Title the whole design of the loader ZL05
Abstract
Loader is one of the main models of the engineering machines. The homework efficiency is high. The topic of this design is the total and its work equip of the loader ZL05. The main contents of this design is as follows:
The total calculation and analysis of the loader. It includes the choice of launch the machine parameter, the assurance of the whole machine function parameter, the choice of the theories leads characteristic parameter, the analysis of the theories leads characteristic parameter, the calculation of the theories leads characteristic parameter, the evaluation of the total parameter ,the calculation that the machine spade packs resistance, the whole machine of self-respect and the bridge lotus allotment, the calculation of the biggest lead the dint, the calculation of the biggest climb a slope.
The design of work equip, including the choice of the spade type, the assurance of orders' position, the assurance of the length to moving arm,shake arm and pulling the pole, the assurance of cutting the noodles shape, working equip's analysis by dint and the school check strength, the calculation of the pulling pole stability .
The analysis and calculation of the liquid presses system, including the work liquid to press the system design parameter and the pressure calculation, the discharge calculation of the oil urn's needing, the choice of the oil pump, the choice of the liquid presses, the calculation of changing direction a liquid to press system of minimum turn radius, change direction resistance and work a pressure.
The front and back car connects and craft request.
In addition, I build up the model of this loader's work device in ADAMS and carry on sport to imitate really, I also test to find out its biggest the unloaded height and the curve of spade point's moving﹑velocity and acceleration.
Keywords the total calculation and analysis work equip the liquid presses system car connects
