abstract
nowadays it is known that there are some difficulties，such as lower energy
rate and inadequate work capacity in the exca*vating process for hydraulic
exca*vator because of conventional exca*vating parern and it is very important
for hydraulic exca*vator with high energy consuming from engineering machine,s
how to realize optimum and intelligent control in exca*vating process．in order to
minish directly exca*vating resistance and energy consuming of hydraulic
exca*vator and enhance work雒iciency and self-adaptive capacity,some main
research task in this paper such as seeking after a reasonable and effective
exca*vating method for soil and process optimization modeling and intelligent
control strategy of hydraulic exca*vator are completed based on applying
vibratory theory to soil exca*vating process for hydraulic exca*vator and using
theory analysis and experiment research combinatively,and the research fund is
obtained from ‘‘863 research fund[2003aa430200]"(namely
mechanics．electronics and manufacture informatization of hydraulic exca*vator)
and ‘‘program for new century excellent talents in
university'’[ncet-05-0697]．the main works of the paper are expressed as"

(1)the characteristic of static intensity and dynamic intensity were studied
and exca*vating principle and invalidation mechanism to soil were discussed．the
simulation experiment results about crashing rock and soil process based on
dynamic load receal that vibratory impact function dynamic ioad can improve
force method of shovel blade and miilish exca*vating resistance in a big way,
therefore，rock and soil call be destroyed even if its stress lower than its
destructive intensity．

(2)in allusion to fact cites of noise jamming of exciting force signal from
the buchet inevitably and the characteristic of noise from exciting force signal in
the vibratory exca*vating process for hydraulic exca*vator，imf weight of signal
based on the wideband random noisy background is processed using soft
threshold method and a signal denoising algorithm for noisy signal is given
based on emd method．the simulation results reveal that the signal denoising
algorithm can enhance decomposing veracity of exciting force signal from the
buchet，time effect property of extracting instantaneous parameters and can
remove a*vailably noise jamming of exciting force signal from the buchet．
