- FRF Analysis: response of the structure for different frequency ranges such as low medium and high frequency excitation.
Trailer Hitch Design and Analysis
Designing a trailer hitch involves several key considerations to ensure it’s safe, durable, and compatible with various towing applications.
At Caliber Technologies we have developed structural load cases based on intended use of the trailer hitch, including the types of trailers it will tow, maximum weight capacity, vehicle compatibility, and any relevant regulations or standards.
Conduct finite element analysis (FEA) or other structural simulations to evaluate the strength, stiffness, and durability of the design under various loading conditions.
Engineering simulation allows to generate multiple design concepts based on the requirements and analysis. Consider factors like hitch type (receiver, pintle hook, gooseneck, etc.), mounting location on the vehicle, and ease of use.



Truck Frame Design and Analysis
Designing a truck frame involves several key considerations to ensure it’s safe, durable, and compatible with various loading and operating conditions. At Caliber Tech, we have a detailed understanding of setting up frame architecture to reduce the weight as well as maximize structural rigidity in torsional, bending, and wrap. We apply a detailed finite element-based approach to optimize the design for strength, durability, and fatigue.
Trailer Suspension Design
A generic set of load cases was developed to analyze the Leaf Spring design for static strength, durability, and fatigue.
Redesign leaf springs, bracket attachment to frame, U-bolt preload determination, spring rate prediction, generation of load vs deflection curve.
Single bump event, roll event, longitudinal loading, lateral loading, vertical loading.


Chassis Components Design Process
In summary, designing chassis components involves several key steps and considerations to ensure the structural integrity, performance, and safety of the vehicle. Here’s an overview of the process:
- Define Requirements: Understand the requirements of the chassis, including vehicle type, intended use, weight distribution, and regulatory standards.
- Conceptual Design: Generate conceptual designs that meet the requirements. This involves selecting materials, determining the overall layout, and considering factors such as stiffness, weight, and manufacturability.
- CAD Modeling: Create detailed computer-aided design (CAD) models of the chassis components using specialized software. CAD models allow for visualization, simulation, and analysis of the design before physical prototypes are built.
- Structural Analysis: Perform structural analysis using finite element analysis (FEA) or similar techniques to evaluate the strength, stiffness, and durability of the chassis components under various loading conditions.
- Optimization: Refine the design iteratively based on the results of structural analysis and other simulations to optimize performance, weight, and cost.
- Manufacturing Considerations: Consider manufacturing constraints and processes during the design phase to ensure that the components can be produced efficiently and cost-effectively.
- Prototyping: Build physical prototypes of the chassis components to validate the design and verify its performance through testing and evaluation.
- Testing and Validation: Conduct comprehensive testing, including static and dynamic load testing, fatigue testing, and durability testing, to ensure that the chassis components meet design requirements and regulatory standards.
- Iterative Refinement: Based on the results of testing and validation, make any necessary refinements to the design to address any issues or deficiencies identified during testing.
- Documentation and Release: Document the final design specifications, including drawings, materials specifications, and manufacturing instructions, and release the design for production.
Throughout the design process, collaboration between designers, engineers, and other stakeholders is essential to ensure that the final chassis components meet all requirements and specifications. Additionally, incorporating feedback from testing and real-world use can help to further refine and improve the design.
