Testing of suspension systems, chassis and body components

BOSMAL specialises in a comprehensive examinations of the chassis, parts and components of the chassis, body and body equipment. In the field of body and body component research, BOSMAL has the ability to configure test systems for multi-axis loading (forces, torques) of various parts and assemblies. We perform functional, endurance and fatigue tests (including also for the industry sectors other than automotive).

Comprehensive Suspension System Testing

We specialize in precise strength and fatigue testing of key suspension system components. Our laboratory is equipped with advanced apparatus that allows us to conduct tests on components such as control arms, providing reliable data on their deformation, stress, and service life.

Swingarm deformation and fatigue test measurements

Scope of Testing Services

• Fatigue and Strength Testing of Control Arms We conduct single- and multi-axis fatigue tests that simulate loads occurring in real-world operating conditions, allowing for a precise assessment of component durability.
• Deformation Measurement and Stress Analysis (Strain Gauge Testing) We perform detailed stress measurements using strain gauges, which enables the identification of critical areas in the tested part and the verification of design assumptions.
• Optical 3D Deformation Measurements (TRITOP System) We offer advanced, non-contact deformation measurements of the entire object’s geometry using the optical TRITOP system (a service provided in cooperation with BOSMAL’s partners).

Technical Specifications and Test Equipment

Our technical capabilities are based on modern equipment and specialized software:

• Test Rig
  • Linear actuator with a force of up to 50 kN, controlled by a high-precision MTS FlexTest 60 controller.
  • Capability of simultaneously loading the test object with more than one actuator.
• Test Conditions and Data Acquisition
  • Tests are conducted at ambient temperature.
  • Continuous load signal recording throughout the entire test.
• Specialized Software
  • MTS MultiPurpose TestWare (MPT): Advanced software for test control and data acquisition.
  • ReliaSoft Weibull++7: Software for advanced statistical data analysis, reliability assessment, and lifetime prediction.

Automotive Axle Durability and Fatigue Testing

We specialize in advanced durability and fatigue testing of complete automotive axles. Our test rigs allow for the simulation of complex loads, reflecting real-world operating conditions and verifying the strength, reliability, and safety of key suspension components.

Sample Axle Test Procedures

We conduct a wide range of standard and non-standard tests, customized to client specifications. Our testing capabilities include, but are not limited to:

• Lateral force test
• Longitudinal force test
• Vertical force test
• Bending force test
• Brake reaction test
• Axle rolling test
• Contribution of roll rate test
• Spring force test
• Shock absorber force test
• Watt linkage test

Custom Test Programs

We are capable of developing and conducting a dedicated test program that precisely replicates the specific loads and working conditions for your product. Contact us to discuss your project details.

Subframe Durability and Fatigue Testing

We specialize in durability and fatigue testing of front suspension subframes. Our tests provide a comprehensive verification of the structure’s strength, simulating loads from the running gear, steering system, and powertrain in a controlled laboratory environment.

Scope of Tests for Front Subframes

We conduct a series of tests to evaluate the subframe’s behavior under key operational loads. Our standard procedures include:

• Lateral force test
• Longitudinal force test
• Steering gear force test
• Stabilizer force test
• Engine force test

Validating Design and Ensuring Durability

Fatigue testing of subframes is a key element of product validation. It allows for the early detection of potential structural weaknesses and confirms that the component meets all requirements for durability and safety.
