Soil bin testing device suitable for testing of running performances of wheel

Abstract

The invention discloses a soil bin testing device suitable for the testing of running performances of a wheel, and the device comprises a soil bin system, a single-wheel testing system, a plough loosening flattening system and a control system. The single-wheel testing system is disposed on the soil bin system and makes reciprocating motion in the length direction of the soil bin system. The plough loosening flattening system is disposed at the front part of the single-wheel testing system, and the control system is electrically connected with the soil bin system, the single-wheel testing system and the plough loosening flattening system. The device can achieve the simulation of different bearing conditions of the wheel, can control the speed and slippage rate, meets the requirements of the testing of the running performances of different types of wheels under different soil conditions, achieves the automatic control of a testing process, collects and storage the related running performance parameters in real time, can achieve the research of the impact on the trafficability from a running condition factor, a wheel related factor and a soil factor through an indoor test, and is advantageous in that the test conditions and environment factors can be controlled, the test repeatability is good and the test precision is high.

Description

technical field [0001] The invention relates to an automatic control test equipment integrating electric drive technology, air pressure loading technology and PLC control technology, in particular to a soil tank test device suitable for wheel driving performance testing. Background technique [0002] Vehicle ground mechanics is a subject that studies the interaction between the wheel and the ground. It studies the interaction mechanism between the running mechanism and the soil under different soil conditions and driving conditions by means of theory, simulation, and experiments. The trafficability, the structural optimization of the traveling mechanism, and the prediction and evaluation of the drivability of various road surfaces have important guiding significance. [0003] Vehicle ground mechanics is also a subject that pays equal attention to theory and experiment. The indoor soil tank test is an important means to study the interaction between the wheel and the soil. Co...

AI Technical Summary

Problems solved by technology

It can be seen that the soil tank test bench currently developed is mainly used in the fields of agricultural machinery and planetary exploration, and is not suitable for driving performance tests of different types of wheels under different soil conditions, wheel loading conditions, and driving conditions. development, this type of soil tank test equipment needs to be developed urgently
