Tractor protective device testing platform and testing method thereof

Abstract

The invention provides a tractor protective device testing platform and a testing method thereof. The testing platform comprises a mechanical structure system which comprises a gantry framework assembly, a cast iron platform assembly and a tested object tooling assembly; a hydraulic system which comprises a hydraulic pressure station, a crushing oil cylinder group of an integrated force displacement senor, a rotating oil cylinder group of the integrated force displacement sensor and a hydraulic pipeline and an electrical control system which comprises a control cabinet and the like; the gantryframework assembly and the tested object tooling assembly are installed on the cast iron platform assembly which is fixed to a foundation A; the hydraulic pressure station and the crushing oil cylinder group of the integrated force displacement senor are installed on the gantry framework assembly, the rotating oil cylinder group of the integrated force displacement sensor is installed on the gantry framework assembly in a sliding mode, the hydraulic pipeline is connected with input ends and output ends of the hydraulic pressure station, the crushing oil cylinder group of the integrated forcedisplacement senor and the rotating oil cylinder group of the integrated force displacement sensor separately; the control cabinet is installed on the gantry framework assembly, and a computer is located outside the gantry framework assembly. The testing method is scientific and reasonable and high in practicability.

Description

technical field [0001] The invention belongs to the field of tractor test equipment, and relates to a tractor protective device test bench and a test method thereof. Background technique [0002] At present, there are mainly three types of static tests on tractor protective devices at home and abroad: longitudinal loading test, lateral loading test and crushing test. The purpose of the test is to verify the rigidity and strength of the tractor protective device, so as to minimize the possibility of injury to the driver due to a rollover accident during normal operation of the tractor. [0003] In June 2014, Chen Xiaoling from Nanjing Agricultural University published "Design and Research on the Strength Test Bench of Tractor Protective Devices" on CNKI, pointing out that the test bench is composed of two major devices, namely: horizontal loading device and crushing loading device. The horizontal loading device mainly consists of four parts: a vertical loading beam, a horizo...

AI Technical Summary

Problems solved by technology

When carrying out longitudinal loading test and lateral loading test, some need multiple hydraulic cylinders to complete the longitudinal and lateral loading, and some need to move the loading device or the test piece by driving multiple times during the test, the operation is complicat
