只能基于有限 的基础上进行。对于现实的模拟在产品的研发过程中是一个非常重要的环节。风力发电机的转动系统是一个集成化高又很昂贵的装置。 传动系统制造商，风机制造商和认证机构一直致力于把一个可靠的设计推向实践。设计的关键之一就是传动链的动态性能，它在确定 局部载荷和机械部件的物理特性上起到了重要的作用。 累计仿真分析玻璃升降机系统项目 200+ 累计仿真分析天窗系统项目 200+ 累计仿真分析电动尾门系统项目 100+ 累计仿真分析玻璃升降机系统项目 200+ Get Started Business Right Now!

					<description><![CDATA[CAE在生物医疗领域中的分析问题通常包括生物固体力学、生物与生理流体力学、细胞生物力学、康复工程力学、运动系统 力学等。而随着仿真分析技术水平的不断提升以及国内外研究学者对医疗事业的不断重视，在上述的五个方面从试验和仿真分 析以及解析计算三方面有了很大的发展，尤其是在仿真分析方面，不论是材料本构的开发，还是仿真手段的创新都有许多的新 发展。由于CAE仿真的可重复性、高效率和通用性，广受研究者们的青睐。弗艾科技在上述多个领域均具备实际CAE仿真经验， 形成了完整的生物医疗领域CAE解决方案。 生物医疗的运用Case 骨骼应力 植入到人体内部的人造髋关节，膝盖，脊椎骨，以及其它骨骼部件都面临着巨大的挑战，这其中包括诸如更多人造骨骼的材料 特性，人体生理学，外科手术过程和人造骨骼的制造工艺等方面的问题。利用CAE分析，来避免行业风险，提高认识，加快在医药 行业的发展。 血管类分析 由于心脏是一个神秘和复杂的器官，对于治疗心血管疾病的医疗专业人员面临着动力学方面的挑战。医生们已经能够通过使用 可植入设备和非可植入设备解决一系列心脏衰弱疾病。可植入式的心脏设备，例如支架，线圈和心脏瓣膜，以及非可植入的心脏 设备，正在根据他们的产品规格变得日益复杂和严格。 足部计算分析 在任何足矫正和外科手术之前，都必须对正常脚的生物力学有正确的认识。脚和踝中应力和应变的分布信息是对脚踝复合体认 识的提升。对于脚和踝的复杂体的运动和载荷分布，试验是昂贵和困难的。有限元方法允许对脚和软组织之间的关节运动和载荷 分布的预测，进行有效的载荷条件，结构和材料变量分析。 Get Started Business Right Now!
