| Recent 10 years, because of the construction the realm expands continuously, having already taken place the very big variety in the specification to the need of the engineering machine product, miniature machine of significant rising of demand, get the favor of more and more customers.More and more value to raise the machine utilization and emphasize the engineering efficiency etc. the factor all promoted to the need of the miniature machine.The miniature machine is easy to the carrying, being free from the restrict, flexibility good, and the function be no more inferior to than the large machine, this is the very important characteristics, this perhaps is to urge more factories house one of the reason that produces the miniature machine. The small glide type loader is a widely used engineering machine. It is used toLoad bulk material, clean space and make short Distance transportation.It is also used To make slight excavation work.If its bucket is re placed by other working device,the loader can also be used to finish many tasks. contain very high operation function, make operation is easy to the operation and is easy to maintain, the safety credibility; The fast liquid presses to deal with contact and can make additional device carry on replace in several seconds. I t has many advantages, such as it hasSmall volume,its weight is slight,and it is very mobile,Etc..It is often used to clean Bulk material in small building places and other narrow space such as cabins.Skip loader is also called the multi-function engineering vehicle, it is an kind of wheel loader having the proprietary chassis, it uses the difference line speed of wheel on the two to realize the turning of the vehicle, it adopts wheel walking organ, the multi–wheel driving, skip turning, can change or hang all kind of working devices in the working space quickly and randomly to adapt different working environment and working contentThe power of skip loader is about 20～50kW, the quality of main machine is 2000～4000kg,the vehicle speed is about 15km/h. The skip loader is mainly used in the working space where is very narrow and the ground is rough, and it can also be used as the assistant facility for large engineering machine. The whole exterior size is small, and can realize turning in the same (quondam) place. In the future, the foreground of the skip loader is the improvement of manipulating function, relieve the handled intensity of the driver's.In this thesis, I have forecasted the market foreground of skip loader, analyzed its static hydraulic pressure transmission working theory and character, mainly done the Finite Element and Emulating Analysis of working device.skip loader's working device is arm-frame-four- poles device, take the loader for example, establish the FE model, use the ANSYS to analyze the static configuration and intensity, get the integrated distribution of stress and distortion. In addition,the author uses the fi nite element software( SAP91)to compute the Stress of moving arm and Analyze the ersul Use the ADAMS to do mechanical movement dynamic Emulating Analysis of working device. The results of research can be used in the practice, so the thesis have very high practical reference value.
