Problems solved by technology

[0005] However, the above-mentioned test scheme has the following deficiencies: 1. The test mode is too single, and can only test the V-shaped thrust rod tension-compression fatigue and the lateral force at the end of the V-force rod; the failure mode of the test is inconsistent with the failure mode of the real vehicle; 2. Models cannot simulate complex conditions

Abstract

The invention discloses a V-shaped thrust rod testbed. The testbed comprises a base, a head supporting seat, a transition connecting board, an actuation bracket, a lateral actuation device, two vertical actuation devices, a longitudinal actuation device and supporting devices, wherein the head supporting seat is fixed on the base and is suitable for the fixation of a head of a V-shaped thrust rod;the transition connecting board can be vertically movably arranged on the base and is suitable for the fixation of legs of the V-shaped thrust rod; the actuation bracket is fixed on the base; the lateral actuation device is connected to the side direction of the transition connecting board; two vertical actuation devices are connected to the upward side of the transition connecting board; the longitudinal actuation device is connected to the longitudinal direction of the transition connecting board; the longitudinal actuation device and the head supporting seat are positioned on the same sideof the transition connecting board; and the supporting devices are arranged on the base and are connected to the longitudinal direction of the transition connecting board. Based on the invention, thetransition connecting board is arranged, so that the installation form and the stress state of the V-shaped thrust rod can be similar to those of a real vehicle, and therefore, road spectrum playbackand test acceleration can be performed on the testbed.

Description

technical field [0001] The invention relates to the field of vehicle testing, in particular to a V-shaped thrust rod test stand. Background technique [0002] The commercial vehicle V-shaped thrust rod assembly is connected with the axle at one end, and connected with the cross beam of the frame at the double end, which bears lateral force and longitudinal force, and has relative displacement in the vertical direction, so that the ball head and the rubber joint are twisted. [0003] The V-shaped thrust rod is a key component of the suspension system. At present, there is no unified test method and standard for the V-shaped thrust rod assembly bench in China. It is of practical significance to discuss the test method and scheme of the V-shaped thrust rod assembly bench. [0004] In related technologies, the commonly used system of the test bench is the electro-hydraulic servo system. According to the force and motion analysis of the V-shaped thrust rod, the V-shaped thrust ro...
