With broad expertise in a wide range of applications within the commercial vehicle market, TRIZ® designs and develops advanced applications and solves complex engineering challenges while taking concepts to a fully integrated solution. Highlighted below are many of our core capabilities.

Medium and heavy duty vehicle integration

CHASSIS DESIGN – The sub-structure of the vehicle chassis design begins with a high-level conceptual layout consisting of all the interfaces between systems, including body interfaces, frame and other subsystems such as suspensions, engines, transmissions and brakes.

COOLING PACK INTEGRATION – The development of a “to-specification” cooling system is critical to vehicle integration. Well-defined, efficient cooling is paramount for both present and future engine emissions requirements.

CAB DESIGN INTEGRATION – Integration of a cab onto the chassis, consisting of all interfaces between systems, including electrical systems and ergonomics.

BODY INTEGRATION – Various vehicle body integrations onto applicable chassis, with development of full interfaces between systems.

Emissions design for vehicle level application to Euro and US Standards

TRIZ®‘s track record reflects successful integration of a variety of engines from various manufacturers that comply with stringent USA and European exhaust emission regulations for the following “emission change-overs:”

  • 2002, 2007, 2010, 2013
  • Tier 3 and Tier 4 Diesel
  • Natural Gas (CNG and LNG)

Engineering for powertrain, hybrid applications, weight reduction, system optimization

POWER-TRAIN INTEGRATION – We’ve participated in numerous engine-transmission integrations for medium and heavy-duty vehicles involving:

  1. Matching the engine and transmission to ensure acceptable performance, while keeping fuel economy in check
  2. Fitting the power train into the vehicle within the specified body and vehicle constraints
  3. Designing engine and transmission mountings
  4. Ensuring that drive shaft accelerations and vibrations are within acceptable levels
  5. Developing cooling systems, piping and other interfaces, and electrical harnesses

Vehicle performance improvement for noise, vibration, safety and efficiency

DRIVE-TRAIN INTEGRATION – TRIZ® provides drive-train integration services that include specifying the final drive axles, drive shafts, wheel rims and tires to ensure that the power-train and drive-train are optimally integrated.

ERGONOMIC LAYOUT – Ergonomic layout is very important for driver comfort and vehicle operation. Using 3D models which have human movement data built into them, we can position vehicle controls in virtual space to optimize driver comfort.

BRAKE SYSTEM INTEGRATION – Our integrated solutions use standard components including tubing, ABS systems, flexible piping and any additional engineering requirements to create brake system configurations from brake pedal to wheel ends.

STEERING AND SUSPENSION INTEGRATION – We offer vehicle suspension integration using standard components. We use 3D simulation software to test suspension and steering systems for optimum geometries and component configurations.

PIPE ROUTING – We ensure that piping systems such as brake tubing, steering tubing, fuel lines and others are carefully routed along the chassis so that they can be assembled easily during production and that they have full drawings for full repeatable production.

Vehicle failure investigation for structural integrity

FINITE ELEMENT ANALYSIS – TRIZ® uses Finite Element Analysis (FEA) to model and fatigue test components during the concept and development phase of the designs. Both linear and nonlinear codes are used, as required.

Manage compliance and testing capabilities

ADAMS DYNAMIC SIMULATION – TRIZ® uses MSC Adams to simulate vehicle dynamics and kinematics. This can be used to calculate input loads by passing the vehicle over pre-determined obstacles to simulate test track conditions. By combining multiple events, a duty cycle can be formulated which can be applied via FEA during early stages of vehicle development. It can reduce the number of prototypes required for data collection and durability testing.

Adams is also used to calculate loads of mechanisms such as brake pedals and park brake systems. In this case, flexible models from FEA simulations can be used to capture the modal and stiffness behavior of moving components under load.
