In this dissertation, according to the theory of mechanical dynamics and multi - body dynamics, a simulation model of nj2046 light off - road vehicle including suspension system, steering system and tires is built with the software carsim and so the vehicle steering characteristics are analyzed with the step angle input of steering wheel. it is found that the steering characteristics are different when the velocity and load are different, and the relationship between steering characteristics and velocity and load is presented
本文根據機械繫統動力學、多體動力學理論，運用動力學模擬軟體carsim建立了包括懸架系統、轉向系統和輪胎等模型的nj2046越野汽車整車模擬模型，在此基礎上分析了nj2046越野汽車在方向盤轉角階躍輸入時的轉向特性，通過對不同車速、不同載荷條件下的模擬計算，得出了在這些條件下該車具有的不同表現特徵，揭示了轉向特性與車速、載荷和輪胎的內在關系。 -
Input pulse signal can be directly transformed into micro - step linear motion by use of linear pulse motor, which have found wide applications in the digital linear servo systems with high positional accuracy and high reliability. taking slpmu - 025a, a two - phase hybrid lpm manufacturing by shinko motor company ltd, as an specimen, the study on the drive control system is carried out in this thesis, which contains : ( l ) three kinds of drive circuits are designed and comparison analysis in theory is done ; ( 2 ) introduction to at89c51 microchip as controller and special micro - step constant current driver, a great variety of running modes driver control are developed ; ( 3 ) experimental testing and theoretical analysis of current waveforms and displacement graphs and velocity graphs are carried out in case of different micro - step constant current driver
