Flagship All-Round Intelligent Comprehensive Roller Test Bench, High-Precision Testing Equipment For Full-Working-Condition Vehicle Performance
This full-range compatible intelligent comprehensive roller test bench is a new-generation vehicle performance testing equipment integrating five core technologies: electric inertia simulation, four-quadrant motor loading, high-precision sensor acquisition, intelligent algorithm analysis and multi-system linkage control. It solves the common industry problems of traditional single-function roller benches, such as distorted working condition simulation, narrow vehicle compatibility, scattered testing items and insufficient data accuracy.
Description
The entire comprehensive roller test bench adopts a dual-core technical framework of electric inertia dynamic simulation and four-quadrant motor loading, which is fundamentally different from traditional mechanical inertia and simple roller equipment, greatly improving the authenticity of working condition simulation and the accuracy of test data. The main body of the equipment adopts high-precision dynamically balanced roller components, which are precisely machined and dynamically balanced calibrated to ensure no jitter or deviation during high-speed operation, providing a stable simulated driving road for vehicles.
The roller group is equipped with high-resolution encoders and tension sensors to collect core data such as speed, torque and braking force in real time. The measurement accuracy reaches ±0.1% full scale with minimal repeatability error, ensuring the reliability and consistency of test results. Equipped with a four-quadrant AC servo motor loading system, it supports four control modes: constant speed, constant torque, constant power and resistance simulation. It can accurately simulate rolling resistance, air resistance, ramp resistance and acceleration inertia during vehicle driving, truly restoring full-scenario working conditions such as urban congestion, high-speed driving, climbing and overtaking, and emergency braking.
Different from the limitation of fixed resistance simulation of traditional equipment, this system can dynamically adjust loading resistance according to different vehicle models, loads and speeds, adapting to personalized testing needs of various vehicles. Built with an intelligent electric inertia simulation algorithm, it can accurately reproduce vehicle driving inertia without mechanical flywheels, greatly simplifying equipment structure, reducing energy consumption and operation & maintenance costs. Meanwhile, it integrates a dynamic error compensation algorithm to automatically eliminate external interference such as ground vibration, ambient temperature changes and equipment wear, ensuring data stability during long-term continuous operation.
The entire test process realizes fully automatic unmanned operation. The whole process of vehicle parking, adaptive wheelbase adjustment, test start, data collection and report generation is automated without manual intervention, which greatly improves testing efficiency and avoids human operation errors.
