    摘要:

    為了給虛擬樣機(jī)仿真分析提供復(fù)雜三維路面環(huán)境,，基于單點(diǎn)FFT路面不平度時域模型,，建立了三維FFT隨機(jī)路面數(shù)學(xué)模型,，并實(shí)現(xiàn)了其在Matlab中的仿真；依據(jù)三角網(wǎng)格法理論,，建立了生成三維路面文件的通用模型,，包括節(jié)點(diǎn)的生成和單元生成算法，并導(dǎo)入Adams形成所需的三維路面仿真環(huán)境,。應(yīng)用上述方法生成C級路面,，對所選擇的車輛樣機(jī)進(jìn)行了行駛平順性仿真,，與GB/T 13441—92標(biāo)準(zhǔn)對比分析得到了該車行駛平順舒適性的合理時間,。

    Abstract:

    In order to provide the research of virtual prototype a complex 3-D virtual road environment, a 3-D FFT stochastic road model was established based on the single-point FFT model, and then the simulation result was gained by Matlab. What's more, based on the theory of triangle network, a general 3-D virtual road model with the arithmetic of nodes and elements was created. Then a specified 3-D virtual road file was imported into Adams to form the 3-D virtual road. Finally, a C-level virtual road was generated for the riding performance simulation of virtual vehicle. By comparing the simulation result with the GB/T 13441—92, the virtual vehicle's reasonable time under the ride performance requirement was obtained.
