Our client is a leading manufacturer of joinery in France.
Tested product
Openings and joinery
Openings are French windows, doors, windows and bay windows of all types. Joinery is the assembly (design, construction, assembly) of all openings, which can be made of wood, PVC or aluminium.
Objective
Carry out endurance tests on all types of joinery and openings in accordance with standard NF EN 1191 (Windows and doors - Resistance to repeated opening and closing).
Problematic issues
The test rig must be mobile (easily transportable) and allow tests to be carried out on existing steel gantries.
Solution and result
The test bench is composed of :
- 1 base mounted on legs, themselves fitted with retractable wheels allowing the bench to be transported
- 1 rotary axis for the actuation of the opening part (in cycling mode)
- 1 linear axis for operating the opening (in cycling mode)
- 1 rotary axis and 1 linear axis for operating the hardware (cycling)
- 1 motorised vertical adjustment axis
- 1 manual adjustment of the axis in orientation and position
- 1 control software
Actuators for operating the locking device
The rotary actuator is used to operate the handles. It is equipped with torque and displacement measurement and can be controlled in position, speed and torque. The linear actuator is used to operate the bay locks. It is equipped with a force and displacement measurement and can be controlled in position, speed and force.
Control
The software that controls the endurance bench is simple to use and intuitive. The automatic test scenarios are programmable. The characteristic values of each cycle (cycle number, maximum force, minimum force, average force, position, etc.) and all force/displacement curves are saved in a specific file.
This mechanical endurance test bench performs "type" tests, in order to verify that the tested products have all the assigned characteristics specified for them. This bench is used in several test laboratories to test the fatigue life of products before they are marketed.
