Product Introduction
All parts of the vehicle road simulation test system equipment are made of high-quality brand components at home and abroad. The product performance is excellent, and it covers a wide range of tests. It is a vehicle-level test equipment with good comprehensive performance. The equipment can be used for traditional fuel vehicles, pure electric vehicles, hybrid vehicles and other vehicle tests.
Product Capability
The test load simulates the actual or artificial test road spectrum through a set of hydraulic servo actuators in the manner of tire coupling, and conducts endurance fatigue and vibration tests on the vehicle and its assemblies and subsystems. At the same time, the motion situation of the user's road or proving ground is reproduced on the test bench by using the remote parameter simulation technology.
By using this test system, it can be equivalent to replace the vehicle on the test track to test and evaluate the durability performance, while ensuring the reliability of the vehicle, it can shorten the development cycle of the model.
Main Test Content
◆ Component model optimization
◆ Endurance fatigue assessment of body and body accessories
◆ Chassis structure endurance fatigue test
◆ Vehicle suspension dynamic characteristic test
◆ Driving comfort test
◆ Vehicle Abnormal Noise Test
◆ Vehicle or component vibration and noise assessment
◆ Production off-line quality control
In general, this equipment is mainly used to improve the ability to evaluate the early structural durability, abnormal noise, driving comfort, etc. It can effectively shorten the R&D cycle and improve the R&D quality of the whole vehicle.
Product Features
◆ High precision: High precision of road spectrum reproduction, RMS error of road spectrum reproduction is <5%, peak-to-peak error is <5%, which can restore the actual road conditions most realistically; The actuator valve block is equipped with a flow selector, which can automatically switch between large and small flow; the large flow is used in the durability test, and the small flow is used in the NVH abnormal sound detection test to ensure the test accuracy.
◆ High response frequency: The frequency band of road spectrum reproduction is up to 100Hz, the maximum speed of the actuator is up to 4m/s, and the response frequency performance is excellent among the products of the same category.
◆ High reliability: The actuator adopts hydrostatic bearing structure and special coating technology to ensure the reliability of the test process.
◆ Hard core technology: The oil cylinder, oil source system, controller, control software, road simulation and reproduction algorithm are all independently developed.
◆ Low noise: The servo oil source system adopts a quiet design, which can achieve the laboratory-level mute effect, and the noise is less than 70dB.
◆ Low energy consumption: The hydraulic oil source adopts the energy-saving design scheme, which can save the user's energy consumption to the greatest extent. Under the condition of low power output, it can adapt to the variable output and reduce the energy consumption of the system.
◆ Digitization: The software adopts the platform development method, which has powerful functions and can complete various flexible testing tasks.
Our Advantage
