Transmission. With timing belts, in 2 reduction stages. This type of belts combined with the use of lineal ball bearings, puts almost all the power at the Dyno shaft, allowing it to work at very low & high speeds with grater shock loads.
Frequencies & velocities. Frequencies from 0,1Hz up to 6Hz . With this frequencies, the shaft speed can go from 0,16”/sec (4mm/sec) to 37.4”/sec (950mm/sec).
Force sensing. Z type load cell.
Position & velocity sensing. Digital high precision encoder system.
Moving transformation system. Scotch yoke (describes a perfect sinusoidal function). The mechanism has a frictionless no backlash mechanic solution, really useful for short stroke. For the stroke change, the machine has a clamping mechanism with 4 options: 0.5”/ 1”/ 1.5”/ 2”. The software recognizes the new stroke automatically.
Data acquisition system of exclusive development, works combined with a YASKAWA AC Drive. The system is totally commanded by software.
Software. Developed in C++, with all the usual windows functions (file, edition,..). Resulting in a powerful but friendly soft. It can handle several tests simultaneously with a practical show / no show command and different curves colors & traces making results comparisons a really easy job. 18 different types of graphics and charts type information is available. A pass / no pass curve analyzer and a production module are other available functions.
