KISSsoft supports the user with numerous calculations for different machine elements. The new KISSdesign^® module in KISSsoft^® supports the combination of these machine elements in building complex system transmissions containing any number of shafts, gears, and bearings.  

All rotating machine elements contain several characteristic frequencies, which can be one of the potential sources of noise in the transmissions. For example, gear meshing creates vibrations in its meshing frequency due to transmission error, manufacturing deviations, stiffness variation, torque fluctuations, as well as other sources. Therefore, knowledge of the characteristics and frequencies of the transmission can lead to an improved design and contribute to improved diagnostics of an existing transmissions.

During our webinar on November 15, 2023, various possibilities for the calculation of system characteristic frequencies, including gear and bearing frequencies, are presented. Furthermore, an overview of the new functionalities on the new system level in KISSsoft is provided, including:

    1.Basic theoretical background on:

• characteristic gear mesh frequencies
• characteristic bearing frequencies

2. Usage of characteristic frequencies in:

• the design phase of a system gearbox
• condition monitoring of gearbox

The loaded tooth contact analysis (LTCA) is crucial in understanding the deformation of gears and its impact on various factors such as noise generation, contact patterns, contact shocks, and torque variations. With the contact analysis feature in KISSsoft®, users can calculate tooth contact under specific torque and speed levels, thereby assessing the performance of gears and gearboxes. LTCA forms the foundation for a robust micro-geometric gear design, including lead and profile modifications. In this web-demo, you will gain insights into parallel axis and coaxial gearboxes, focusing on the following aspects:

• Loaded tooth contact analysis
• Stiffness calculation for teeth, shafts, bearings, housing, planet carrier, and gear body
• Analysis of system deformation and its impact on gear contact patterns
• Designing lead modifications for optimal strength and contact patterns
• Designing profile modifications for optimal behaviour in terms of power, NVH (noise, vibration, and harshness), efficiency, and contact temperature
• Optimization of modifications for duty cycles

The gear body of a gear is the main determinant of its stiffness. It is thus becoming clear in industry that designing a high-performance gear or drivetrain is barely possible without an accurate consideration of the gear body stiffness. KISSsoft® addresses this challenge by combining the FE method with analytical models. Our Software Developer, Dipl. Eng., MSc Theofanis Tsiantas, will show you:

• How to accurately calculate the stiffness matrix of a gear body with KISSsoft®
• Advanced modeling possibilities for gear bodies
• What is the effect of the gear body stiffness on different KISSsoft® calculations
• Future directions on extending the current modeling capabilities of gear bodies in KISSsoft®

Low noise and minimum vibrations are key to quiet and efficient operation. Profound NVH analysis is the answer to optimize noise and acoustics in conjunction with reduced vibration behavior of vehicles and vehicle components such as electric drive train systems.

KISSsoft® offers the user the possibility to perform an NVH assessment of gearboxes. The calculation of the noise excitation within the drive train is based on the forced vibration, which leads to the determination of the transient bearing loads.

These results are then transferred to the multi-body simulation program RecurDyn and applied to the flexible housing structure. This allows the system response of the housing as airborne sound to be viewed in steady state. In addition to the usual outputs, the engineer also has the radiated power ERP (Equivalent Radiation Power) at all points of the enclosure at his disposal.

Noise emissions from gear units in electric vehicles are a major problem. In practice, the profile form deviation is controlled strictly. For this reason, it is important to find a method that can be used to estimate the influence of the manufacturing accuracy. The application of this method to some modern gear units will be presented in our web demo:

• Application in the calculation
• Variation of the waviness
• Application to an industrial gearbox
• Application to an EV gearbox

Learn more about how the enhancements in KISSsoft® Release 2022 will make your gear design more efficient and refined. We are also excited to show KISSsoft® in a modernized look. Further topics:

• Influence of flank waviness on transmission error
• Tooth root fatigue strength from time series

The three-day event featured one topic per day addressing the specific requirements and challenges of e-drive transmissions, with particular attention to minimizing gear noise.

The first day was dedicated to the design of e-drive transmissions and looked at several aspects of gear design in an EV system environment. High rpm’s, reversal of load direction, low vibration excitation, high contact ratios, increased risk of scuffing, deformed housings - the design, optimization and service life calculation of gears for e-drives is a world of its own.

We will present various applications and provide an overview of the functionalities for manufacturing in KISSsoft®:

• Design tools with protuberance, semi-toppings and modified pressure angle
• Calculate tooth thickness dimensions for span widths, measurement over balls and graphical evaluation
• Collision check for power skiving and honing
• Evaluate grinding notches and tooth root stresses
• Calculate noise excitation from manufacturing simulation or measured gears
• Manufacture non-evolute gears such as park lock gears or sprocket gears

One of the key aspects in modern software development is to give end users sufficient freedom to adapt their working environment to current market requirements. In KISSsoft, various options are available for personalizing the software handling and tailoring it to your own needs.

Plastic gears offer the engineer more freedom to influence the tooth form, since they are usually manufactured using injection molding instead of hobbing processes. In this web demo, we will show you the options in KISSsoft for designing plastic gears.

The simulation of the NVH behavior is essential for certain types of gears and contributes significantly to the evaluation of gear optimization. The forced vibrations arise from the excitation in the gear mesh and are transmitted to the housing as variable forces and moments at the bearings. The radiated power is determined enabling an assessment of the noise behavior of the transmission. 

Language: English

The gear design process in KISSsoft is linked to manufacturing and measuring. For gears measured on Gleason Metrology Systems, the measurement data is looped back to KISSsoft.

Language: English

Process-dependent load spectra are often used for strength assessment of gears. Measured data as time series are then to be converted into a load spectrum. If the time series do not contain load reversal, the "Simple Count" method can be used.
