摘要
提出了一种在室内利用物理仿真试验测试拖拉机阻力控制系统动态性能的新方法。建立了拖拉机阻力控制室内动态仿真试验系统。论述了仿真试验原理和模拟加载装置的设计要点。以东风-50型拖拉机为例,给出了阻力控制系统动态消扰特性仿真试验结果。
A new method of using physical simulating test to measure the dynamic performance of tractor draught control system is presented.A dynamic simulating test system of tractor draught control in laboratory is developed.The principle of simulating test and the key to designing loading simulating device are discussed.As an example,the results of simulating test on the dynamic anti-disturbance characteristics of Dongfeng- 50tractor draught control system is introduced.
