    摘要:

    為計算分析履帶車輛傳動系統(tǒng)扭轉(zhuǎn)隨機激勵,，以標(biāo)準(zhǔn)路面不平度統(tǒng)計特征為基礎(chǔ),，實現(xiàn)路面激勵時頻轉(zhuǎn)換,。同時分析扭轉(zhuǎn)隨機激勵產(chǎn)生機理,，提出其理論計算公式，并且通過對相關(guān)部件模型的數(shù)學(xué)抽象,，建立不同路面下履帶整車動力學(xué)模型,。通過實例仿真得到某履帶車輛扭轉(zhuǎn)隨機激勵譜，探討了路面不平度,、車速和預(yù)張緊力對其產(chǎn)生的影響,。研究結(jié)果表明，路面不平度和車速是影響扭轉(zhuǎn)隨機激勵的主要因素,。

    Abstract:

    To analyze the torsional random excitation of tracked vehicle powertrain system, the road surface excitation was transferred from frequency region to time region based on given the statistical characteristics of road roughness. The root of torsional random excitation was investigated and theoretic calculating formula was proposed. Then the dynamics model of tracked vehicle was constructed under different road surface by abstracting each element of the vehicle mathematically. The torsional random excitation spectrum was numerically calculated. The effects of road roughness, vehicle velocity and pretension having on torsional random excitation were deeply studied. The investigated results indicated that the road roughness and tracked vehicle speed were the main factors to determine the value of torsional random excitation.
