概要:
application/pdf<br />Journal Article<br />This paper deals with a method for solving dynamic stress problems of a non-cylindrical viscoelastic coil spring subjected to base excitations. The analysis considers the effects of ends of the
…
coil, and applies the three dimensional curved beam theory for obtaining the exact solution of the element of the coil. The resultant forces and the resultant moments in the vibrant coil are decided by means of the transfer matrix method for an arbitrary shape. Both the shear and the normal stresses are obtained by use of the curved beam theory as just mentioned. Numerical calculations have been carried out for two cases of a barrel spring and a hyperboloidal spring.

概要:
application/pdf<br />Journal Article<br />This paper is concerned with the method for analyzing the vibration of coil springs with arbitrary shape. In the analysis, the field transfer matrix is derived from the solution of the
…
foundamental equation of the curved beam theory. The transfer matrix is given by combining this field transfer matrix and the point transfer matrix. The analysis derives the frequency equation which is applicable to the coil spring of general shape. Numerical calculations have been carried out for HYPERBOLOIDAL springs and barrel springs. Experimental tests are also carried out to verify the present theoretical results.
