VT-6 series Servo-vibration Controller
VT-6 series servo-vibration controller integrates the capacity of servo-valve control and vibration control together innovatively and powerfully. It features HVS series servo-hydraulic vibration testing system to be delivered with compact design, simpler connecting in loop control, easy in installation and operation.
Based on advanced digital control and PID algorithms, VT-6 composes of double loop controls, displacement and acceleration, at same time. This makes servo-hydraulic shaker under a stable, reliable and precise control, with better frequency response and wider usable range.
VT-6 is a PC independent controller, all operation of the vibration system is performed through the VT-6 software computed by on board DSP. Its hardware has considerable design in connecting with different types displacement sensor and accelerometers. VT-6 is fully compliant with all servo-hydraulic vibration systems from other vendors.
Features
- Integration of vibration control and servo valve control
- Dual loop control of displacement and acceleration
- Combination of digital control and PID control
- Dedicated connectors to different sensors
- Compliant with all servo-hydraulic vibration systems
- Full range of testing control software: sine, random, stock RSTD and Field Data Replication

4-post Road Simulator
4-post servo-hydraulic road simulator is rather useful to reproduce simulate road excitation on vehicle and its parts, to search performance characteristics, test reliability and durability. Most of vehicle parts need such tests including body in white, suspension, lights, A/C, seat, instrument meters and so on.
HVS-25.4 road simulator has considerable 4 posts design with multiple hydraulic actuators and dedicated wheel-pan, sophisticated time domain MIMO loop control. HVS-25.4 meet all testing standards of vehicle road simulation, design and type test, life test, end-of-line product quality test.
HVS road simulator could be extended to be 6-post, 8-post or more, for vehicles with more wheels or specified mission profile.
Features
- Servo-hydraulic 4-post simulation
- Compact design, less field room needed
- Typical 25 kN actuators with 200 mm stroke design
- Customized force from 10kN to 300kN
- Applications: Vehicle quality test, ride comfort, mission profile
