EFFECTS OF THE TYPE OF JOINTS BETWEEN THE LONGITUDINAL AND CROSS MEMBERS ON THE RIGIDITY OF THE COMMERCIAL VEHICLES CHASSIS FRAME

This research is dedicated to the study of the effect of the type of joint fastening between longitudinal and cross members on the rigidity of the chassis frame. A model of one joint of the chassis frame, between the longitudinal and cross members was constructed to carry out the laboratory experiments where the load was increased in steps and the resulting deflections were measured in the case of using high tensile bolts or using hot rivets.

Effect of Transverse Load on Energy Absorption of a Vehicle Frame During Accident

A finite element model was introduced to simulate the experimental data of an axially loaded column subjected to a transverse load. The model was validated and proved to be in good correlation with the experimental results. The model was further used to investigate the effect of applying a transverse load on axially loaded members of a vehicle frame.

Closed Section Steel Tubes Axial Crushing and Energy Absorption Behavior

This paper presents the effect of design parameters on crushing behavior and energy absorption of steel tubes used in bus frame manufacturing. Experimental investigations were carried out on different cross sections steel tubes subjected to axial impact load. Experimental tests were repeated on three sets of previously mentioned tubes, dents and holes were added to tubes to evaluate its effect on energy absorbed by those tubes.
