摘要
根据傅里叶变换和逆变换的相关理论,利用matlab编制了模拟路面不平度激励的程序,计算出了时域路面不平度激励;利用ADAMS建立了牵引车的虚拟样机模型,以得到的时域路面不平度激励为基础,反求出了牵引车车架的动态外载荷的时间历程。为获取车架的疲劳寿命和进一步研究车架动态特性提供了依据和参考。
According to the theory of Fourier transform and inverse transform,using matlab prepared a simulated road roughness incentive program,calculated the time-domain road roughness incentive;Established the tractor virtual prototype model by using ADAMS,reversed out the dynamic loads history of the tractor frame based on the road roughness motivation. Provided basis and reference for obtaining frame fatigue life and further research on the frame dynamic response.
