Abstract To solve the problem of vibration in the disc separator for drip irrigation of Yellow River water-mud,the calculation and test of whole machine full speed dynamic balance of disc separator are carried out based on the influence coefficient method.The separator is fitted at the testing rig,with test spots on the top botton of bearing.The equation is the informal complex linear equation when the number of testing spots is more than that of correction planes.Conjugate transpose matrix equation is multiplied by the original equation to get the corresponding complex equations.The new equation is resolved by the method of main element elimination in the complex field.The equalized complex numbers in all adjusting planes are transformed into vectors.The approximate optimization solution of equalizing weight is calculated by programming.The specialties of resolving approximate optimization solution of inconsistent equations by the least square method are analyzed. The result shows that the balance based on method of influence coefficient method has better effects,which make the separator vibration restrained and operating effectively.
