【Abstract】 The transverse lost stability about the pressing screw spring is very important. There are many classic results about the stability of column screw spring with circle section but few reports can be gotten which column screw spring with rectangle section lost stability. Critical conditions have been established for the lateral failure of column screw spring with reed thread rectangle section using the comparative rigidity theory with the sheering force effect taken into consideration. Many meaningful results have been gotten under the critical conditions for column screw spring with reed thread column section small rising ange.更多还原
