Embodiment 1

[0040] The vehicle cab frame structure optimization method of the present embodiment comprises the following steps:

[0041] A. Construct the vibration transmission path analysis model for the cab-frame structure entity to be optimized. Taking the driver's seat as the response point, construct the vibration transmission path analysis model of the total system, the vibration transmission path analysis model of the frame subsystem and the cab sub-system respectively. The system vibration transfer path analysis model is tested to obtain the transfer function and working condition data of the total system and two subsystems, analyze the vibration contribution and frequency response of each transfer path in the total system and two subsystems, and determine the overall system and two subsystems. The vibration paths and key frequencies with large contributions in the two subsystems are used as the optimization target path;

[0042] After the transmission path analysis in this embodi...

Abstract

The invention aims to provide a vehicle cab frame structure optimization method which comprises the following steps: A, a transfer path analysis model is built, the vibration path contribution amountis obtained, and the frame target path is determined; B, solid model input preset motivation is tested, and the actually measured acceleration value is obtained; a finite element model is built, and asimulation acceleration value and all direction simulation error coefficients are obtained; C, the actual optimization total target acceleration value is set, and the actual structure optimization target acceleration value is calculated; the error optimization parameter is preset, and the total cut-down target value is calculated and analyzed; the simulation structure optimization target acceleration value is calculated; D, an equivalent cutting rate model is built, and the frame target path acceleration value is calculated; E, the optimization area of the finite element model is subjected totopological optimization, and the finite element model of the optimized cab frame structure is obtained. According to the method, the defects that the prior art is not comprehensive and the blindnessis large are overcome, and the method has the advantages that the pertinence and the optimization efficiency are high.

Description

technical field [0001] The invention relates to the field of vehicle structure design, in particular to a vehicle cab frame structure optimization method. Background technique [0002] Low-speed trucks are widely welcomed because of their high cost performance. They are characterized by strong adaptability, large load capacity, and good reliability in harsh conditions such as rural dirt roads and muddy roads. However, with the continuous improvement of living standards, people have put forward higher requirements for comfort while paying attention to cost performance and reliability. Users report that the shaking of the steering wheel will easily reduce the driver's sense of control over the direction; the vibration of the instrument panel will make it more difficult for the driver to see the operating data of the vehicle; the vibration of the seat will easily cause the driver's fatigue; The driver misjudged the situation outside the vehicle. In addition, according to the ...
