Types of Bridges Any number of different methods may be used to classify bridges. Bridges can be classified according to materials (concrete, steel, or wood), usage (pedestrian, highway, or railroad), span (short, medium, or long), or struc- tural form (slab, girder, truss, arch, suspension, or cable-stayed). None of these classifications are mutually exclusive. All seem to contain parts of one another within each other. For example, selection of a particular material does not limit the usage or dictate a particular structural form. On the other hand, unique site characteristics that require a long-span bridge with high vertical clearance limit the choices of materials and structural form. Experience, modeling, peer review, public review, architectural review, and landscape review all may play important roles in selection of a bridge type. Contractor experience, traffic control, construction methods are addi- tional considerations. Designers seldom select a bridge type ba

外文原文 Mechanical Design Abstract：A machine is a combination of mechanisms and other components which transforms transmits. Examples are engines, turbines, vehicles, hoists, printing presses, washing machines, and movie cameras. Many of the principles and methods of design that apply to machines also apply to manufactured articles that are not true machines. The term 'mechanical design' is used in a broader sense than 'machine design' to include their design. The motion and structural aspects and the provisions for retention and enclosure are considerations in mechanical design. Applications occur in the field of mechanical engineering, and in other engineering fields as well, all of which require mechanical devices, such as switches, cams, valves, vessels, and mixers. Keywords: Mechanical Design； Mechanisms Design Process；Application 1. The Design Progress Designing starts with a need real. Existing apparatus may need improvements in durability, effi

Integrated Knowledge-Based System for Machine Design Abstract An integrated design system (IDS) approach has been developed to integrate various stages of the mechanical design process, including rapid prototyping. The system consist, of design, analysis, calculation, rapid prototyping, and library modules, and it blends artificial intelligence methods, CAD-CAM, and technical computing packages into a single environment. The system has been applied for the design of one-stage gearbox with helical gear. In this case study, all stages of the design process are carried out by using IDS. 1. Introduction The design process of the mechanical products is tedious and time consuming because of the various stages and complex activities involved. On the other hand, there are strong pressures to reduce overall costs in a competitive market environment . But, the traditional design approach is inadequate in meeting these needs. Today a lot of CAD/CAM/CAE application software, dif

1. STEERING SYSTEM. Directive D 70/311 is one of the oldest and requires that any motor vehicle, with more than 25 km/h as maximum speed and with at least four wheels, be equipped with a steering system; this rule applies also to trailers, but not to rail vehicles, agricultural and earth-moving machines. For the steering system, the Directive means any device having the function of changing the driving path of a vehicle. It includes: bull; the control (the steering wheel) bull; the transmission from the control to the steering wheels bull; steering wheels bull; any device suitable for producing auxiliary energy for assistance; this auxiliary energy can be mechanic, hydraulic, pneumatic or any combination of the above, including energy storage. Three categories of vehicles are identified with: bull; manual steering, where steering energy is supplied by the driverrsquo;s muscle power only; bull; power steering, where this energy is partly supplied by th

It starts out as an idea . The idea is combined with money , and a project is born . The project is developed as drawings and specifications . It is then built . When it is complete , it is turned over to the owner as a finished facility and is occupied , maintained ,and repaired as it ages and eventually dies . A facility can last for hundreds of years , but the period in which it is actually designed and built is very small . At some point in its lifetime a facility is likely to be renovated , either to renew obsolete syst

Recently the heavy truck industry has experienced a large push to develop vehicles with reduced cost and weight. This has been a major challenge for truck manu- facturers as they look for ways to optimize their vehicle designs without sacrificing durability or performance. Since the truck frame is a major component in the vehi- cle system, it is often identified for refinement. This paper outlines a computer aided engineering (CAE) procedure for analyzing changes to the truck frame and how these changes affect vehicle performance. The frame of a heavy truck is the backbone of the vehicle and integrates the main truck component systems such as the axles, suspension, powertrain, cab, and trailer. The typical frame is a ladder structure consisting of two C channel rails connected by cross-members. The frame rails vary greatly in length and cross-sectional dimen- sions depending on the truck application. Likewise, the cross-members vary in design, weight, complexity, and cost. These

Automatic production line PLC control of automatic feeding station Automatic production line is composed of the workpiece transmission system and control system, a set of automatic machine and auxiliary equipment in accordance with the process sequence, completion of all or part of the manufacturing process production system, automatic line for short. The 20th century 20 s,as car, rolling bearings, small motor and sewing machines and other industrial development, machinery manufacturing industry began to appear in automatic production line, the first is the modular machine tool automatic line. In the 1920 s, first appeared in the automotive industry running water production line and semi-automatic production lines, and then developed into the automatic production line. After the second world war, in the machinery manufacturing industry in developed countries, the number of automatic production line has increased dramatically. Adopt the products of the automatic production li

63.1 Introduction 63.1.1 Historical Evolution With a recorded history of about 5000 years, China has a vast territory, topographically higher in the northwest and lower in the southeast. Networked with rivers, China has the well-known valleys of the Yangtze River, the Yellow River, and the Pearl River, which are the cradle of the Chinese nation and culture. Throughout history, the Chinese nation erected thousands of bridges, which form an important part of Chinese culture. Ancient Chinese bridges are universally acknowledged and have enjoyed high prestige in world bridge history. They can be classified into four categories: beam, arch, cable suspension, and pontoon Bridges. The earliest reference to the beam bridge in Chinese history is the Ju Bridge dating from the Shang Dynasty (16th to 11th centuryB.C.). During the Song Dynasty (A.D. 960 to 1279), a large number of stone pier and stone-beam bridges were constructed. In Quanzhou alone, as recorded in ancient books,
