Construction and Design

Cam Analysis Machine FortiTestX 24 is constructed as a rigid benchtop strength of materials lab equipment unit mounted on a solid base. A three-phase asynchronous motor with frequency converter drives the camshaft via a coupling. Four interchangeable cam plates, tangent, convex, concave, and unsymmetrical, mount directly onto the camshaft. The tappet assembly sits above the cam and accepts either a flat tappet or roller tappet tracer. A spring and mass system is attached to the tappet to simulate the valve. Three interchangeable restoring springs of different rigidities and up to five additional 200 g weights attachable to the 530 g tappet allow independent variation of spring rate and moving mass. A mechanical drum plotter connected via synchronous belt drive and speed sensor records the actual lift curve in real time. The open frame design of this cam analysis machine ensures the complete cam and follower movement is visible during all experiments. All construction and materials conform to ISO 9001:2015 quality standards and meet CE marking requirements.

Software, FX-24 (Optional)

Customised software designed in the National Instruments LabVIEW environment for data logging and results processing. Compatible with any Windows-based operating system. The software is optional and selected independently of the base unit.

Frequently Asked Questions

Q1: How many cam types are included with the Cam Analysis Machine FortiTestX 24?
Four interchangeable cam plates are supplied: tangent cam, convex cam, concave cam, and unsymmetrical cam. All cams share a lift range of 15 to 25 mm and an opening angle of 140 degrees.

Q2: How is valve wobble demonstrated on the FortiTestX 24?
Valve wobble is demonstrated by independently adjusting three parameters: spring rate (via three interchangeable restoring springs), moving mass (via up to five additional 200 g weights on the tappet), and motor speed (0 to 1000 RPM via frequency converter). The interaction of these variables produces the valve wobble phenomenon at defined limit speeds.

Q3: How are lift curves recorded in the FortiTestX 24? A mechanical drum plotter connected via a synchronous belt drive with speed sensor records the actual lift curve of the cam and follower during operation. The plotter runs in synchronisation with the camshaft to produce an accurate lift versus angle trace.

Q4: What tracer types are available for the FortiTestX 24?
Two tracer types are provided: a flat tappet (93 g) and a roller tappet (20 g). Both are interchangeable and used with all four cam plate types to investigate the effect of tracer geometry on the lift curve and dynamic behaviour.

Q5: Is the stroboscope included as standard with the FortiTestX 24?
No. The stroboscope is an optional accessory available separately. It provides a detailed visual view of the cam and follower movement and lift during high-speed operation and is not part of the standard scope of delivery.
