Simulation And Optimizing Of Hydraulic Excavator's Working Equipment

A excavator is good or not depending on it's performance of working equipment. Digging performance chart is a importance means to evaluate the design of a excavator. But it is very difficult to drawing a digging performance chart, and chart isn't convenience to be used. Today the computer technology is developping so fast, the CAD technology invade to manufacturing's heart, and the CAE technology start to pervade to manufacturing enterprise. CAD/CAE/CAM melt into together become a trend. The melt wil improve repetition of CAD's data. This article's purpose is to use the mainstream software implement to explore a way which can be used to evalute a excavator's performance, the way is easy to be understood and is visual. It can be used to evaluate the digging performance.The article finish the work as below:(1) At first the article introduce the principle of excavator how to work. then accord to digging condition, discussing the principle ought to be followed at design. The article get the conclusion that match between cylinders ought to consider firstly the cylinder's diameter, while the cylinder's stroke ought to meet required range of whole excavator's. (2) Bring forward a optimizing object of the digging force and working efficiency in specifing range that depend on the cylinder's diameter. And deduce the formula in ADAMS to computed digging force. So the software can be use to compute static of really excavator. (3)Build model for ADAMS-Matlab combine simulation. Accord to ADAMS's advantage is in dynamic computing and Matlab's advantage is in programming, combine them through interface to make digging force visualized, so digging force at any point in working range can be indicated through drawing picture. (4)Take for a example to compute digging force and optimizing the cylinders diameter.
