Strong CAE software for oil pumps 'SimericsMP+'

Simulate the flow characteristics of volumetric pumps such as gear pumps and vane pumps! A CAE software specialized for pumps that other CAE software struggles with!

SimericsMP+ is a fluid simulation tool designed to calculate the transient characteristics of various volumetric pumps, compressors, and valves. It is developed based on the thermal fluid simulation tool Simerics MP and utilizes all the features of Simerics MP. 【The following fluid analyses are possible】 ■ Free surface flow ■ Flow considering the compressibility of air contained in liquids ■ Pressure pulsation and water hammer effects ■ Coupling of pump flow with the rigid body motion of valves and cam rings ■ Flow in low to medium vacuum conditions ■ Compressible flow (subsonic) ■ Cavitation ■ Time variation of flow field (velocity vectors, pressure), flow rate, fluid forces, and torque The greatest strength is the ability to automatically create meshes even for clearances in the µm range, which is difficult with other general-purpose fluid analysis software!! Recently, there has been an increase in achievements with oil pumps for automobiles and construction machinery, with examples such as vane pumps for power steering and CVTs, and trochoidal pumps for engine lubrication. *There is a lot of information that cannot be posted online. Especially, the actual mesh creation and movement should definitely be demonstrated in a demo!

basic information

(1) Automatic generation of calculation meshes! Even for complex flow paths, automatic generation of calculation meshes is possible with simple button operations. Additionally, for pump chambers involving rotation/volume changes, high-precision calculation meshes can be automatically generated using a dedicated mesh creation module. It is possible to automatically execute the movement/rotation/deformation of high-precision meshes without the need for tedious tasks. (2) Fluid analysis of various gear pumps is possible! SimericsMP+ has mesh creation capabilities for various pumps, including different types of gear pumps, making it easy to perform calculations for a wide range of pumps. It also includes mesh creation functionality for valves, allowing for calculations of flow paths that include valves, and coupled analysis is also possible. (3) More accurate modeling of aeration/cavitation! It includes a highly accurate cavitation model, allowing for the prediction of non-condensable gas expansion and steam generation due to cavitation. (4) Calculation of free surface flow As a new feature, the calculation of free surface flow has become possible. It is now possible to analyze oil splashing inside the gearbox and oil suction from the oil pan during pump startup.

Applications/Examples of results

SimericsMP+ (Simerics MP Plus) is primarily used by automobile manufacturers and automotive-related parts manufacturers in Japan, with numerous achievements in oil pumps used in automotive AT and CVT, as well as engine oil pumps. Additionally, it has a wide range of implementation achievements not only in the automotive industry but also globally. Examples of achievements worldwide by the developer can be found at: http://www.simerics.com/testimonials/ There are many cases where companies that have already purchased multiple fluid analysis software domestically, as well as those overseas, have purchased it for the ease of use, improved accuracy, and reduced calculation time in analyzing volumetric pumps such as gear pumps and vane pumps. A case study on fluid analysis of a vane pump using 'SimericsMP+' was published in KYB Corporation's KYB Technical Report No. 53 OCT. 2016.
