Compaction is efficiency method that base material intensity and stability is improved.Compaction can improve in effect bearing the weight of soil and not pervasion,in more complexion,compaction construction is best basic construction method,it is applied a lot of construction work..The in-vehicle compaction meter can detect the compaction degree of the soil continuously, During vibratory roller compaction work, vibratory wheel-soil system's dynamical parameter will change with soil dynam capability's transformation,soils damp and rigid of transformation have osculation relation.During vibratory roller compacting soil,soil's rigid will augment with vibratory roller compaction work,and soil's damp will reduce with vibratory roller compaction work. Soil's rigid of accretion means soil compaction degree's accretion. This paper attempt to expound vibratory wheel's acceleration and complexion of soil's compaction degree.Through argumentation analysis this connection,we will offer theoretics base for in-vehicle compaction meter testing soil's compaction degree and testing soil's compaction degree by indirectly testing transformation of vibratory wheel's acceleration.Method that this paper adopted will calculate system's displacement and acceleration response by analyzing vibratory wheel-soil system's dynamical equation with modal analysis. Working out vibratory wheel-soil's system's speed, displacement, acceleration's extent and connection between them under simple harmonic motion .Through comparing displacement breadth of vibratory wheel-soil system's dissimilarity soil's compaction phase,we will get soil's compaction degree of transformation complexion of dissimilarity soil's compaction phase.At same time,we adopt MALTAB/SIMULINK emluator displacement that procedure computed With dummy experiment validate soil's compaction degree transformation,and through expounding vibratory wheel acceleration signal put forward designing project of vibration wheel vibration acceleration wireless gather system。...
