| Tractor backhoe is all important type of construction machinery. The quality and effect of the design of its working mechanism determine, to a large extent, the working properties of the loader. Traditional design methods arc no longer capable of solving complicated engineering problems. Nowadays, with the development an application of CAD technology and modem design methodology, especially optimization design, the design of construction machinery is becoming more and more automated and intelligent. Both working mechanism and modeling methodology are presented manifold. The research work focuses on the following aspects:The work characteristic of tractor backhoe has been introduced. The kinematic analysis of the working mechanism has been made. getting conditions that must be satisfied during its operation, such as performance, working scope, efficiency, power transmitting properties, kinematic properties, geometric relations, strength, etc.With variables, objectives, and constraints determined respectively, the optimization design has been carried out. Characteristics and application scope of each type are analyzed and verified with ADAMS.The article applied AUTODESK INVENTOR there-directions-design's technology to achieve there-directions-design's model of the life-pole, clear express to the there-directions structure of the lift-pole, for later, we would calculate the strengthen of the lift-pole, design and advance the structure to create all kinds of conditions. |
