3. SSCD400-1800-4000 Vehicle Axle Electric Dynamometer Test Bench System Core Advantages

1) Dual dynamometers work together to cover all working conditions: Equipped with dual SSCD400-1800-4000 dynamometers for drive and load, each unit has a rated power of 400kW, torque of 2119Nm, rated speed of 1800rpm, and maximum speed of 4000rpm. It can accurately simulate the drive and load characteristics of Vehicle axles under complex working conditions such as climbing, high-speed driving, and heavy-load traction, comprehensively covering the full working condition performance testing of axles of heavy commercial vehicles and special engineering vehicles, and is suitable for response verification of torque impact and sudden speed changes under extreme road conditions.
 

2) A high-precision measurement system ensures high data reliability: It adopts an HBM ultra-high precision torque flange with an accuracy of 0.1% FS, a speed resolution of 0.05 rpm, and a dynamic response of ≤0.8 ms; paired with a Seelong high-end power analyzer with a basic accuracy of ≤0.02%, combined with a multi-dimensional high-precision data acquisition system (temperature accuracy ±0.3℃, vibration frequency coverage 5Hz-20kHz), it achieves millisecond-level accurate acquisition and in-depth analysis of key parameters such as torque, power, temperature, vibration, and pressure.
 

3) The system is stable, reliable, and highly compatible: The Siemens variable frequency inverter system adopts high-performance vector control technology, has four layers of safety protection, is compatible with a wide voltage input of 380V-480V, and has industry-leading operational stability; the battery simulator supports a wide voltage output of 36-1500V and a high current of ≥1200A, is compatible with 10 types of battery models, and has an energy feedback efficiency of ≥92%, which not only meets the power matching needs of axles of different power levels, but also achieves significant energy saving and consumption reduction.
 

4) Optimized structural design, balancing safety and stability: The adjustable mounting bracket has a center height adjustable from 300-700mm, increasing the load-bearing capacity to ≥1500kg, and the flatness error of the mounting surface is ≤0.015mm/m; The HT400 high-strength cast iron plate is combined with a honeycomb reinforced shock-absorbing structure to effectively offset the vibration generated by high-speed and high-torque testing; The fully enclosed explosion-proof protective cover has built-in high-efficiency sound-absorbing material, which works in conjunction with the system to achieve dual safety protection, taking into account the needs of safety, noise reduction and heat dissipation.

5) Intelligent measurement and control upgrade, efficient and convenient operation: The XLP-1000 measurement and control system is equipped with an I7 industrial computer ( 32G memory + 1T SSD), and dedicated software supports multi-condition preset, real-time data visualization, and custom report generation; the lubrication station has intelligent flow regulation, precise oil temperature control and multi-level early warning functions, and the three-loop design of the chiller is precisely adapted to the cooling needs of multiple modules, which greatly reduces the cost of manual intervention and improves testing efficiency.
