A method of approximating spring characteristic and its application to the problem of balancing input torques

스프링특성의 근사법과 입력토오크 평형문제에의 응용

An efficient method for designing balancing springs to be used for dynamic balancing of planar mechanisms was studied. In spite of its wide application in the field of balancing problems such as balancing of input torques, clearance effects etc., there have been few efficient ways of determining the specifications of the balancing springs. To improve this problem, a method of approximating the characteristic of linear springs was suggested and its validity was checked through an analysis of errors. Further, through an example of a balancing problem to reduce the fluctuation of input torques of a 4bar mechanism, it was shown that the proposed method of approximation simplifies the design equations and a satisfactory result can be found efficiently.

본 연구에서는 실제적인 평형스프링을 비교적 단순한 계산에 의해 설계할 수 있는 방법의 하나로서, 선형스프링의 근사법을 제시하였으며, 이 근사법을 4절 기구의 입력토오크 특성의 향상문제에 적용하여 유용한 결과가 얻어짐을 보였다.
