Design Of The Structure Of The Truck Mixer And Digital Simulation Of Its Hydraulic System

The truck mixer is a vehicle for transportation concrete. It is fulfilled two actions, conveying concrete and mixing concrete. These actions not only ensure the quality of the concrete, but also make the conveying distance longer. But in the northwest area of our country, research on the field of the truck mixer is little. So the truck mixer must be developed strongly in order to meet the need of the rising concrete market. Three important parts are studied in this thesis. Firstly, the helix-vanes of the truck mixer are designed following the principles of the flowing state of the concrete on the helix-vane. Secondly, the drum of the truck mixer is designed base on its working characteristic. Thirdly, with the widely used soft ware package SIMULINK the mathematic models of the hydraulic system driving the truck mixer are established on the found of the theory and method of power bond graph. The dynamic characteristics of the hydraulic system are simulated numerically, and some significant results are presented.
