Abstract

The invention discloses an architecture locating device for a bogie parameter test bench. The architecture locating device for the bogie parameter test bench is used for solving the problem that the three-direction locating cannot be achieved. The architecture locating device comprises an anti-thrust beam assembly I, an anti-thrust beam assembly II, a transverse counterforce supporting seat I, a transverse counterforce supporting seat II, a transverse counterforce supporting seat III, a transverse counterforce supporting seat IV, a longitudinal-transverse constraint framework, a vertical locating mechanism assembly I and a vertical locating mechanism assembly II, wherein the two ends of the anti-thrust beam assemblies (I and II) are fixedly arranged at the lower ends of four parameter test bench vertical columns of the bogie parameter test bench, the transverse counterforce supporting seats (I, II, III and IV) are uniformly distributed between the two ends of the anti-thrust beam assemblies (I and II), the bottom ends of the transverse counterforce supporting seats (I, II, III and IV) are connected with a foundation, the longitudinal-transverse constraint framework is arranged at the center of the bogie parameter test bench and is connected with the bogie parameter test bench through bolts, and the bottom ends of the vertical locating mechanism assemblies (I and II) are connected with a cast iron platform through bolts.

Description

Technical field [0001] The invention relates to a bogie parameter test and detection equipment. Specifically, the invention relates to a bogie parameter test bench frame positioning device. Background technique [0002] When determining bogie parameters, the positioning of the bogie frame is a very important part. If the frame is not positioned in a certain direction, the stiffness parameter in that direction cannot be measured; if the frame is not positioned correctly in a certain direction, it will cause measurement The accuracy drops and measurement errors occur. At present, the positioning method of the frame can be divided into two types, namely, wheelset fixing or frame fixing. Using the wheel-set fixing method, force is applied to the frame during the test to cause relative displacement between the frame and the bogie. However, this fixing method cannot distinguish the stiffness parameters of the primary and secondary suspension, and can only measure the comprehensive sti...
