    摘要:

    根據(jù)輪胎力學場的數(shù)值分析結果,采用傅里葉級數(shù)擬合單元在輪胎滾動一周內的應力應變變化,,利用傅里葉級數(shù)系數(shù)計算輪胎單元損耗應變能與生熱率,。通過正交驗法設計臺架試驗,,測試了不同速度,、載荷,、胎壓和環(huán)境溫度下輪胎不同部位的溫度,,以驗證數(shù)值分析結果,。對應臺架試驗方案各工況,模擬了斜交胎在不同工況下的穩(wěn)態(tài)溫度場分布,數(shù)值計算結果與試驗值基本一致,。在此基礎上討論了環(huán)境溫度,、速度、載荷,、胎壓等因素對輪胎溫度的影響,并給出了胎肩最高溫度與各因素之間的關系公式,。

    Abstract:

    Fourier series was utilized to fit the stress and strain of tire in a rolling cycle by means of mechanic-field analytic result. Element dissipation energy and heat generation rate were calculated according to the obtained Fourier coefficient. The orthogonal experimental method was used to design the roadwheel test scheme. The temperature at the different locations was measured at the case of the different velocity, loads, inflated pressures and air temperatures and the referenced basis was offered to verify the validity of numerical analytic result. Steady temperature field was simulated at the different cases corresponding to each case of roadwheel experiments and the results were basically consistent with the experimental data. The influences of environmental temperature, velocity, load, inflated pressure on the tire temperature distribution was discussed. The equation of relationship between the maxim temperature of tire shoulder and all influences factors was offered.
