A motorcycle shock absorber assembly performance detection system and control method

Abstract

The invention discloses a motorcycle damper assembling performance detection system which consists of a clamping / releasing button, a test button, a displacement sensor, a force sensor, a first signal regulating circuit, a first filter circuit, a USB-4711A multifunctional module, a computer, a second signal regulating circuit, an electromagnetic switching valve, a pressure reducing valve, a clamping cylinder, a second filter circuit, a proportion amplifier, an electro-hydraulic proportional direction valve, a working cylinder and a hydraulic source. The system of invention is simple to operate and convenient to install. With high automation, the work intensity of the test men can be greatly reduced. The system can also automatically generate test data and curves so that the assembling performance evaluation can be grounded. In addition, the system can position the physical position with poorly-assembled damper, changing the test manner that relies on the feelings of the work men. The invention further discloses a control method for the motorcycle damper assembling performance detection system.

Description

technical field [0001] The invention belongs to the technical field of product performance testing and test control, and relates to a motorcycle shock absorber assembly performance testing system and a control method, more specifically, to a hydraulically driven shock absorber realized by combining a computer with a multifunctional data acquisition module. A motorcycle shock absorber assembly performance testing system and control method. Background technique [0002] As a key component of motorcycle safety and performance, the shock absorber will be tested for a series of performance before the shock absorber product leaves the factory or the whole vehicle is assembled, one of which is the assembly performance. The current method is to manually grasp the piston rod of the shock absorber and press it down quickly, which is similar to the action of inflating a tire. It depends on the human hand to detect whether there is "" in one or some parts during the relative movement be...

AI Technical Summary

Problems solved by technology

This method is fast and simple, but there are the following problems: 1. When the batch of shock absorbers is large, it is very laborious to rely on human inspection, especially for shock absorbers with large loads; 2. There are empirical differences in human subjective judgments , Different people may make different judgments on the same shock absorber, either because of a sense of responsibility, or because they have different judgments on "astringent", and there is no visual evidence; 3. Even if a certain shock absorber is felt There are assembly quality problems in the device. In order to find the location of the problem, it may take multiple inspections and feelings, which is time-consuming and laborious.

[0003] Small-scale shock absorber manufacturers with low product performance requirements can barely maintain the quality of shock absorbers by using this method. For enterprises that produce in large quantities and have high product performance requirements, if they adopt this method, they will definitely not be able to meet high-end requirements. Requirements for shock absorbing products

Lack of testing equipment and means or lack of attention to this performance testing will directly affect other subsequent performance testing work. It is possible that subsequent performance testing is aimed at products that are not well assembled but are considered qualified, which will affect the judgment of subsequent performance testing results
