Overview

The Computerized Handheld Wheel Spin Test Rig is a precision system designed to evaluate frictional losses of vehicle wheel axles.
It enables torque, rotational speed, and inertia testing with full data acquisition through NI DAQ software and a handheld motorized test gun.

General Description

• Compact, lightweight rig for wheel spin and friction testing on vehicle axles.

• Operated using a brushless motor gun (3000 RPM, geared 100:1 to 30 RPM output).

• Rotation control via trigger switch — supports both clockwise and counterclockwise operation.

• Speed variation by integrated snap action switches on the gun.

• Real-time speed and torque displayed on the TWIX2 indicator.

Installation

1. Place the rig on a flat surface with sufficient rotation clearance.

2. Check for damage or loose components before power-up.

3. Connect 230 V AC single-phase power with proper earthing.

4. Turn ON main MCB, then MAINS ON switch.

5. Ensure all electrical panels are OFF before servicing.

Technical Specification

Key Components

Testing Capabilities

• Automatic Torque Test – Software-driven torque measurement sequence.

• Manual Torque Test – Operator-controlled torque/speed testing using gun control.

• Inertia Measurement Test – Calculates rotational inertia of wheel assembly.

• Bidirectional Testing – Clockwise and counterclockwise motion supported.

Software & DAQ System

Controlled by LabVIEW-based DAQ Software, offering:

• Automatic and manual test modes.

• Schedule creation and editing (pressure, speed, temperature, duration).

• Real-time data monitoring.

• Graphical and numerical test reports (Excel/PDF).

• Automated data saving at D:/exe/report/….

Test Workflow

1. Power ON mains, drive, and electronics.

2. Launch DAQ Control Software.

3. Create or select a Test Schedule.

4. Enter login details and mount gun on the wheel.

5. Start test — follow instructions in status bar.

6. View test report (raw or graphical).

Reports & Data

• Automatic Torque Report: Numerical & graphical (raw data in Excel).

• Inertia Report: Acceleration graphs, mapping charts, and data summary.

• Reports can be saved in PDF or Excel formats for traceability.

Manual Test Mode

• Two options: Auto Mode (speed set in software) or Manual Mode (gun-controlled).

• Used for calibration, maintenance, or quick performance checks.
