摘　　要：基于有阻尼简谐惯性力激励的受迫振动原理,对一种偏心振动压实式筑埂机的传动路线及其偏心振动压实筑埂结构等关键部件进行设计,使用adams仿真软件对筑埂机的偏心振动压实装置作业工况进行模拟仿真,对其由于质量分配不均匀、弹簧加工误差所引起的偏振现象进行分析,最后对其振动装置下的弹簧刚度系数、阻尼系数进行优化。将adams与edem耦合进行仿真试验,模拟其筑埂机在田间作业时的工况,对作业的进行速度进行了仿真实验分析。仿真对比实验证实,相较于传统筑埂机,偏心振动筑埂田埂坚实度提升约500 kPa。田间试验对比,可见偏心振动压实式筑埂机所筑田埂的坚实度提升效果明显,弥补了传统筑埂机在所筑田埂方面坚实度不足的缺陷,进而验证了仿真试验的可靠性。Based on the principle of forced vibration excited by damped harmonic inertial force,this paper designs an eccentric vibration compaction ridge building machine,describes its working principle,transmission route and design of key components such as eccentric vibration compaction ridge building structure in detail,and simulates the working condition of eccentric vibration compaction device of ridge building machine by using ADAMS simulation software,and analyzes its quality.Finally,the spring stiffness coefficient and damping coefficient are optimized.Adams and Edem are coupled to simulate the working condition of the ridge building machine in the field,and the speed of the operation is analyzed.Through the simulation and contrast experiment,it is concluded that compared with the traditional ridge building machine,the ridge firmness of the eccentric vibration ridge building machine is improved by about 500kPa.Through the field test comparison,it can be seen that the firmness of the ridge built by the eccentric vibration compaction type ridge building machine is obviously improved,which makes up for the lack of firmness of the traditional ridge building machine,and further verifies the reliability of the simulation test.
