AI Technical Summary

Technical Problem

The prior art is difficult to comprehensively and objectively evaluate the smoothness of heavy trucks, especially the lack of assessment of cab shock absorption and chassis shock absorption capabilities, which makes it difficult to quantify optimization and increase the difficulty of adjustment.

Method used

By defining the general goal of the smooth and smooth truck of heavy trucks, it is split into sub -leisions, the smoothness of the cab, and the chassis smoothness of the seat, establish an evaluation index system for progressive multi -level structures, and build a judgment matrix to in order Extract the weight of the index and conduct smooth evaluation of the vehicle.

Benefits of technology

It improves the objectivity and accuracy of multi-level shock-absorbing ride comfort evaluation of heavy-duty trucks, enables a comprehensive assessment of vehicle ride comfort, supports design optimization, and improves driving performance and ride comfort.

Abstract

The invention provides a heavy truck multistage damping smoothness evaluation method, system and device, and belongs to the technical field of vehicle smoothness evaluation, the vehicle smoothness total target of a heavy truck is defined, and the vehicle smoothness total target is divided into at least one sub-target; establishing evaluation indexes corresponding to the sub-targets based on the progressive multi-layer structure, and forming an evaluation system; the evaluation system comprises but is not limited to a seat ride comfort index evaluation system, a cab ride comfort index evaluation system and a chassis ride comfort evaluation system; and constructing a judgment matrix corresponding to the evaluation system, extracting an index weight in the judgment matrix, and performing vehicle smoothness evaluation based on the index weight and the evaluation index. According to the method, the seat smoothness, the cab smoothness and the chassis smoothness can be comprehensively evaluated, and the problem that optimization of a cab shock absorber and a chassis shock absorber is difficult to objectively quantify is solved. The evaluation precision is ensured and the evaluation requirements are met.
