Abstract

The invention relates to a multipoint local pretightening method for adjustable load sharing mechanisms, which belongs to the field of a sensing test method and a sensing test device. The method realizes multipoint local pretightening by adjustment of a pretightening screw to drive a pretightening slider, and realizes adjustment of structural parameters through a mounting length adjustable measuring rod. The multipoint local pretightening method adjusts the length of the measuring rod according to the actual demand of measurement and assembly, performs multipoint local pretightening force adjustment, and makes the measuring rod exerted by the pretightening force. The device adopted comprises six groups of adjustable load sharing mechanisms with the same structures, wherein each group of adjustable load sharing mechanisms consist of an upper platform, a lower platform, the pretightening screw, the pretightening slider, an upper connecting rod, a lower connecting rod, an upper round nut,a lower round nut, an upper connecting flange, a lower connecting flange, a group of piezoelectric quartz sensors and a positioning ring. The multipoint local pretightening method realizes multipointlocal pretightening and adjustment of the structural parameters, and has the characteristics of good pretightening effect, strong large-load sharing capacity, convenient assembling operation, high precision, good stability and simple structure.
