In terms of the transmission shaft balancing, it exists another problem that the shaft is not looked at as rigid body.When the rotor running at a high-speed ,under the action of unbalance force ,the transmission shaft will bend. It is certainly ideal to balance a transmission shaft as a flexible rotor.However, considering the mass production of automobiles, this method is obviously unpractical. In order to discreasing the flexible deformation, in this theory, the feasibility that double- plane balancing takes method the place of multi-plane balancing on a special place for one segment transmission shaft.
从传动轴平衡的角度来看,传动轴并非刚体,在汽车高速旋转时,由于不平衡力的作用会使传动轴发生挠曲,如果将传动轴作为挠性转子进行平衡当然比较理想,但是不符合汽车大批量生产的实际,为减少挠曲振动,利用挠性转子平衡原理,对于单根传动轴,从特殊位置进行校正,从而以二面平衡代替多面平衡是可行的。

In this thesis the process of constructing the non-perturbative Hamiltonian theory is de-scribed and is applied to estimate the vacuum condensate. It contains the following contents:At the very beginning, by using the path integral method and eliminating the gluon freedom, aGCM action 〓 of current quarks including lower order current-current coupling was derivedfrom the QCD Lagrangian and the effective Hamiltonian operator that could hardly be doneby the normal methods was derived. After doing this, the broken vacuum is introduced whichincludes quark-antiquark condensate through the generalized Bogoliubov-Valatin transformation,the effective Hamiltonian of constituent quark was derived. The detailed formulas containingthe spatial current-current coupling term for the effective Hamiltonian and gap equations wasworked out by parameterizing the correlation kernel as a quadratic potential. And then, the gapequation was solved and the quark-antiquark condensate of vacuum was studied both in the casesof instantaneous interaction and retarded interaction. In the end, the effective Hamiltionian withtwo-body quark-quark interaction was derived with one-body approximation, and with the helpof the functional integral method the coupling non-linear dynamic equations for systems withnuclear matter was derived. Finally, these equations were solved by selfconsistent method andthe effect of nuclear matter on vacuum condensate was studied. The spatial current-current coupling term is too difficult to handle, hence the correlationkernel is assumed to be not important and usually omitted in the pure vacuum condensate, andthe instantaneous interaction generally is adopted. Retaining the spatial current-current termand partial retardation effect, the quark pairs condensate in pure vacuum was studied, and theeffect of quark mass was also studied. At present, little study is focused in the case with nuclearmatter and spatial current-current term also omitted. Under the approximation with partialspatial current-current term, the effect of nuclear matter on vacuum condensate was studied.
