Heavy-duty vehicle frame road simulation test device

Abstract

The invention discloses a heavy-duty vehicle frame road simulation test device, comprising a front end fixing mechanism for fixing the front end of a vehicle frame assembly, a gantry for fixing the rear end of the vehicle frame assembly, and servo loading mechanisms performing vertical load loading in a way of being corresponding to six wheels of the vehicle frame assembly. The front end fixing mechanism comprises a horizontal fixed beam, and four vertical connecting rods arranged in a rectangle and a grounding connecting rod are disposed at the lower part of the horizontal fixed beam; the gantry comprises two vertical columns disposed at an interval on left and right sides, a crossbeam, and a connecting seat, the lower ends of the vertical columns are fixed to the floor, the connecting seat is disposed on the crossbeam, and is used for connecting a traction seat at the rear end of the vehicle frame assembly; each servo loading mechanism comprises a servo cylinder and a loading seat, the lower end of the servo cylinder is hinged to the floor, the upper end of the servo cylinder is hinged to the lower end of the loading seat, and the upper end of the loading seat is fixed on the vehicle frame assembly. The device is used for simulating force borne by the vehicle frame during a whole vehicle road test, evaluating and verifying endurance of the vehicle frame, and providing a basis for design of parts in development of a whole vehicle.

Description

technical field [0001] The invention belongs to the technical field of automobile industry engineering, and particularly relates to a vehicle frame road simulation test device, which is mainly used for simulating the force of the vehicle frame during the vehicle road test. Or verify the durability of the frame, and apply it to the verification of vehicle development parts. Background technique [0002] In the component verification stage of vehicle development, the frame, as an important component for the lightweight of heavy-duty vehicles, needs to be verified in a timely and effective manner for its durability. Traditional proving grounds have a long road test cycle and high cost, and changes in drivers and environments will also bring about test differences. In addition, there are often no complete vehicles in the component development stage, and their applicability is very limited. Therefore, bench tests are generally selected. [0003] Bench tests are divided into equa...

Problems solved by technology

However, reasonable and accurate test parameters are often difficult to obtain, so indoor bench road simulation tests have become a trend in durability verification

The road simulation test can efficiently and stably reproduce the loads on the vehicle or parts on the road indoors, but it has high requirements for the hardware equipment of the laboratory, the design of the test bench and the technical reserves of the test personnel.
