Chassis Dynamometer VULCAN
Overview
Evolution of Design
HORIBA continues to accumulate substantial knowledge in designing and manufacturing high-quality chassis dynamometers for the automotive industry in compliance with existing and forthcoming emission standards. Continuous optimization and improvement of the tried-and-tested design have led to the latest generation of VULCAN dynamometers. While creating this new range of chassis dynamometers, the HORIBA team reexamined fundamental design elements that are crucial to the performande demanded by our users. The digital force and speed measurement designs are characterized by their high accuracy and repeatability. Automated quality checks and product diagnostics additionally contribute to the performance of the overall system.
To advance the quality of the measurement results, HORIBA has improved calibration and measurement accuracy as well as the roller dimensions, enabling it to comply with current and future vehicle demands. A standard calibration device using a two arm design for full force calibration through the zero point assures easy and reliable calibration.
Features
- Highly accurate force and speed measurement (force repeatability typ. ± 0.005 % f.s.)
- Extended speed range up to 270 km/h available
- Zero warm-up time
- Convenient packaging allows easy retro-fitting into existing sites and future upgrades
- Remote maintenance for advanced system diagnostics
- Unique, easy-to-use two arm design calibration tool for full force calibration through the zero point
- Wheelbase range extendable to up to 4,400 mm
- Increased system and measurement reliability thanks to routine and preventative maintenance programs and built-in quality checks
- Wide range of optional features available
Key Features of Latest Generation
Modular Design
The latest generation of HORIBA VULCAN Chassis Dynamometers is characterized by a robust, modular design that offers improved performance, as well as increased flexibility and serviceability. The system is comprised of three pre-assembled and aligned main modules, a design which significantly reduces installation and maintenance costs. Numerous built-in functions in the area of diagnostics, calibration, handling, and vehicle parameterization are standard. Different AC power and roller inertias enable testing on a wide range of vehicles and applications, while the base-independent pit decking design ensures simple adaptation to various pit dimensions. In addition, VULCAN is easily upgraded from 2WD to 4WD applications.
SPARC VEHICLE Controller
The VULCAN system is equipped with the HORIBA SPARC VEHICLE Controller, including standard interfaces for emission host systems such as HORIBA’s market leading VETS system. In addition, HORIBA has made a number of improvements to this controller, which now offers various new features.
Main improvements of SPARC VEHICLE Controller
- Road load simulation via polynomial and multipoint functions
- Excellent friction loss compensation
- Parasitic loss measurement with coast down, ramping method and constant speed method
- Multiple user levels
- Operation response time measurement
- Support for three additional, vehicle-independent airstream blower sets
- Possible extensions, such as augmented braking, operating hour counter, etc.
