Problems solved by technology

[0003] For the acquisition of dynamic load, it mainly depends on modern testing technology. The research in this field is relatively mature at home and abroad, which provides sufficient conditions for the load test of wheel loader. This point is difficult to realize, and there must be false signals generated by various shocks and vibrations during the testing process

Embodiment

[0024] Example: such as figure 1 As shown, the wheel loader drive train load signal test and analysis process is carried out according to the following steps:

[0025] 1. Test the load signal of the wheel loader: according to the output torque of the engine, the torque output from the gearbox to the front drive axle, the torque output from the gearbox to the rear drive axle, the speed of the intermediate shaft of the loader, the forward gear, the reverse gear, the boom Cylinder large chamber pressure, boom cylinder small chamber pressure, boom cylinder displacement, a total of 9 test items determine the 1-9 channels of the test, and the load signal test of the wheel loader drive train is carried out as follows:

[0026] (1) Select the test prototype and determine the test conditions; select the ZL50 wheel loader, and require good working performance; prepare raw soil, stonework, and loose soil as a typical loading and unloading yard, and require sufficient materials; determine...

Abstract

The invention discloses a transmission system load signal testing, analyzing and processing method of a wheel-type loader; the transmission system load signal testing of the wheel-type loader is completed by a transmission system load signal testing module; a signal acquisition device and a recorder which are mutually connected form the transmission system load signal testing module; load signal analysis and processing are completed by a load signal analyzing and processing module, and the load signal analyzing and processing module analyzes and processes the load signal recorded by the recorder; the method solves the problems of transmission system load on-line actual measurement and load testing signal processing of the wheel-type loader, reduces the interference of pseudo-signals with load spectrum generation as possible, realizes the truth of the transmission system load spectrum, uses the transmission system load spectrum in the virtual test of the power performance optimization design of the wheel-type loader so that the precision is close to the real working environment of the loader, greatly shortens the performance testing time of the wheel-type loader, and improves the optimization design precision.

Description

technical field [0001] The invention relates to the field of optimal design of engineering vehicle power systems, in particular to a method for testing, analyzing and processing load signals of a drive train of a wheel loader. Background technique [0002] As a typical equipment of engineering machinery, wheel loader plays an important role in the field of engineering construction, and its performance directly affects the efficiency and quality of engineering. With the overall progress of modern equipment design technology, the performance of wheel loaders has been significantly improved, but there are performance gaps in the overall quality of the product in terms of power, economy, and reliability. The main reason is that in the process of product design and performance analysis, the traditional static strength design method is still stuck, and the dynamic load is not considered sufficiently. Therefore, in the design process, the process of dynamic load should be consider...
