摘　　要：阐述了手扶机动插秧机液压仿形系统的功能、特点、设计依据、动态分析、数字仿真及评价指标。系统主要功能是控制机架摆动范围，主要特点是在尽可能节能情况下，考虑支承缓冲及非线性流量增益。用相对运动合成观点建立控制系统数学模型，牵连运动惯性力作为干扰影响动态过程，在数字仿真中作为多输入量之一，一并考虑。The functions,distinguishing features,dynamic analysis and applications of digital stimu-lation of hydraulic position control system for a walking type transplanter are discussed.Highlights of the design are the considerations of lowest energy consumption, elastic supportand nonlinear flow gain. The main function is to control the chassis pitching range.Themathematical model in this research is built from the viewpoint of compound motion.The in-ertial force of base motion affects the dynamic process and is considered as a factor of distur-bance in the multivariable inputs in digital stimulation.
