Problems solved by technology
The front half of the test vehicle frame is cut from the real vehicle frame. Due to the cost reduction, the real vehicle frame is generally a single-layer longitudinal beam, which will cause problems of insufficient rigidity and strength. It is easy to crack, which not only affects the test efficiency, but also affects the iteration accuracy due to insufficient rigidity

Abstract
The invention discloses a commercial vehicle cab road simulation vibration endurance test vehicle frame, which comprises two longitudinal beams arranged in the longitudinal direction, a first cross beam, a second cross beam and a third cross beam, wherein the first cross beam, the second cross beam and the third cross beam are sequentially arranged between the two longitudinal beams from front toback in the transverse direction. The height of the longitudinal beam is equal to that of a frame longitudinal beam of a commercial vehicle, and the longitudinal beam is a double-layer longitudinal beam. According to the commercial vehicle cab road simulation vibration endurance test vehicle frame, the longitudinal beams are of a double-layer beam structure, so that the strength of the longitudinal beams is improved, and the cracking risk of the longitudinal beams in the test process is avoided; and a front cross beam, a middle cross beam and a rear cross beam are connected with the double-layer longitudinal beams, and the requirements for rigidity, strength and iteration precision in the test process are met through a simple frame structure, and reliability and test efficiency are greatlyimproved.
Description
technical field [0001] The invention relates to the technical field of commercial vehicles, in particular to a vehicle frame for road simulation vibration durability tests of cabs of commercial vehicles. Background technique [0002] The commercial vehicle cab road simulation vibration durability test needs to assemble the commercial vehicle cab on the test frame (half frame) through the suspension system, and the 7 actuators are connected to the test frame (half frame) through the L plate fixture. Connected, the road simulation vibration durability test of the cab is carried out through the road spectrum drive actuator. [0003] The test vehicle frame adopted in the prior art scheme usually adopts the real vehicle frame to cut the front half, and the front half vehicle frame of the real vehicle frame is a single-layer longitudinal beam. The front half of the test vehicle frame is cut from the real vehicle frame. Due to the cost reduction, the real vehicle frame is generall...
