Problems solved by technology

However, when the wide-body dump truck operates on the harsh road surface of the mine, the actual load on the frame is complicated and difficult to calculate.
At present, the load calculation method that is widely used is to simulate the frame strength calculation load by multiplying the empirical dynamic load coefficient and the load-bearing mass, or loading the forced displacement at the connection point between the frame and the suspension. This loading method is simple and rough, and the calculation results It cannot reflect the actual force of the frame very well, so it cannot provide correct design guidance for the frame structure design

Abstract

The invention discloses a method for calculating load of an off-highway dumper frame, which comprises the following steps of: for a working condition without load transfer, carrying out suspension load taking by using a suspension dynamical model, and for a working condition with load transfer, taking load of a dumper by a whole vehicle dynamical model. The actual load of the frame can be accurately obtained, a reasonable boundary condition is provided for calculation of the strength of the frame, and the problem that the load is inaccurate during calculation of the strength of the frame is avoided.

Description

technical field [0001] The invention relates to the technical field of frame load simulation calculation. More specifically, the present invention relates to a method for calculating frame loads of off-highway dump trucks. Background technique [0002] Wide-body dump truck frame is an important bearing part, and its reliability is crucial to the service life of the whole vehicle. However, when the wide-body dump truck operates on the harsh road surface of the mine, the actual load on the frame is complex and difficult to calculate. At present, the load calculation method that is widely used is to simulate the frame strength calculation load by multiplying the empirical dynamic load coefficient and the load-bearing mass, or loading the forced displacement at the connection point between the frame and the suspension. This loading method is simple and rough, and the calculation results It cannot reflect the actual force of the frame very well, so it cannot provide correct des...
