In order to avoid the potential risk of damage caused by the hammering during the assembling operation of Marman Clamp, an alternative method to unify the tension in the Marman Clamp bands is proposed. The method is to eliminate the effects of friction, which is the cause of the tension nonuniformity, by slightly sliding the clamp block when the band pre-tension is set. In order to confirm the effectiveness of the method, the Marman Clamp of an upper-stage inter-stage joint of Mu-3SII satellite launcher was assembled with and without the application of the present method, and the stain distribution was measured. The comparison of the data clearly indicated the effectiveness of the proposed method.
