Semitrailer suspension system test method and terminal

Abstract

The invention discloses a semitrailer suspension system test method and terminal, and the method comprises the steps: controlling a main vehicle to drive tires at the left and right sides of a lightweight semitrailer to sequentially pass through equal-distance deceleration strip groups which are arranged at the left and right sides of a road and have the same number, and guaranteeing the same vibration times at the left and right sides of the semitrailer; due to the fact that the distance between tires of the semitrailer and tires of the main vehicle is long, when the main vehicle passes through the deceleration strip set and then turns towards the direction away from the deceleration strip, the semitrailer can pass through the deceleration strip, the main vehicle can avoid the deceleration strip in the driving process, loss of the main vehicle is reduced, and the tires on one side of the semitrailer can obtain vibration with enough strength through the deceleration strip. The semitrailer is parked on a measuring station after passing through all deceleration strip sets, distance parameters of a suspension system of the semitrailer are measured through laser, and vibration performance parameters and test results are obtained; therefore, the main vehicle and the semitrailer do not need to be separated in the measurement process, the parking angle of the semitrailer does not affect calculation of vibration performance parameters, and the detection efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of logistics equipment testing, in particular to a testing method and terminal for a suspension system of a semi-trailer. Background technique [0002] In recent years, with the rapid development of the country's economy, the logistics industry has gradually changed, especially the strict implementation of the country's anti-supermarket. Everyone hopes to be able to load more goods under the premise of meeting the regulations to improve transportation efficiency. Therefore, it is Someone proposed a lightweight semi-trailer. The lightweight semi-trailer is different from the traditional semi-trailer. First, high-strength aluminum alloy profiles are used for a large number of parts such as the beam and sub-beam, and the overall weight of the semi-trailer is greatly reduced through high-strength aluminum alloy profiles. , but its carrying capacity and load bearing capacity have not been reduced. [0003] At present, the...

Problems solved by technology

[0004] However, the welding structure and welding materials of ordinary semi-trailers are different from lightweight semi-trailers made of high-strength aluminum alloy profiles. The vibration force at each position is different, resulting in different deformations of parts at each position. Therefore, the method of testing vibration for ordinary semi-trailers is not applicable. Lightweight semi-trailer with high-strength aluminum alloy profiles; and the vibration road test of ordinary semi-trailer is not only time-consuming and laborious, but also due to the unreasonable distance of roadblocks and the unreasonable amplitude of roadblocks, the damage to the body of the semi-trailer and the main vehicle during the driving process is great. permanent
