| The Demolition Robot is one kind of industrial robot, which is applied to the architectural demolition, the rescue and relief work, cement, metallurgy, nuclear energy and so on. With the development of society, the application scope of the Demolition Robot is more and more wide. The hydraulic system is its core, which will transmit the power for each load installation and have the important influence to each load's movement, therefore it has the decisive influence to the whole machine performance. So it has the significant theoretical meaning and practical value to research it deeply.In this paper, firstly the introduction to the present developing situation and trend of the Demolition Robot at home and abroad is analyzed in detail. It proposes two different hydraulic system schemes and analyzes them. On the basis of comparison and conclusion, the hydraulic system of the Demolition Robot was determined. This hydraulic system is multi-actuator parallel load sensitive hydraulic system with load sensitive installation. Secondly, this system's parameter is determined on the basis of the related parameter of small excavator. And the working, rotary and walking device of the Demolition Robot is carried on to design calculation and hardware election. Lastly, on the basis of introduction to the simulation problem of hydraulic system, this paper put its emphasis on the introduction of the structure composition, characteristic and applied field of AMESim simulation software. Making use of AMESim simulation software to model and simulate the hydraulic system on the basis of the reasonable simplification and supposition to the hydraulic system of the Demolition Robot. Obtaining the systemic response characteristic curve by simulation and then analyzing the results of simulation provide the theoretical evidence to the hydraulic system project of the Demolition Robot. |
