					<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[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[分析软件可以进行多种功能分析，其解决问题的范围从简单的线性分析到复杂的非线性分析都可胜任，软件包含丰富的单 元库，可以模拟任意几何形状的单元库和材料性能，结构分析是其重要组成部分，这就决定FEA的操作界面不同于结构 设计软件。结构设计软件的功能目标很明确，就是为了给结构工程师提供施工图终端服务的，各种界面设置都是围绕工程师 关心的事情出现的，再配合“傻瓜式”的服务理念，大部分的功能都集成化，也符合结构工程师的思维模式，因此结构设计软 件的应用非常直接而广泛。 不同的结构设计软件可能在界面上有差异，但菜单设计是按照结构工程师的设计思路排序的，有 经验的工程师可以不经过训练就可以通过软件操作进行施工图没计。 土木建筑的运用Case 山顶观光塔的强度分析 造型独特带来强烈的视觉冲击力，在结构的设计中，进行最大载重的静态分析，评估可行性。 连接强度分析 钢管混凝土柱与钢梁连接点处的应力分析，该处结构形式复杂，应力状况也比较复杂，需要研究钢材和混凝土之间的协同作用。 Get Started Business Right Now!
