This equipment is mainly used for testing electric motorcycles and unicycles. It mainly uses servo motors to drive the rollers to rotate and provide load force to simulate road conditions. It can perform tests such as "maximum speed test", "road driving test", "acceleration performance test", "chassis dynamometer driving test", "constant speed climbing test", "constant slope climbing test", "100 km acceleration test", "maximum speed test", "continuation mileage test", and "100 km power consumption test" on electric motorcycles and unicycles. The vehicle is fixed on the fixture, and the equipment supplies power to the vehicle's motor. The start-up of the vehicle is set to rotate, and during operation, the load motor provides a programmable load torque to the wheels. The load torque, speed, voltage, and current of the vehicle during operation are detected, and the load power and input power of the power supply are calculated and plotted on a curve. All test data are recorded and support the generation of reports and export.
Test content description:
1. High-speed test of the unicycle, with the vehicle speed ranging from 130 to 150 km/h.
2. The unicycle can be fixed (currently by clamping the pedal).
3. There is adjustable damping to control the driving resistance. At high speed, it should remain stable without swaying.
4. It can be equipped with weights, and a person can stand and ride for testing.
5. It can walk actively or passively.
6. It can display speed, torque, power, current, voltage, and mileage (no DC power supply is required).
7. Test acceleration performance, climbing ability, maximum speed, minimum stable speed, input and output power, and fuel consumption (mileage).

Load simulation:
Laboratory-level replication of real road conditions. The equipment uses high-precision servo motors to drive the rollers (torque accuracy ±0.5N·m, speed accuracy ±1rpm), and simulates the resistance under different road conditions through "programmable load torque settings", covering the full range of scenarios from "light-load commuting" to "heavy-load climbing" for electric motorcycles and unicycles:
1.Adjustable load torque
The load motor provides programmable torque from 0 to 500N·m (electric motorcycle mode: 100 to 500N·m; unicycle mode: 0 to 100N·m), supporting scene settings such as "flat road resistance (50N·m)", "slope resistance (200N·m)", and "low resistance on slippery road (30N·m)";
The torque output curve can be customized (sine wave/square wave/random wave) to simulate dynamic resistance changes such as "continuous bumps" and "braking shock" (traditional road tests cannot control resistance fluctuations, with data deviation > 25%).
2.Roller speed control
The roller speed range is 0 to 120km/h (electric motorcycle) / 0 to 30km/h (unicycle), with an accuracy of ±1rpm, capable of simulating scenarios such as "city speed limit (50km/h)", "high-speed cruising (80km/h)", and "unicycle regular commuting (15km/h)";
Supports "acceleration/deceleration slope" settings (e.g., 0 to 50km/h acceleration time of 3 seconds), accurately reproducing instantaneous actions such as "starting from a red light" and "overtaking acceleration" (traditional equipment only supports constant speed testing).
