Since about 1925, use of steel in car bodies of rolling stock for passenger transportation has become popular in Japan. To check the increase of weight resulting from it to the possible minimum, the strength calculation of the side frame of the car body became necessary, and in 1927, Mr. Suzuki proposed a method. Since then the study of strength calculation of the side frame of a car body has become accelerated, because of increased need for lightweight cars and introduction of test methods resulting from appearance of the wire strain gauge. A car body is subjected to such external forces as (1) bending due to self-weight and load (shearing too, at the same time), (2) torsion and (3) tension and compression in the longitudinal direction. Therefore, the strength calculation of a car body has to be made with regard to these loads.
