| Abstract: | A model of state space of main-value assembly for tractor in lifl is de-rived from power key diagram method.With the aid of digital simulation and ex-periments the authors study time domain response of main-valve assembly and dynamic variation in system pressure during lifting.It is pointed out that the dy-namic performance at the closed moment of return-oil valve will have an impor-tant effect on lifting ofthe tractor suspension system. |
