【摘要】：針對煤礦井下大噸位鉸接式自卸車因承載重、外形大、重心高等因素導(dǎo)致行駛穩(wěn)定性降低的問題,為對穩(wěn)定性進(jìn)行評估和優(yōu)化,提出了"穩(wěn)定角"的評價指標(biāo),并根據(jù)車輛在煤礦井下的工作條件,制定了穩(wěn)定性準(zhǔn)則。通過建立車輛橫向一級、二級失穩(wěn)狀態(tài)的幾何模型,推導(dǎo)出穩(wěn)定角的計算解析式,運用MATLAB軟件編程計算了穩(wěn)定角,因橫向一級穩(wěn)定角不滿足穩(wěn)定性準(zhǔn)則要求,對整車軸距、輪距、滾動半徑及重心位置等參數(shù)進(jìn)行了優(yōu)化設(shè)計,經(jīng)計算,優(yōu)化設(shè)計后橫向一級穩(wěn)定角滿足了準(zhǔn)則要求,其余穩(wěn)定角指標(biāo)也提高約10%。
[Abstract]:In order to evaluate and optimize the stability of large tonnage articulated dump truck in coal mine, the stability is reduced due to the factors of heavy load, large shape and high center of gravity, etc. In order to evaluate and optimize the stability, the evaluation index of "stability angle" is put forward. According to the working conditions of the vehicle in the coal mine, the stability criterion is established. By establishing the geometric model of the lateral and secondary unstable state of the vehicle, the analytical formula for the calculation of the stable angle is derived, and the stable angle is calculated by using the MATLAB software. Because the lateral first-order stable angle does not meet the requirements of the stability criterion, the wheelbase of the whole vehicle is obtained. The parameters of wheel spacing, rolling radius and center of gravity are optimized. The calculation shows that the horizontal first order stable angle meets the criterion requirement, and the other stability angle indexes are increased by about 10%.
