Walking vibration test method for excavator

Abstract

The invention provides a walking vibration test method for an excavator, belongs to the technical field of excavators, and solves the problem that the walking test of an existing excavator needs an excavator operator. According to the walking vibration test method for the excavator, disclosed by the invention, a walking vibration test device comprises an excavator, a vibration band, a remote control device and wireless receiving equipment, wherein the wireless receiving equipment is connected with a controller and a display through buses, and the controller is electrically connected with a proportional solenoid valve and a vibration detector. The walking vibration test method comprises the following test steps: step 1, the remote control device is controlled to give out a command signal which is received by the wireless receiving equipment, and the command signal is transmitted to the controller through the buses; step 2, the controller distinguishes the received command signal, performs a corresponding algorithm according to the command signal, and calculates a drive current signal which needs to be output to the proportional solenoid valve.

Description

Technical field [0001] The invention belongs to the technical field of excavators, and relates to an excavator testing method, in particular a walking test method of an excavator. Background technique [0002] According to the national mandatory inspection requirements, the excavator needs to be tested. In the excavator test, the excavator must be tested for walking vibration. When doing the walking vibration test, the excavator operator operates the excavator in the cab, uses the maximum throttle and uses the high-speed walking mode, and reciprocates on the vibrating runway. The excavator generates a lot of vibration during this process. The excavator is tested for walking vibration resistance. [0003] The test method currently used is to drive the excavator on a vibrating runway by the operator of the test excavator, use the maximum throttle and use the high-speed walking mode, and walk back and forth on the vibrating runway. There are many uneven obstacles of a certain height...

AI Technical Summary

Problems solved by technology

[0005] In the existing excavator walking vibration detection, the vibration test time is relatively long, during the test process, it will cause great damage to the human body, and the excavator will generate more noise than normal work, which will cause great damage to the hearing of the excavator operator. ; The vibration frequency of the excavator varies in a large range, and the vibration intensity of the excavator is very large. During the period of resonance with the human body, it will cause great damage to the human skeleton and other physiological systems; Vibration will cause a large change in the opening of the pilot valve, which will have an impact on the hydraulic system of the excavator

There is no detection of the vibration intensity, and the shock resistance test of the excavator can only be guaranteed by extending the time
