Uniaxial straddle type bogie dynamic parameter and traction dynamic performance test bench

Abstract

The invention relates to a uniaxial straddle type bogie dynamic parameter and traction dynamic performance test bench, which comprises a bogie guidance and stabilization system test device, a walkingwheel traction and posture driving system device, a cloud rail vehicle constraint truss and two-degree-of-freedom moving vehicle body device and a test load weight frame device which are mounted on atest area iron floor 3; the test bench meets the need to test the main dynamic parameters for the uniaxial straddle type monorail bogie in the operating state, performs dynamic and static testing on stiffness parameters of the single uniaxial straddle type monorail bogie, and truly simulates five forms of movement of lateral moving, vertical moving, yawing, rolling and nodding of the uniaxial straddle type monorail vehicle by applying the lateral force to the four guide wheels, the lateral force to the two stabilizing wheels, the lateral force and the vertical force to the travelling wheel ofthe uniaxial straddle type monorail vehicle.

Description

technical field [0001] The invention relates to a single-axle straddle type monorail vehicle performance test bench, in particular to a single-axle straddle type bogie dynamic parameter and traction power test bench. Background technique [0002] With the rapid development of social economy and the advancement of urbanization, urban traffic is facing enormous pressure, especially in medium and large cities, the existing traffic system has gradually become one of the bottlenecks of sustainable economic development, the development of urban The rail transit system is an effective solution. Monorail transportation, like light rail transportation, adapts to the needs of urban traffic transportation between large-capacity subways and low-capacity public electricity and cars. And because it has different characteristics from other rail transits, such as small footprint, ability to adapt to complex terrain conditions, good environmental protection effect, short construction period...
