Sheppard follows the Advanced Product Quality Planning (APQP) process during the research and development of new products in accordance with our ISO/TS 16949 certification. The purpose of this system is to guide the team in a direction to deliver a product that meets the customer’s need through project planning, design assessment, and product validation.
Product development engineers use the design failure mode and effects analysis (DFMEA) tool to make decisions that mitigate failure modes throughout the development phase and prior to production launch. The DFMEA is supported by engineering calculation and assessment which may include tolerance studies, CAD models, finite element analysis, mechanism simulations, and validations tests.
Our onsite engineering and technology center has the capability to perform both destructive and non-destructive testing for product development and validation. These tests can be conducted in accordance with: national and industry standards (e.g. ASTM and SAE); customer design requirements; or internal Sheppard procedures. Test programs are often used to evaluate product for the following characteristics:
- Hydraulic pressure and flow response
- Noise signature
- Cycle life durability
- Impact load resistance
- Ultimate strength performance
- Stress/ strain condition
- High and low temperature exposure
- Environmental susceptibility
- Ergonomic accessibility
In addition to lab testing, we have the ability to instrument vehicles with data acquisition equipment to evaluate “on road” vehicle performance and driver preferences.
