The test unit, or底盘 measurement device, plays a primary function in detecting the output power, torque, and speed of the driven wheel in an automobile. This helps engineering professionals understand the car's dynamical performance.
Additionally, it is utilized in load testing to diagnose potential issues arising from operating under specific loads. The test unit also includes features such as flywheel system, which measures acceleration and skid resistance characteristics.
Advanced test units incorporate features like flywheel system, measuring acceleration and skid resistance characteristics. These enhancements have been supported by advancements in electronic computer technology and specialized software, enabling the development of sophisticated test units.
