18×4车简化模型某型8×4载货车在以65km/h匀速行使时,经常出现剧烈的整车共振问题。而整车共振问题的产生是由于整车的共振频率与某一外界激励的频率达到一致时的一种外在表现。下面就8×4车整车共振频率与各种外界激励频率的产生机理加以说明。图18×4车简化平面模型图1为8×
18 × 4 car simplified model A type of 8 × 4 truck at 65km / h uniform speed, often severe car resonance problem. The vehicle resonance problem is due to the resonance frequency of the vehicle with an external excitation frequency to achieve an external manifestation. The following 8 × 4 car vehicle resonance frequency and a variety of external excitation frequency to explain the mechanism. Figure 18 × 4 car simplified plane model Figure 1 is 8 ×
