摘要
在研究路面谱测量原理过程中发现,平稳过程自谱密应度的运算有两个值得探讨的问题。经过仔细推导得出正确的表达式,与ISO8608及GB7031-86取得一致的效果,从而为第五轮测量路面谱计算公式的建立奠定了基础。
When studying the measuring Principles of road surface spectrum it is concluded that two problems are worth discussing in calculations of stationary process autospectral density. Based on meticulous derivation, the correct expressions are obtained and as consistent with the results of ISO 8608 and GB7031-86. There fore the study provides a basis for setting calculation expressions in measurement of road surface spectrum by means of fifth wheel.
