Reliability test platform for frame and traction transmission system of bogie of bullet train

Abstract

The invention discloses a reliability test platform for a frame and a traction transmission system of a bogie of a bullet train. The platform comprises a mechanical assembly part, a test platform base and a hydraulic pump station, wherein the test platform base consists of a concrete base of a rectangular pit, and a No.1 counterforce seat base platform, a No.2 counterforce seat base platform, a large-range adjustable platform, a base pit platform, a driving device base platform and a No.3 counterforce seat base platform which are poured in the concrete base and are positioned in the same horizontal plane; the mechanism assembly part comprises loading devices, an excitation system assembly and a semi-vehicle quality simulation device; the loading devices are fixed on the driving device base platform and the large-range adjustable platform; the excitation system assembly is provided with four vertical actuators and two horizontal excitation assemblies; the bottom ends of the four vertical actuators are fixedly connected with the base pit platform; one end of one horizontal excitation assembly and one end of the other horizontal excitation assembly are fixedly connected with the large-range adjustable platform and the No.3 counterforce seat base platform; and the bottom end of the semi-vehicle quality simulation device is fixed on the test platform base.

Description

Technical field [0001] The present invention relates to a test device, and more specifically, the present invention relates to a high-speed train bogie frame and a traction drive system reliability test bench that simulates the vibration environment of the high-speed train bogie when the real line travels. Background technique [0002] On April 18, 2007, my country successfully implemented the sixth national railway speed adjustment map. The Harmony CRH series EMUs appeared on the Chinese railways for the first time, achieving 250Km / h high-speed operation on existing lines, thus revealing The prelude to the development of high-speed railways in my country The maximum speed of the currently operating EMUs has reached 350km / h, but with the increase in speed, the operating conditions of the components of the high-speed train bogies have become worse, and the safety and reliability of key components in operation have become increasingly prominent . Therefore, higher requirements are...
