Self-developed Core Strength | 100kN Electro-hydraulic Servo Fatigue Testing Machine, Dynamic & Static Integrated Material Testing Platform

Material failure is rarely caused by one-time fracture, but by fatigue accumulation under millions of cyclic loads.

Jinan Nake's newly developed 100kN electro-hydraulic servo fatigue testing machine adopts our self-developed hydraulic power unit and 4-column floor-mounted high-rigidity mainframe. Equipped with imported American Celtron load cell and German DOLI fully digital controller, this single machine integrates static mechanical testing and dynamic fatigue tests. It delivers high-precision mechanical property testing solutions for metals, composite materials, polymers and other diverse materials.

Self-developed Hydraulic Power Unit - Stable Hydraulic Power Core

The hydraulic power unit is independently designed and manufactured by our company. With optimized servo hydraulic circuit, it features stable pressure output, controllable oil temperature, low noise and excellent heat dissipation. During long-duration continuous fatigue cyclic tests, minimal hydraulic fluctuation ensures sustained and stable high-frequency dynamic loading. It is easy for later maintenance, and oil supply parameters can be adjusted according to working conditions, suitable for long-term high-cycle and low-cycle fatigue durability tests.

4-column Floor-mounted High-rigidity Mainframe Frame

The floor-standing four-column integrated structure boasts sufficient frame rigidity, small deformation, no backlash and strong resistance to lateral force. The crossbeam can be lifted, lowered and locked conveniently with adjustable test space and easy specimen clamping. Thanks to outstanding vibration resistance of the floor-mounted structure, it effectively reduces interference of frame deformation on test data and guarantees coaxiality under high-frequency dynamic cyclic loading, ideal for long-term fatigue tests.

American Celtron Load Cell

Fitted with high-precision Celtron load cell, it offers fast force measurement response, good linearity and anti-drift performance. It accurately captures both static and dynamic loads and stably collects tiny load variations to ensure authentic and reliable force data.

German DOLI Fully Digital Controller

Equipped with original German DOLI controller with decades of technological accumulation in material test measurement and control. It supports multi-channel closed-loop control of force, displacement and strain, and enables shock-free switching of control modes during tests. It supports various loading waveforms including sine wave, triangular wave, square wave and random wave, featuring high sampling rate, rapid control response and strong software compatibility, complying with requirements of various Chinese and American standards for material mechanical tests.

Static Test Capabilities

Capable of conventional static mechanical tests such as tension, compression, bending and shear of materials to obtain basic mechanical indicators including yield strength, tensile strength, elastic modulus and elongation at break. Multiple control modes including constant stress, constant strain and constant displacement are available.

Dynamic Fatigue Test Capabilities

High-cycle fatigue, low-cycle fatigue and component durability cyclic tests. It simulates working conditions of materials under repeated alternating loads to determine fatigue limit, generate indicator curves and predict service life of materials and components.
