In order to improve the operational reliability of the lines and substations , power industry generally regular cleaning of insulators to increase the insulator flashover voltage . For the Robotics Institute of Shanghai Jiaotong University Lanzhou Power Supply Bureau , by the Robotics Institute of Shanghai Jiaotong University - based research to develop a 220/330kV pressure charged cleaning robot for cleaning of insulators . The project has been funded by the National 863 fund . With the terrorist crime growing , using explosives, acts of terror have been common . And the types of explosives and scale are increasingly diverse . Demand in order to better adapt to the EOD , Shanghai Jiaotong University multifunction anti-terrorism EOD integrated equipment concept and preliminary design . Above both context and open up this topic . The four-wheel drive trailer of this research can be used as a \The subject of the four-wheel drive trailer the overall analysis and design . Analytic Hierarchy Process , from the the Wheel front axle drive with clutch , clutch, wheel front and rear axle drive with three options crawler wheeled front and rear axle drive with clutch mechanical structure best suited to the system . Four structure of the four-wheel-drive system: the frame system , drive system , the body and the clutch system , trailer brake system . MCU, DSP and PLC are three commonly used control method selected PLC as the control strategy . PLC and inverter communication . And the design of the hydraulic system was described and analyzed.
