Torque Durability Test on Drive Shaft Components

Driveshaft components including axles and CV joints are subject to rigorous loading conditions in passenger cars and trucks. These components consist often of metallic and elastomeric components. It is important to test these components in fatigue and durability. Zwick offers a complete line of torsion and rotary test machines called Torsionline designed for these applications with a torque range of 200 to 6000 Nm. testControl and testXpert® software are used to control and to obtain and analyze test results from these systems.

Multi-axial Deformation Test on Tires

We have developed an advanced test system used to measure side stability of vehicle tires with different wheel and tire pressure combinations. This system allows OEM manufacturers to properly select supplier’s tires-wheel combinations, and tire suppliers to evaluate tire side stability under static-loading conditions. The unique Zwick load measurement platform allows axial and side loads to be accurately measured while the testControl controls the vertical, horizontal axes and tire air pressure.

Static Testing of Passenger Seat

Zwick has developed testing solutions for testing the seats of passenger cars. The systems are designed to determine the quality and durability of the fabricated seat. The system shown is used to test the sensor mat in the seat for proper airbag settings. It has a specimen loading carriage and a position-adjustable load cell to determine the required load to active the embedded sensor.

Durability Test on Foam for Seats

A universal electromechanical actuator integrated into a wide load frame is used to determine the compressibility properties of foam used in cars seats and interiors. testXpert® is used to quickly configure the cyclical test and monitor its progression with “at a glance“ test results. There are many other possible applications for this actuator.

Fatigue Testing of Bolted Joints

Ensuring a Good Connection

Dynamically loaded bolts and fasteners play
a vital role in the aerospace and automobile
industries, and even in automotive racing
applications. Fasteners subjected to alternating
loads are commonly found in combustion
engines, aircraft turbines, landing gears
and in the structural airframe components.

Testing of Disc Springs

Disc springs (sometimes known as plate springs) and disc spring sets have numerous applications in machine construction and the automotive sector, for example in clutch and brake systems. Customers need to determine the fatigue life and durability of such springs and understand how the spring properties change over time. It is also important that the quality of such springs meets a customer's specification requirements and this can only be verified with a sophisticated materials testing system.
