Integrated test system and technology for falling-object protective structure and roll-over protective structure

Abstract

The invention discloses an integrated test system and technology for a falling-object protective structure and a roll-over protective structure. The integrated test system for the falling-object protective structure and the roll-over protective structure comprises an ROPS test system, an FOPS test system and a test piece clamping system, wherein the ROPS test system and the FOPS test system are arranged on the same horizontal plane and share a fixed type base workbench and the test piece clamping system. The FOPS test system is located on two parallel guide rails and can move back and forth along the parallel guide rails. According to the integrated test system for the falling-object protective structure and the roll-over protective structure, the ROPS test system and the FOPS test system are built on the same foundation and share a test piece multi-station clamping rotatable workbench and the fixed type base workbench, the FOPS test system moves to a test working position along the two traveling guide rails embedded in the foundation, and therefore an ROPS test and an FOPS test are integrated; in addition, the requirement for the ROPS performance test and the FOPS performance test of an engineering vehicle and a tractor is met.

Description

[0001] technical field [0002] The invention relates to a comprehensive test system for the driver's falling object protective structure (FOPS) and rollover protective structure (ROPS) for tractors and construction machinery, especially a system that can simultaneously meet the requirements of the driver's protective falling object protective structure (FOPS) and rollover protective structure (ROPS). Protective Structure (ROPS) Integrated Test System. Background technique [0003] At present, there are not many test equipments for driver safety protection devices developed in China. It is known that Jilin University, National Construction Machinery Quality Supervision and Inspection Center, and Luoyang Tractor Research Institute have similar test equipment and have carried out performance research on ROPS and FOPS accordingly, but these The equipment is a single-function and independent test system, or only has the rollover protective structure test equipment, or only has t...

Problems solved by technology

[0003] At present, there are not many test equipments for driver safety protection devices developed in China. It is known that Jilin University, National Construction Machinery Quality Supervision and Inspection Center, and Luoyang Tractor Research Institute have similar test equipment and have carried out performance research on ROPS and FOPS accordingly, but these The equipment is a single-function and independent test system, or only has the rollover protective structure test equipment, or only has the falling object protective structure test equipment, and the test capability is only satisfied with the construction machinery vehicle test, or only with the tractor test.

Since it is necessary to carry out loading tests in different directions such as horizontal and lateral, longitudinal and vertical directions, the specimen is required to be repositioned and clamped in different directions for many times, so the current specimen installation is cumbersome, the test procedure is relatively complicated, and the test The labor intensity of personnel is high, and the test takes a long time

At the same time, for the release of the impact test load of the FOPS test system, there are issues of safety and stability
