HLS is the sec­ond-gen­er­a­tion light source with en­ergy of 800 MeV and emit­tance of less than 40 nm-rad. In order to im­prove the beam orbit sta­bil­ity and cor­rect the er­rors in­tro­duced in the or­bital feed­back sys­tem due to move­ment of the vac­uum cham­ber and BPM, a sys­tem for mea­sur­ing BPM dis­place­ment will be built. It re­quires a high de­gree of me­chan­i­cal and ther­mal sta­bil­ity for its sup­ports. The sup­port should have a higher eigen-fre­quency to min­i­mize the am­pli­fi­ca­tion of ground vi­bra­tion. In this paper, a se­ries of sim­u­la­tion, in­clud­ing fi­nite el­e­ment analy­sis (FEA), mea­sure­ment and analy­sis have been done upon the sup­port to make sure it can meet the re­quire­ments of the sta­bil­ity of the BPM dis­place­ment mea­sure­ment sys­tem.
