第一篇:
铁路是国家的重要基础设施、国家的大动脉、大众化交通工具。在综合交通体系中处于骨干地位,没有铁路的现代化就难以实现国家的现代化。近年来,随着我国国民经济的快速发展,铁路行业也取得了巨大的发展,但是与其他行业的发展相比,虽然经过五次大提速,但是仍然满足不了各行各业对铁路运输的要求。为了我国铁路事业的发展,提高机车车辆动力学性能是其最主要的方面之一。
本文详细介绍了机车动力学基本原理以及利用ADAMS软件进行整车模型的建造以及针对机车垂向振动的动力学分析过程。通过应用ADAMS软件仿真机车垂向悬挂系统进行多目标、多参数优化(如采用较软的二系弹簧和较硬的一系弹簧)可以降低车体的垂向振动位移和加速度。通过对机车振动模型的分析计算,寻找出影响机车振动的关键参数,并通过调整系统结构、参数,使机车振动在允许的范围内。

第二篇:
随着经济的快速发展,互联已经成为人们快速获取、发布和传递信息的重要渠道,它在人们政治、经济、生活等各个方面发挥着重要的作用。随着互联网的发展,网络已逐渐成为人们工作和生活的好帮手。目前全国网民总数已达到1.5个亿,这表明网络已经成为人们学习生活中必不可少的一部分。
旅游网站是基于Intranet(企业内部网)、Extranet(企业外部网),拥有自己的域名,由若干个相关的网页组成的网页组,在服务器上存储一系列的旅游信息的Web站点。使用者可通过旅游网站的浏览器浏览所需要的旅游地信息。它是利用网络技术,从旅游专业角度,整合传统旅游资源,提供全方位多层次的网上旅游服务的场所,是旅游信息系统的传输媒介。旅游网站的服务功能包括:旅游信息的汇集、传播、检索和导航;旅游产品和服务的在线销售;个性化服务(在线预定服务)等。
本文通过使用颇具影响力的Macromedia公司的网站制作利器——Dreamweaver8来架设一个小型的旅游网站。本网站属于资讯类网站,具体功能有旅游景点信息的汇集、出游行程推荐、访客留言交流以及为一个多月前的汶川大地震专设的“加油中国”祈福板块。留言板还设有管理员后台管理功能,已实现对留言的筛选与评论。
请不要用金山等翻译工具,需要准确的翻译,谢谢了,加高悬赏!!!快点帮忙啦!!

Railway is the country's vital infrastructure, the country's main artery, the popular means of transport. In the integrated transport system in a key position, not the modernization of the railway will be difficult to achieve the country's modernization. In recent years, with the rapid development of China's national economy, the railway industry has made tremendous development, but with the development of other industries than five times the speed despite, but still can not satisfy all sectors of rail transport requirements. China's railway to the development, improve the rolling stock of its dynamic performance is one of the most important aspects.
This paper describes the basic tenets of motorcycle dynamics and the use of ADAMS software model vehicle for the construction of locomotives and vertical vibration analysis of the dynamic process. ADAMS simulation software through the use of locomotive suspension system for vertical multi-objective, multi-parameter optimization (such as the use of soft and hard spring of a spring) can reduce the body's vertical vibration displacement and acceleration. Through the analysis of the vibration model locomotive, the locomotive impact vibration to find the key parameters, and by adjusting the structure, parameters, the vibration in the locomotive to the extent permitted.

The second:
With the rapid economic development, the Internet has become a fast access, publish and disseminate important information channel, which people in the political, economic, and other aspects of life plays an important role. With the development of the Internet, the network has gradually become people work and live a good helper. At present, the total number of Internet users has reached 1.5 billion, this shows that people learning network has become an essential part of life.
Travel site is based on the Intranet (intranet), Extranet (enterprise extranet), have their own domain name, from a number of relevant pages of the website group, on the server storage of a series of travel information Web site. Users can travel through the site the browser need to travel information. It is the use of network technology, professionals from the tourism perspective, integrating traditional tourism resources to provide comprehensive multi-level online travel service establishments, travel information system is the transmission medium. Travel site services include: Survey of tourist information, communication, search and navigation; tourism products and services online sales; personalized services (line booking services).
Through the use of influential Macromedia's weapons production sites - Dreamweaver8 to set up a small tourist site.
