The Design of Shield Tunnelling Machine Cutter Header's Cutting Performance Test Bed

In order to solve the problems of data access and low accuracy on the shield tunnelling machine construction site, a test bed that can simulate the shield tunnelling machine cutter head's cutting performance is designed. The test bed's box uses a fixed cutter head and a turning material bin. The whole configuration is designed to a welding framework. The cutter head is designed to a spoke form. The fixing angle and the distance between different cutters can be adjusted at random. The propelling and loading system of the test bed are controlled in an electro-hydraulic proportional control manner. It can be used to test the single factor and multiple factors that influence the cutter head's cutting performance.
