Customer Oriented R&D

3D CAD model parts & 2D drawing

Requirements and Features:
We define the vehicle’s intended use (e.g. passenger car, off-road vehicle, sports car) and specific performance requirements for the steering, suspension and brakes.
Conceptual design:
We can create a conceptual layout of the chassis, taking into account factors such as weight distribution, packaging constraints and intended vehicle dynamics.
We can choose the type of suspension system (eg independent, solid axle, multi-link) according to the vehicle’s requirements and intended use.
Suspension System Design:
We select the suspension geometry and components (shock absorbers, springs, control arms) that will best provide the desired ride comfort, handling and stability.
We use suspension simulation tools to analyze and optimize the performance of the system under various conditions.
Steering System Design:
We can select the appropriate steering mechanism (rack gear, rotating ball, etc.) according to the size, weight and intended handling characteristics of the vehicle.
We design the steering link, column and components to provide precise and responsive steering control.
Brake System Design:
We can determine the braking requirements according to the weight, speed and intended use of the vehicle.
We select the type of braking system (disc, drum, anti-lock brakes) and properly sized components (calipers, rotors, drums) to meet braking performance targets.
Integration and Packaging:
We ensure that steering, suspension and brake components are properly integrated into the chassis, taking into account packaging constraints and space limitations.
Manufacturing and Production:
We finalize the design for production, taking into account factors such as ease of assembly, cost-effectiveness and scalability.
Supplier selection:
We identify suppliers for various chassis components and collaborate with them so we can ensure quality and on-time delivery.
2D Drawings:
We can make technical drawings and assembly drawings of the chassis parts.

Chassis kinematic architecture

Kinematic Analysis: We can use kinematic analysis. This involves studying the motion and behavior of various components in response to different inputs, such as steering angles, suspension movements, and wheel rotations.
Simulation and Testing: We use the chassis kinematics models from CATIA to simulate and test different driving scenarios such as cornering, braking and rough road conditions.Simulations help us understand how chassis and suspension components interact and make the necessary adjustments to improve vehicle dynamics.
we can design kinematic models of the following suspension types:
– Double wishbone
– Mcpherson
– Multilink suspension
– Rigid axle
– Twist beam
– Active suspension systems

Chassis – PWT Kinematic & Envelopes

We can create a chassis kinematic envelope, commonly used to describe the range of motion and geometric constraints a vehicle’s chassis can accommodate without interference or collision. This envelope defines the maximum and minimum limits of movement of various components within the chassis such as wheels, suspension, steering mechanisms and other related parts.
Manufacturability: The manufacturing process of a vehicle is influenced by the kinematic envelope. Components need to be manufactured and assembled in a way that allows them to operate as intended without violating the envelope’s constraints.
Customization: Where vehicles may have adjustable characteristics (e.g. suspension height, steering characteristics), understanding the kinematic envelope helps us set appropriate limits to avoid excessive adjustments that could compromise safety or performance.
Overall, the chassis kinematic envelope is a critical concept in vehicle design and engineering, helping to ensure that the vehicle operates safely, efficiently, and effectively within the defined range of motion for its various components.

EDU motion & Envelope

While the vehicle is driving, we analyze the movements coming to the EDU (electronic drive unit) with IPS. We use these movements to control the parts around the EDU, at the same time, we observe the bushing movements of the engine.
We create the envelope file using motor movements, then we check the clearances with this envelope.

Sensor cable and brake hose under dynamic effects in the suspension

The dynamic behavior on cables and hoses can play a decisive role in the suspension (sensor cable or brake hose).
Rapid changes in motion or excitation during rebound and compression in the suspension can result in dynamic effects that can be simulated with the dynamic module after the quasi-static design in IPS.
As a result, we use it for virtual validation of dynamic effects on flexible components to examine layout, design space, and durability to reduce hardware prototypes.

Engine hoses – Mechanical behaviour

This design project is about the ideal hose length in the engine compartment, which is required to analyze the stress during engine movement.

For this purpose, we can automatically stretch the hoses from the specified connection points and map the kinematic movement by loading the CAD model of the vehicle into the Simulation program we use. Hose lengths can be changed and the corresponding stress displayed in real time by the software. So we can successfully determine the optimum length. In addition, in this simulation program, Cable Simulation can be used to determine optimum routing with fixing points for clips and hose guides, thus significantly reducing material tension and installation space requirements.
