In-Situ Tension-Compression Stage for Nanoindenter | Reverse Engineered Kammrath & Weiss | TI-950 Compatible · 模型 97457
Reverse-engineered 3D model of a micro tension/compression testing stage, originally manufactured by Kammrath & Weiss (~2002), redesigned as an economically competitive alternative for research institutions. Designed to mount directly on the Hysitron TI-950 Nanoindentation Triboindenter (300×300×50 mm working envelope). Enables in-situ mechanical testing — tension and compression — of small specimens (demonstrated for 3×3×2 mm Yttria-Stabilised Zirconia) while simultaneously performing nanoindentation. ── MECHANICAL SYSTEM ── - Drive: NEMA 23 stepper motor (425 in·ozf / ~3 N·m) - Reduction train: Belt/pulley (1:1) → Worm-helical stage (20:1) → Twin worm-helical stages (20:1 each) | Total ratio: 400:1 - Actuation: Counter-wound lead screws (M10×1 mm pitch, RH + LH) for symmetric specimen centring - Bridge speed: 6 mm/min | Max thrust: ~483 kN - Load sensing: Transducer Techniques SSM-10K-C (10,000 lbf / 44.5 kN) ── COMPONENTS ── - Commercial parts: Misumi pillow-block bearings, GT2 timing pulleys & belt - Custom-machined: Lead screws (AISI 1045), bronze nuts & spacers (932 Bearing Bronze), helical gears, worm gears, fixture plate, bridges, compression clamps - Structural plates machined by PCB Way ── FILES INCLUDED ── - SolidWorks 2024 full assembly (.SLDASM) + all part files (.SLDPRT) - Kinematic chain calculator + YSZ fracture force workbook (.xlsx) - Reference images from original Kammrath & Weiss device (TUHH, 2002) Developed at CINVESTAV Campus Querétaro, Mexico.
