REBvibe vs MechSpace

REBvibe calculates fundamental vibration frequencies of rolling element bearings. The user can specify the bearing by either bearing geometry or the bearing model number. Features: - Inner Race Ball Pass Frequency and its harmonics (BPFI) - Outer Race Ball Pass Frequency (BPFO) - Ball Spin Frequency (BSF) calculation - Fundamental Train Frequency (FTF) - Results in CPM and Hz - Bearing selection using the bearing manufacturing database - Bearing selection based on the bearing geometry Disclaimer: This App is intended for educational purposes. Although the calculations were made with great care, it may contain errors or inaccuracies. Using the results of the calculations is the sole responsibility of the user.

MechSpace is the AR-powered mechanism design platform for students, robotics teams, and STEM educators. Build real mechanical systems in augmented reality, simulate them with real physics, and export competition-ready code — all from your iPhone or iPad. DESIGN MECHANISMS IN AR Place gears, motors, beams, and connectors on any flat surface. Parts snap together automatically with real connection physics. Build drivetrains, lift arms, intakes, and more with parts from your favorite robotics ecosystem. REAL PHYSICS SIMULATION Run your mechanism and watch it come to life. Simple mode helps you learn the basics. Advanced mode delivers engineering-grade analysis including torque calculations, gear ratio breakdowns, friction modeling, stall diagnostics, and power consumption tracking. SCAN YOUR REAL PARTS Point your camera at VEX parts and MechSpace automatically recognizes them using on-device machine learning. Detected parts are added to your digital inventory so you always know what you have available to build with. EXPORT ROBOT CODE Turn your AR builds into real robot programs. Export C++ or Python code for VEX V5 and VEX IQ. Generated code includes motor configurations, autonomous routines, and gear ratio calculations — ready to run in VEXcode. BUILT FOR LEARNING Track your progress with build streaks, unlock achievements like Gear Master and Code Wizard, and take on timed design challenges. MechSpace makes learning mechanical engineering fun and rewarding. SUPPORTED ECOSYSTEMS - VEX V5 - VEX IQ MechSpace is completely free — all features included, no subscriptions or in-app purchases.
