Embodiment

[0050] Apply the general fatigue test control system provided by the present invention to implement the fatigue test of a certain type of automobile with four doors and two covers, as follows:

[0051] Step 1: Analyze the specific actions included in the fatigue test: there are three types of actions, including opening and closing the front cover, opening and closing the rear cover, and opening and closing the doors on both sides. Among them, the action combination of opening and closing the front cover is to open the front cover lock → open → close the front cover lock → close; the combination of opening and closing actions of the rear cover is to open the rear cover lock → open → close the rear cover lock → close; The combination is to open the inner lock→pull the door→close the inner lock→close the door→open the outer lock→pull the door→close the outer lock→close the door.

[0052] Second step: through the general fatigue test control system provided by the present inventio...

Abstract

The present invention discloses a general fatigue test control system. The system comprises: a control instruction information storage unit (100) configured to generate a preset test control input information table in advance; a test control unit (200) configured to connect with the control instruction information storage unit (100) and a plurality of electromagnetic relays (300); a plurality of actuator switch controllers (300) configured to correspondingly control on-off of actuators (400) according to an actuator switching control instruction sent by the test control unit (200); and a plurality of the actuators (400) configured to perform one-to-one correspondence connection with a plurality of actuator switch controllers (300). The general fatigue test control system satisfies fatigue test control demands of different products performing complex motions, reduces the hardware economic input for the fatigue test, reduces the test user economical burden, reduces the whole time required for product fatigue test and facilitates wide production application.

Description

technical field [0001] The invention relates to the field of fatigue test technology, in particular to a general fatigue test control system. Background technique [0002] At present, the fatigue test is a necessary means to identify whether the product structure or equipment can meet the expected service life and ensure the integrity of the product structure or equipment in the actual use environment. System security and other aspects are extremely important. [0003] For conventional fatigue tests, it is mainly to simulate the real working state and working life by periodically loading the product structure, such as repeatedly pressing the keys of the computer keyboard to verify whether the service life of the power keyboard meets expectations Design requirements. [0004] For tests with a single reciprocating action mode and no need for precise control, an open-loop control method is usually adopted, usually controlled by a programmable logic controller PLC or a digital...
