Our Products
Investmech supplies a range of products, tailor made to satisfy a client specific need. Contact us if you need a specific product and we will be pleased to submit you a proposal for the development thereof.
Software
Investmech has developed the following software packages that are used in world class test laboratories:
- This C++ based program calculates the fatigue from measured or simulated stresses.
- This PC Matlab based tool will be used to integrate measured or simulated signals.
- This PC Matlab based algorithm is used to generate drive or other signals.
- This is a signal analysis toolbox that calculates PSD’s, waterfall displays, Campbell diagrams, order tracking, and other NVH applicable responses.
- Testing toolboxes that include Nocker and Shocker. Shocker is a toolbox that was developed for the characterization of shock absorbers.
- This is software that characterizes elastic components for different stiffness and damping characteristics.
- This software determines the crack growth properties of a material, as well as the fracture toughness automatically.
- This is PC Matlab based algorithm to assist Finite Element Specialists to identify input forces for measured responses. Investmech has unique experience in this field.
- Several servo-hydraulic test control packages for the automatic control of towing device tests, etc.
Hardware
Due to Investmech’s focus in the durability test field, the company has developed servo-hydraulic actuators, servo-controllers, signal conditioners, and has agency contracts with the UK Star Hydraulics company for the supply of test equipment. The following products are distributed by Investmech:
- Servo-hydraulic actuator.
- Accelerometer Amplifier.
- Analogue servo-hydraulic controller.
- Digital PID servo-controller.
- Fatigue rated load-cells.
- Star Hydraulics servo-valves.
- Start-stop valves for hydraulic test equipment.
- Hydropuls testing machine.
- Test control software.
- Complete test systems.
- Test jigging
- Hydraulic cylinders
- Hydraulic start-stop valves
Four-poster test rig
Investmech supplies multi-actuator test rigs ranging in actuator size from 25 kN to 100 kN in size. Applying ARX models, drive signals are calculated that result in accurate reconstruction of field recorded responses
Servo-hydraulic actuators
Investmech supplies a wide range of servo-hydraulic actuators with application specific hydrostatic or hydrodynamic bearings. Our actuators are used in single and multi-axial durability and characterisation tests.
Dynamic vibration absorbers
Investmech designs and manufactures dynamic absorbers (damped and undamped, depending on application) for vibration control due to resonance. Investmech successfully applied this technology to control vibration of linkages, floors and roof elements. The dynamic vibration absorber is fine tuned in the Investmech test laboratory to ensure efficient control of vibration at resonance.
