Base On Emulation Part Of Load 450t Fall Holl Car To Manufacture

As China's economic and technological development, grew up on a big load of special sharp increase in demand for trucks, heavy-duty vehicles 450t hole down the development of key technologies is of great significance. In this paper, because of the heavy-duty truck load 450t down hole larger, the main structural components such as side-Cheng Liang, Liang-oriented, chassis, chassis in the small chassis, such as structural strength requires careful study and analysis. The structure of the car and the car is very different from the past, its dynamic performance to reconsider.This article first use of the finite element method for heavy-duty truck load 450t down hole larger, the main structural components such as side-Cheng Liang, Liang-oriented, chassis, chassis in the small chassis, such as strength and stiffness were calculated, and the static strength test, with the aim of the vehicle through the imposition of simulated static load of goods Test and re-run the test car, load measurement 450t fall in the hole vehicles rated under the load, the major components of the vehicle static and dynamic stress and deformation in order to determine the vehicle's structural strength and stiffness is to meet TB/T1335-1996 "rolling stock Strength and design Identification Test Standards "(hereinafter referred to as the" norm ") and the car design book.The evaluation Test of the main parts for heavy-duty 450t hole down the side of the car Cheng Liang, Liang-oriented, chassis, chassis in the small chassis, and the sub-rod, bar and so on the next. And then their performance dynamics simulation carried out to further validate the vehicle's wheel and rail security and stability to meet GB/T17426 -1998 "special railway line of rail vehicles and machinery dynamics and the assessment of the performance test method" standards.
