Zoomlion pump truck vibration reduction technology has made breakthrough progress

Guide: Recently, through the joint cooperation of the technical research center of the engineering technology center of the concrete machinery company, the electrical group of the electrical control technology company and various departments of the branch company, the active vibration reduction technology of the pump truck boom has achieved good results in the practical application of a series of products, marking Zoomlion's success in the boom vibration control technology

recently, through the joint cooperation of the technical research center of the engineering technology center of the concrete machinery company, the electrical group of the electrical control technology company and various departments of the branch company, the active vibration reduction technology of the pump truck boom has achieved good results in the practical application of a series of products. Taking another gasket to repeat the above steps marks that Zoomlion has made a breakthrough in the boom vibration control technology, which has not been effectively recycled for many times

when the vibration reduction technology is applied to the pump truck, the vibration amplitude at the end of the pump truck boom is not more than 200mm within the full working condition range, and the vibration displacement amplitude at the end of the pump truck boom is reduced by more than 60%. The small vibration amplitude, nicknamed "overview of the global composite market - intersection of 10 words", has been unanimously praised by the majority of customers

since the invention of the concrete pump truck, the construction inconvenience and safety hazards caused by the large-scale vibration at the end of the boom have never stopped. In order to solve this problem, the engineering technology center of the concrete machinery company set up a special project team to tackle this problem, and finally developed a set of boom vibration control system with completely independent intellectual property rights

the system integrates CIFA boom dynamics modeling and boom vibration modeling technology of domestic industry, and explores a new rigid flexible hybrid vibration modeling method of pump truck boom, which greatly improves the calculation efficiency and accuracy of boom vibration response simulation. A dynamic characteristic identification method of pump truck boom based on test data is realized, which can quickly and accurately provide the vibration characteristics of pump truck boom. After a series of tests such as no-load, pump water, site assessment and so on, the vibration reduction of the pump truck under multi attitude has achieved good results, making it meet the requirements and achieve good results. The application of this technology provides strong technical support for the development of Zoomlion long boom pump truck and strengthens the core competitiveness of the company's concrete pump truck

at present, this vibration reduction technology has been applied to Zoomlion concrete pump truck with remarkable results. The project team of the branch company is improving the algorithm and optimizing the program through a series of experiments, with a view to applying the vibration reduction technology to various series of concrete machinery products, and the generalization of the technology on various types of pump trucks is just around the corner
