Automotive door panel fatigue testing machine

1、 Main purpose:
This product is suitable for interior parts of car doors. The various mechanical performance tests and analyses of car door handles are widely used in the automotive interior industry, quality inspection units, research institutions, and schools for professional customization. This product complies with relevant standards such as DEP_84610D.
2、 Equipment composition
The microcomputer controlled door panel deformation strength testing machine is mainly composed of a host, a control system, and a force acquisition system
The system consists of a displacement acquisition system, a computer control system, and specialized testing software.
Due to the need to test X. In both directions, dual electric servo cylinders are specially used.
In addition, the use of electric servo cylinders can achieve synchronous display of the deformation of the measuring point (pressure head) and the loading force.
1. HostAutomotive door panel fatigue testing machine
The host structure is a frame structure, consisting of a frame, base, test bench, electric servo cylinder, force sensor, connecting rod, fixture, etc. After adjusting the position of each bracket, it is connected to the base through bolts to form a rigid frame. Adjust the servo cylinder to align with the test position and lock it. Set the conditions on the test interface according to the test requirements, and then the test can be carried out. The position of the servo cylinder on the bracket can be moved, and the angle between it and the sample can be adjusted
2. Control system
The control system consists of speed control, displacement control, deformation and load control, etc. Adopting a fully digital closed-loop control system, it has three closed-loop control modes: stress, strain, and displacement. And assist the computer software control system in completing various experimental processes by communicating with the computer.
3. Collection system
The collection system consists of load measurement, displacement measurement, deformation measurement, etc. It completes the collection, processing, analysis, and curve drawing of various data during the experimental process.
4. Computer control and application testing software
The computer control system consists of a computer and its communication control system, acquisition system, and application testing software. The experimental process can be achieved through the experimental methods set by the experimental software, without the need for human judgment. In addition, a printer is equipped to print test reports as needed.
3、 Functional features:
Software platform: VC++programming is an independent installation dedicated software that can run on WINDOWS 98/2000/XP systems.
