Research On Steering System Of WTW420B Seavy Platform Truck

WTW420B heavy platform truck mainly is based on the large-scale equipment, it is the high tech product which is the integration of machine-electricity-hydraulic technology, the computer communication and so on.Heavy platform truck has the multi-patterns to change independently, to walk generally, the frame hydraulic pressure adjusts the equal function. In which heavy platform truck steering system control technology is in the heavy platform truck the most core most complex part., how to realize the whole truck from multi-pattern turn to controls, and guarantee the synchronism and responsiveness of the whole system. It is playing an important role in the development of whole WTW420B heavy platform truck. This article mainly aims at each large-scale ships factory the actual situation, changed the control system to the WTW420B heavy flatbed to conduct the research.In the article first introduces the operational principle of steering system for WTW420B heavy platform truck, which based on PID control principle; aim at the specific situation of WTW420B heavy platform truck and the problem of steering control system that about synchronism and responsiveness have been researched.. Resolve the problem how to turn the multi—patterns of heavy platform truck to turning controls. Finally has carried on the summary to the entire research process. This vehicle develops successfully, provides the very good model and the experience for the larger-scale platform truck development accumulates; because simultaneously this product definitely may substitute the import, therefore has had the huge social efficiency and the economic efficiency.
