the paper investigates into the vibrational characteristics of the truck chassis including the natural frequencies and mode shapes. truck chassis forms the structural backbone of a commercial vehicle. when the truck travels along the road, the truck chassis is excited by dynamic forces caused by the road roughness, engine, transmission and more. modal analysis using finite element method (fem) ...

One of the most important steps in development of a new truck chassis is the prediction of fatigue life span and durability loading of the chassis frame. The age of many truck chassis in Malaysia are of more than 20 years and there is always a question arising whether the chassis is still safe to use. Thus, fatigue study and life prediction on the chassis is necessary in order to verify the saf...

This paper presents the stress analysis of heavy duty truck chassis. The stress analysis is important in fatigue study and life prediction of components to determine the critical point which has the highest stress. The analysis was done for a truck model by utilizing a commercial finite element packaged ABAQUS. The model has a length of 12.35 m and width of 2.45 m. The material of chassis is AS...

This review presents a thorough survey of academic work on the chassis design by FEA and application of design of experiment method in it. It surveys most literature published in English language. The review aims to provide insight into the truck chassis design and act as a guide for researchers working on both FEA and DOE method for chassis design. The main objective of the design is to obtain...

The three-dimensional model of 2500hp shale gas fracturing truck chassis frame was established and the natural frequency of the frame was obtained by modal analysis. Taking the displacement power spectrum density of a typical road as a random excitation, the random vibration response of frame was obtained by PSD module of finite element analysis software ANSYS. Based on the results of PSD analy...

–Under-running of passenger vehicles is one of the important parameters to be considered during design and development of truck chassis. Rear Under-run Protection Device (RUPD) plays an important role in avoiding under-running of vehicles from rear side of a truck. In India, the legal requirements of a RUPD are fixed in regulation IS 14812-2005. To reduce number of iterations during the develop...
