Abstract


With the growing shortage of energy , wind power is becoming a research focus and energy of high-tech hot spots . Intertidal areas of wind power equipment transportation technology solutions and engineering background , summarized summarize the development status of the multi- tracked vehicles at home and abroad , combined with the Dalian University of Technology , Dalian DHI · DCW Group Co., Ltd. the cooperative development LYC150 crawler transporter project examples , the use of multi-body dynamics theory and hydraulic system simulation theory of multi- tracked vehicle modeling and simulation, experimental study and analysis of the impact factors . The main research contents are as follows : ( 1 ) In accordance with the technical requirements of the vehicle , the scheme of the crawler transporter structure of the program , working principle and the hydraulic system ; RecurDyn (2 ) multi- tracked vehicle dynamics modeling , detailed driver wheel , guide wheel , supporting wheels and tracks key components of the modeling process and the establishment of multi - tracked vehicles and ground dynamics model ; ( 3) the AMESim of a key component in the hydraulic system , such as closed hydraulic pump hydraulic motors , such as modeling, simulation model established on the basis of multi - tracked vehicle closed hydraulic system ; (4) based on RecurDyn AMESim software co-simulation , and running test carried out for the crawler transporter , comparative analysis of test results simulation results verify the correctness of the multi- tracked vehicle virtual prototype ; (5 ) the impact of multi- tracked vehicle steering performance factors were analyzed , and the working pressure of the hydraulic systems that track gauge , track hinge point distance track shoe width . Through the above research , the paper gives the establishment of multi- tracked vehicle dynamics model and hydraulic system model by testing to verify its correctness , while taking advantage of the virtual prototype model of the factors that affect the multi- tracked vehicle steering performance analysis , which concluded the theoretical analysis and technical reference for the multi- tracked vehicle R \u0026 D optimization .
