Decomposition analysis platform and decomposition analysis method for whole vehicle performance indexes of commercial vehicle

Abstract

The invention discloses a decomposition analysis platform for whole vehicle performance indexes of a commercial vehicle. The decomposition analysis platform comprises a test platform, and a first slide way and a second slide way which are arranged in parallel and have the adjustable spacing distance are arranged on the test platform; a first tire base and a second tire base are arranged on the first slide way, and a third tire base and a fourth tire base are arranged on the second slide way, wherein the upper end of the first tire base, the upper end of the second tire base, the upper end of the third tire base and the upper end of the fourth tire base are located on the same plane as the upper surface of the test platform and all electrically connected with a signal acquisition instrument; and the signal acquisition instrument is externally connected with a computer terminal. The analysis platform is low in cost, good in operability and universality and capable of being used for testing the ride comfort and the handling stability of the vehicle. The invention further discloses a decomposition analysis method for the whole vehicle performance indexes of the commercial vehicle. Themethod is simple, feasible and capable of reducing the cost and test workload of whole vehicle performance analysis.

Description

technical field [0001] The invention relates to the field of vehicle dynamic performance analysis, in particular to a decomposition analysis platform and a decomposition analysis method for the performance index of a commercial vehicle. Background technique [0002] With the rapid development of my country's commercial vehicle industry, many domestic auto industries have begun two-way cooperation with world powers in the auto industry, and independently developed a variety of new commercial vehicle models under the leadership of foreign advanced technology and the background of independent innovation and research and development technology . The vehicle performance of a commercial vehicle mainly includes handling stability and smoothness, among which handling stability means that the vehicle can follow the driver's instructions through the steering system and the steering wheel given the steering wheel under the condition that the cab is not overly tense and fatigued.

Problems solved by technology

However, the performance testing and evaluation system of domestic R&D models still has the defects of high cost, poor universality and long test cycle. It mainly depends on the experience of the testers themselves, and at the same time, it is easy to cause different testers due to their own subjective ideas, so that some parameters are not considered and affect the analysis results differently, affecting the evaluation of the final vehicle performance
