Research And Exploitation On Bridge-inspection Vehicle

Along with development of highway traffic,the amount of bridges increases rapidly,one side it creates favorable transportation condition for economy development,on the other side, many bridges become aged by time so that many traffic accidents happened due to the aged problem.Thus,examining and repairing on bridges become a very important task.National economy and traffic construction develop at very fast speed,requirement for bridge-inspection vehicle mushroom by bridge maintenance department,bridge-inspection vehicle is prepared to fit development of society and science advancement,at the same time,it adapt current market economy and new situation.Bridge-inspection vehicle cant not only repair bridges' damage but also assure bridges on the safe side,still it can be used to pave establishment such as electric power and communication cable.etc under bridge bottom.at one time,it has termly maintenance and overhaul functions.Bridge-inspection vehicle is a special large-scale equipment for bridge measure and maintenance,it's make up of automobile chassis special device and control system it offers Platform Units to workers at any moment to move to suitable position rapidly and safely.In the fowling decade,highway and bridge construct will still keep rapid develop speed.in our country.R&D on bridge-inspection vehicles are still in primary phase, bridge-inspection vehicles mostly are imported,therefore,bridge-inspection vehicles have a very wide market.Therefore,R&D on bridge-inspection vehicle have very important meaning.This text make research and study on bridge-inspection vehicle,refer to an overseas antetype vehicle, the major contents as follows:(1)bases on bridge-inspection vehicle given parameter and related documents,make sure collectivity project and the arm frame;(2)modeling CATIA entity for the arm frame of bridge-inspection vehicle,also analyze the movement,spread order and configuration theory drawings;(3)study out hydraulic pressure theory chart for bridge-inspection vehicle,analyze hydraulic pressure on framework and discuss how to select action action components;(4)use CATIA software to make dummy assemble about arm frame parts and validate design rationality;(5)discuss application of mechanism kinematics emulation software ADAMS on the Platform Units,and how to build model in ADAMS in order to make preparation for emulation.
