A walking vibration test method of an excavator

Abstract

The invention provides a walking vibration testing method of an excavator, which belongs to the technical field of excavators. It solves the deficiency that the existing excavator walking test requires excavator operators to operate. The walking vibration test method of the excavator, wherein the walking vibration test device includes an excavator, a vibration belt, a remote control device, a controller, a display and a wireless receiving device, the controller is connected to the wireless receiving device and the display through a bus, and the controller is electrically connected to the wireless receiving device and the display. The joint proportional solenoid valve and vibration detector includes the following test steps: Step 1: Control the remote control device to send a command signal, the wireless receiving device receives the command signal sent by the control device, and transmits the command signal to the controller through the bus; Step 2: The controller The received command signal is identified, and a corresponding algorithm is performed according to the command signal to calculate the driving current signal that 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 to an excavator walking test method. Background technique [0002] According to the national mandatory inspection requirements, the excavator needs to be tested, and the excavator should be tested for walking vibration during the excavator test. 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 anti-vibration. [0003] The currently used test method is to drive the excavator on the vibrating runway, use the maximum throttle and use the high-speed walking mode, and do reciprocating walking on the vibrating runway. There are many uneven and certain height obstacles on the runway to make t...

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
