XWP-X3000

Cantilever beam high-temperature rotating bending fatigue testing machine

1、 Purpose and structural characteristics

1. This machine is used forTesting the durability performance of metal materials under high-speed rotationThis machine adopts a small inertia servo motor as the driving unit, and an external high-precision rotary encoder is connected to the spindle as the speed sensor, with high speedDSP+ARM,As the core control unit for motor drive and encoder acquisition, it ensures the accuracy and stability of speed control at high and low speeds.

The color touch screen displays the frequency of emission, theoretical speed, real-time motor speed, and spindle speed, and can be set as needed. It has multiple levels of speed, which can be executed independently from low to high, and the rotation holding time can be set after the speed is reached. Automatic data recording.

2. According to the characteristics of the tested sensor, a specialized magnetic mounting bracket is configured. The sensor spindle adopts a top structure, and the rear tailstock can move forward and backward (reliably ensuring coaxiality). The rotation of the sensor spindle is loaded by a grinder

3. The fixture uses elastic front and rear clamps to hold the sample, and the clamp is connected to the spindle elastic cylinder clamp to achieve precise fit, ensuring that the radial runout of the clamped sample meets the requirements of navigation marks and national standards.

two The loading form is divided into: as shown in the following figure

Single point loading（cantilever beam）

Two-point loading Four point loading（simply supported beam）
