| 概要 |
A flat carriage is a vehicle type without a body and a roof for transporting goods, designed to meet the needs of heavy goods. Several conceptions are elaborated, with respect to capacity of 57-ton re...commended to 2x20 feet containers. The aim of the paper follows determining the strength and durability of the flat carriage under operational loading at accordance with the required criteria and using a fatigue limit diagram approach based on the Soderberg method. This research was conducted with static and dynamic tests. The sections for 50 strain gauges were indicated based on data from to the finite element method. The results showed that in the case of vertical static loading, the maximum stress on the flat carriage structure occurred at full vertical load (50,050 kg) in the end centre sill area, at single measuring location no. 24, with a value of 59.8 MPa, and the results of the static test were still below the allowable stress of the material at 243.8 MPa. Meanwhile, at the dynamic loading conditions, the greatest stress occurred at single measuring location no. 24 with mean stress value of 59.7 MPa, stress amplitude was 17.8 MPa, and at single measuring location no. 23 with mean and stress amplitude values of 59.6 MPa and 34.4 MPa, respectively. The results of the analysis showed that the mean stress value (σ_mean) and amplitude stress value (σ_amp) were still below the fatigue limit curve of the Soderberg diagram. From the results of this research, it was concluded that the 57-ton flat carriage prototype construction/structure, under static and dynamic loads, can be manufactured as many as operational needed.続きを見る
