摘要
本文通过讨论路面不平度的特点和数学机理,在分析路面不平度作为各态历经的平稳随机过程中,将从空间域内的平稳随机过程,变换到时间域内的非平稳随机过程的算法,作为设计计算的边界条件。
The property and numerical principle of road roughness is introduced in this paper. As a stable ergodic gaussian stochastic process, the transformation of road roughness is studied from stationary random process in time domain to nonstationary random process in spatial domain, which will be an actual boundary condition to vehicle simulation analysis.
