摘　　要：对自行式载重车悬架组群系统进行了顺应性描述和顺应效果评价,针对目前传统的液压弹簧悬架系统,设计改进了一种自适应悬架组群系统,建立了整车和自适应悬架组群系统的非线性数学模型;在额定载荷为3200kN的两纵列六轴线自行式载重车的基础上,以随机路面激励为输入,在空载和满载工况下建立了液压弹簧悬架系统和自适应悬架组群系统的仿真模型。仿真分析和现场试验对比结果表明,改进后的自适应悬架组群系统在空载和满载工况下顺应系数分别提高了103.8%与55.1%,系统液压缸输出力更加平缓,具有更好的顺应性,采用改进后的自适应悬架组群系统的自行式载重车在行驶过程中的抗冲击振动能力和改善车辆平顺性方面效果显著。Through the descriptions and effect evaluations of the compliance of self-adaption suspension group systems in self-propelled transporters,a kind of self-adaption suspension group system was improved and designed in view of the present traditional hydraulic spring suspension system,and a nonlinear mathematical model of the transporter and self-adaption suspension group system was established.Based on the six axis of self-propelled transporter which was loaded 3200 kN,the simulation model of hydraulic spring suspension system and self-adaption suspension group system was built with random road surface excitation for inputs under no-load and full load conditions.Simulation analyses and field tests show that the compliance coefficient of the improved self-adaption suspension group system is increased by 103.8% and 55.1% under no-load and full-load conditions respectively,the output forces of the system hydraulic cylinder are more gentle and the compliance performance of the system is better.The ability to resist shock vibrations and the performance to ride comfort improvements have remarkable effects in the self-propelled transporter driving processes using the improved self-adaption suspension group system.
